Policy templates Vulnerability and Patch Management Policy

Vulnerability and Patch Management Policy template and examples

A vulnerability and patch management policy sets how a company finds security weaknesses in its systems, software and devices, how it rates them, how quickly each severity must be fixed and what that time is counted from, how security updates are installed and who approves an exception. This generator writes one for your company, as a single document.

Who needs one

  • Companies preparing for a SOC 2 report. Criterion CC7.1 has the entity use detection and monitoring procedures to identify new vulnerabilities, and a point of focus under it speaks of vulnerability scans “on a periodic basis” with deficiencies remediated “on a timely basis”. The criteria give no number of days. A written policy is where you say what “timely” means for you, and its records are what show you kept to it.
  • Companies working towards ISO 27001. According to published summaries, Annex A control 8.8, “Management of technical vulnerabilities”, asks that information about technical vulnerabilities is obtained, that exposure to them is evaluated and that appropriate measures are taken. We have not read the standard itself.
  • Companies that answer security questionnaires. HECVAT 4 asks “Do you have a documented patch management process?” and whether a policy and procedure manages how critical patches are applied to all systems and applications. Version 4.0.2 of the CSA CAIQ asks whether policies and procedures to identify, report and prioritise the remediation of vulnerabilities are established, documented, approved and reviewed at least annually.
  • Companies that take payment cards. PCI DSS requirement 6.3.3 has patches or updates for critical vulnerabilities installed within one month of release, and requirements 11.3 and 11.4 ask for external scans by an approved vendor and for penetration tests, which the generated policy does not set. The framework table below says what to add.
  • UK companies working towards Cyber Essentials. Its requirements give 14 days from release for updates that fix critical or high-risk vulnerabilities. The scheme is not in the generator’s list of frameworks: type “Cyber Essentials” under “Other” and the generated policy gives a High vulnerability 14 days and adds a rule for installing those updates within 14 days of release.
  • Small teams, and companies with no servers. A policy that promises a fix within 48 hours is broken the first weekend nobody is free to make one. For a company of 50 or fewer people the generated policy gives a Critical vulnerability 14 days, not 7. Answer “We only use SaaS tools, no infrastructure of our own” and it has no monthly scan of your own systems, and covers devices and the services suppliers run. No example on this page shows that version.

What to include

A scope by kind of system
The devices staff use and the services suppliers run, for every company. The generator adds the infrastructure you run, the software you build with the components it uses, and the systems you manage for customers, each only where it applies. Define the terms once, above all “fix” and “temporary measure”, so that blocking access to a weakness is never recorded as fixing it.
Roles that exist
One role that keeps the policy, a more senior role or the board that approves it, the staff a vulnerability is assigned to, and all staff. The generator adds managers at 11 or more people and creates no vulnerability manager, system owner or security team.
How vulnerabilities are found
Suppliers’ security notices, read within a stated time. Where you run infrastructure, a scan of it at a stated interval, and a scan from outside your network of anything that can be reached from the internet. Where you manage systems for customers, a scan of those. Where you build software, a check of each change and alerts on the components it uses. Reports from staff and outsiders. And one sentence saying which day counts as the day a vulnerability was found.
A severity table with a time for each rating
The table a customer’s reviewer looks for first. The examples have four ratings, Critical, High, Medium and Low, each defined by a CVSS base score or the supplier’s own rating, and each with a number of days. Say which rating applies when the two disagree, who may change a rating, and what happens to a vulnerability known to be used in real attacks.
What each time is counted from
Most templates give a number of days and no starting point. The examples give one for each kind of vulnerability: for a supplier’s security update, the later of the day it is released and the day the company finds the vulnerability; for a setting, the day it is found. They also say what happens when no update exists yet, when a rating changes, and when a vulnerability counts as fixed.
Installing security updates
A time for updates on the devices staff use (14 days from release in the examples), automatic updates wherever they are offered, updates taken only from the supplier, and what is done when an update would break something. Say that a fix is a change and goes through your rules for change management.
Services that suppliers run
You cannot install an update on a service someone else runs. The examples say the supplier fixes the parts it runs and the company fixes the parts it controls, such as the settings, and set what the company does when it learns of a Critical or High vulnerability in such a service.
Unsupported software and devices
Software whose supplier no longer releases security updates cannot be fixed by an update. In the examples it is recorded as a High vulnerability from the day support ended, and an exception for it is approved only where a temporary measure cuts it off from the internet and from every system that does not need to reach it.
Exceptions to a time
What a request says, the reasons that count, who approves at each severity, how long an exception may last and what happens when it ends. In the examples an exception lasts no longer than 30 days for a Critical vulnerability, 3 months for a High one and 12 months for a Medium or Low one, and other work taking priority is not a reason.
What a vulnerability record holds
The examples list seven things: what and where, severity, dates, who it is assigned to, any temporary measure, the fix and any exception. The record may be kept in the tool that found the vulnerability. Say how long records and scan results are kept: at least 3 years in the examples, which is the company’s own figure.
Monitoring and reporting
A look at every open vulnerability at a set interval, what is done when one becomes overdue and who is told, and a report to the approving role with counts by severity. The examples set once a month for the look and every 3 months for the report.
Other exceptions, breaches and review
Who approves an exception to any other rule, what counts as a breach (hiding a vulnerability, turning off automatic updates or a scan without approval, or a record known to be untrue), that nobody is penalised for reporting a vulnerability or a missed time in good faith, and when the policy itself is reviewed.

What frameworks require

FrameworkReferenceRequirement
SOC 2 (Trust Services Criteria)CC7.1 and CC8.1“To meet its objectives, the entity uses detection and monitoring procedures to identify (1) changes to configurations that result in the introduction of new vulnerabilities, and (2) susceptibilities to newly discovered vulnerabilities” (CC7.1). A point of focus under it (the detail listed under each criterion) has the entity conduct vulnerability scans “on a periodic basis and after any significant change in the environment” and remediate identified deficiencies “on a timely basis”; the 2022 revision reworded it and added infrastructure and software scans. The 2022 revision also added a point of focus under CC8.1, “Manages Patch Changes”: a process to identify, evaluate, test, approve and implement patches “in a timely manner”. The criteria say that using them “does not require an assessment of whether each point of focus is addressed”. Two copies were read for this page: CC7.1 and CC8.1 give no number of days in either, and neither copy mentions CVSS.
ISO/IEC 27001:2022Annex A 8.8The control is titled “Management of technical vulnerabilities”. According to published summaries of it, information about technical vulnerabilities of information systems in use is obtained, the organisation’s exposure to such vulnerabilities is evaluated and appropriate measures are taken, and the summaries give no number of days and no interval for scans. We have not read the standard itself, so check the wording against your own copy. The generated policy does not name ISO 27001, even where you select it.
PCI DSS v4.0.1Requirements 6.3.1 and 6.3.3Vulnerabilities are identified from industry-recognised sources and given a risk ranking that identifies, at a minimum, those considered high-risk or critical to the environment (6.3.1). Patches or updates for critical vulnerabilities, as that ranking identifies them, are installed within one month of release, and all others “within an appropriate time frame as determined by the entity’s assessment of the criticality of the risk to the environment” (6.3.3). The guidance beside 6.3.3 gives 60 days for high-risk vulnerabilities and 90 days for others as an example, not as a requirement. The standard counts from release. The generated policy counts a supplier’s update from the later of its release and the day the company finds the vulnerability, so an update found late can fall due more than a month after release: a company in scope should check its Critical row against this requirement.
PCI DSS v4.0.1Requirements 11.3 and 11.4Internal vulnerability scans at least once every three months, with high-risk and critical vulnerabilities resolved and rescans to confirm it (11.3.1). External scans at least once every three months by a PCI SSC Approved Scanning Vendor, a scanning company on the PCI council’s approved list (11.3.2). Internal and external penetration testing at least once every 12 months and after any significant infrastructure or application upgrade or change (11.4.2 and 11.4.3). The guidance says “Scanning for vulnerabilities alone is not a penetration test”. The generated policy does not mention PCI DSS, even where you select it: it has a scan at least once a month where you run infrastructure, names no scanning vendor and sets no interval for a penetration test, so a company in scope adds those.
Cyber Essentials v3.3 (UK)Security update managementSoftware in scope must be licensed and supported, have automatic updates enabled where possible, and be updated within 14 days of release where the update fixes vulnerabilities the vendor describes as critical or high risk, where it addresses vulnerabilities with a CVSS v3 base score of 7 or above, or where the vendor gives no details of their level. A footnote calls 14 days “a reasonable period”. Unsupported software must be removed from devices, or removed from scope by a defined sub-set that prevents all traffic to or from the internet. The requirements give no period for doing so, and the word “exception” does not appear in the v3.3 document. Where you type Cyber Essentials among your frameworks, the generated policy gives a High vulnerability 14 days and installs those updates within 14 days of release; it still gives unsupported software the time of a High vulnerability before it is overdue, which the scheme does not.
CIS Controls v8.1Safeguards 7.1 to 7.7Control 7 is “Continuous Vulnerability Management”. It asks for a documented vulnerability management process, reviewed annually (7.1), and a risk-based remediation strategy reviewed monthly or more often (7.2); operating system and application updates through automated patch management on a monthly, or more frequent, basis (7.3 and 7.4); and, from implementation group 2, automated scans of internal assets quarterly or more often and of externally exposed assets monthly or more often (7.5 and 7.6), with detected vulnerabilities remediated on a monthly, or more frequent, basis (7.7). The monthly figures are how often the work is done; the safeguards give no number of days for a severity.
NIST SP 800-53 Rev. 5RA-5 and SI-2RA-5 has the organisation monitor and scan for vulnerabilities at a frequency it defines, and remediate legitimate vulnerabilities within response times it defines, “in accordance with an organizational assessment of risk”. SI-2 has it identify, report and correct system flaws, test updates before installation, and install security-relevant updates within a time period it defines “of the release of the updates”. Each figure is a parameter the organisation sets; the controls give none. Whether these controls apply to you depends on your contracts, and the generated policy names none of them.
NIST SP 800-171 Rev. 303.11.02 and 03.14.01Monitor and scan the system for vulnerabilities at an organisation-defined frequency and when new vulnerabilities affecting the system are identified, and remediate system vulnerabilities within organisation-defined response times (03.11.02). Identify, report and correct system flaws, and install security-relevant software and firmware updates within an organisation-defined time period of the release of the updates (03.14.01). Rev. 3 superseded Rev. 2 in May 2024. The Rev. 3 document does not contain the word “penetration”.
CMMC Level 2 (32 CFR 170.14)NIST SP 800-171 Rev. 2, 3.11.2, 3.11.3 and 3.14.1CMMC is the US Department of Defense’s certification for its contractors. The rule makes the Level 2 requirements identical to those of NIST SP 800-171 Rev. 2, which NIST withdrew in May 2024 when Rev. 3 replaced it: “Scan for vulnerabilities in organizational systems and applications periodically and when new vulnerabilities affecting those systems and applications are identified” (3.11.2), “Remediate vulnerabilities in accordance with risk assessments” (3.11.3) and “Identify, report, and correct system flaws in a timely manner” (3.14.1). The rule says “periodically” means at regular intervals, with an interval of no more than one year in many CMMC requirements. None of the three gives a number of days. The generated policy does not mention CMMC, even where you select it.
NIST Cybersecurity Framework 2.0ID.RA-01, ID.RA-07 and PR.PS-02“Vulnerabilities in assets are identified, validated, and recorded” (ID.RA-01). “Changes and exceptions are managed, assessed for risk impact, recorded, and tracked” (ID.RA-07). “Software is maintained, replaced, and removed commensurate with risk” (PR.PS-02). The framework gives no interval and no number of days, and the framework document itself (NIST CSWP 29) does not contain the word “patch”.
NIST SP 800-40 Rev. 4Sections 3.3 to 3.5NIST’s guide to planning enterprise patch management (April 2022; Rev. 3 is withdrawn). It is guidance and sets no deadline. It suggests planning for routine patching, emergency patching, emergency mitigation and unpatchable assets, says a maintenance plan includes “the timeframes for beginning and ending each action”, and says organisations “should closely track and monitor all exceptions to maintenance plans” and review them regularly.
HIPAA Security Rule45 CFR 164.308(a)(1) and (a)(8)The rule in force asks for an accurate and thorough assessment of the potential risks and vulnerabilities to electronic protected health information (risk analysis), security measures sufficient to reduce risks and vulnerabilities to a reasonable and appropriate level (risk management), and a periodic technical and non-technical evaluation. Sections 164.306, 164.308 and 164.312 do not contain the words “patch”, “scan” or “penetration”. A rule proposed in January 2025 would add vulnerability management, with 15 calendar days for a critical risk and 30 for a high one in its preamble, and a penetration test at least once every 12 months. A search of the Federal Register on 8 October 2026 found the proposal and no final rule, so those figures are not law. The generated policy does not mention HIPAA, even where you select it.
DORA: Delegated Regulation (EU) 2024/1774Article 10Financial entities develop, document and implement vulnerability management procedures and patch management procedures. Automated vulnerability scanning of ICT assets supporting critical or important functions is performed “on at least a weekly basis”. The entity verifies whether its ICT third-party service providers handle vulnerabilities and report at least the critical ones. The patch management procedures “set deadlines for the installation of software and hardware patches and updates and escalation procedures in case those deadlines cannot be met”: the regulation gives no deadline of its own. The article is addressed to financial entities. The generated policy says nothing about DORA, even where you select it, and scans once a month, so a supplier whose customers ask for the weekly scan adds it.
UK GDPRArticle 32(1)Appropriate technical and organisational measures to ensure a level of security appropriate to the risk, including, as appropriate, “a process for regularly testing, assessing and evaluating the effectiveness of technical and organisational measures for ensuring the security of the processing”. The paragraph does not name scanning, security updates or penetration testing, and gives no interval.
CSA CAIQ v4.0.2TVM-01, TVM-03, TVM-06, TVM-07 and TVM-08The questions ask whether policies and procedures to identify, report and prioritise the remediation of vulnerabilities are established, documented, approved and reviewed at least annually (TVM-01); whether processes enable scheduled and emergency responses to vulnerability identifications, based on the identified risk (TVM-03); whether there is periodic, independent, third-party penetration testing (TVM-06); whether vulnerabilities are detected on organisationally managed assets at least monthly (TVM-07); and whether remediation is prioritised using a risk-based model from an industry-recognised framework (TVM-08). None asks for a number of days. The generated policy has a scan once a month, which is what TVM-07 asks about, only where you run infrastructure or manage systems for customers. TVM-06 asks about a penetration test: the policy takes the results of one in as vulnerabilities and does not require you to have one. CSA released CAIQ v4.1 in January 2026; its wording was not read for this page.
HECVAT 4PPPR-01, CHNG-07, CHNG-08, APPL-03 and VULN-01 to VULN-06“Do you have a documented patch management process?” (PPPR-01). “Do you have policy and procedure, currently implemented, managing how critical patches are applied to all systems and applications?” (CHNG-07). “Have you implemented policies and procedures that guide how security risks are mitigated until patches can be applied?” (CHNG-08). APPL-03 asks whether only currently supported operating systems, software and libraries are used. The six Vulnerability Management questions ask, among other things, whether systems are regularly scanned externally (VULN-06), whether you will give the institution your scan results (VULN-02) and let it run its own tests (VULN-03), and whether a third party assessed your security in the last year (VULN-04). No question asks for a number of days. The generated policy says nothing on VULN-02 to VULN-04, which are for your contract.
CISA Known Exploited Vulnerabilities catalogue (US)BOD 22-01 (revoked) and BOD 26-04The catalogue lists vulnerabilities that have a CVE ID, reliable evidence of active exploitation in the wild and a clear remediation action. Binding Operational Directive 22-01 created it and gave federal agencies two weeks or six months to remediate. CISA’s page for that directive is marked revoked, carries the date 10 June 2026 and says the directive is superseded by BOD 26-04. CISA’s page on the catalogue says federal civilian executive branch agencies are required to remediate catalogued vulnerabilities within prescribed timeframes under BOD 26-04, and that other organisations are not bound by it but are strongly recommended to prioritise them. The generated policy speaks of a vulnerability “known to be used in real attacks” and names no catalogue; decide which source you will use to know that.
CVSS v4.0 (FIRST)Qualitative severity rating scaleThe specification maps scores to ratings: Low 0.1 to 3.9, Medium 4.0 to 6.9, High 7.0 to 8.9 and Critical 9.0 to 10.0, with None at 0.0. It says the use of these ratings is optional. They are the four score ranges in the examples’ table. A base score measures how severe a vulnerability is, which is why the examples add a rule for one known to be used in real attacks. The generated policy gives no version of CVSS.

What customers will ask about it

When you sell to other businesses, their security questionnaires and audits ask about this early. Once it is in place, you can answer questions like these with confidence:

  • Do you have a documented patch management process?
  • Do you have a policy and procedure, currently implemented, managing how critical patches are applied to all systems and applications?
  • Have you implemented policies and procedures that guide how security risks are mitigated until patches can be applied?
  • Are your systems and applications regularly scanned externally for vulnerabilities?
  • Are only currently supported operating systems, software and libraries used by the systems that will have access to our data?
  • Are vulnerabilities detected on the assets you manage at least monthly?
  • Is vulnerability remediation prioritised using a risk-based model from an industry-recognised framework?
  • Are your vulnerability management policies and procedures reviewed and updated at least annually?

Vulnerability and Patch Management Policy examples

Each example below was produced by this generator for a fictional organisation, so you can see how the policy changes with size, sector and regulation. They are samples, not policies of real companies.

OrganisationOwnerApproved byWhat’s different
Seed-stage B2B SaaS startupCTOCEOThe CTO keeps the policy and the CEO approves it. It is the only example that gives a Critical vulnerability 14 days, because the company has 50 or fewer people, and the only one with no Managers bullet. The scope names servers, cloud accounts and other infrastructure and the software the company builds, so section 3 has both the scan at least once a month and the check of each change to that software, section 5 says when the time starts for a vulnerability in a component, and section 8 treats a component that is no longer maintained as unsupported software.
MSP serving defense and public sectorCISOCEOThe CISO keeps the policy and the CEO approves it, and a Critical vulnerability has 7 days. It is the only example whose scope and scan name network equipment, because the company runs systems in the cloud and on its own premises, and the only one with the systems it manages for customers: a bullet in section 3 scans them at least once a month, unless the customer’s contract says who scans them or how often, and a bullet in section 5 says the customer’s contract applies to such a system where it sets a different time or requires the customer’s agreement before a fix, and that the customer is told of each Critical or High vulnerability within 2 working days. The company builds no software, so the words “source control” and “component” do not appear. The profile selects CMMC, and the policy does not name it.
Multinational enterpriseCISOCEOThe CISO keeps the policy and the CEO approves it, a Critical vulnerability has 7 days, and managers have a bullet of their own. Like the seed-stage example it has the rules for infrastructure in the cloud and for software the company builds, and apart from the roles, the Managers bullet and the 7 days the two documents are the same, word for word. At 3,000 people the duties still sit with one role. Most are written as something the CISO makes sure is done, and a person the CISO has named in writing may rate a vulnerability, decide on a temporary measure where no update exists yet, decide whether to limit the use of a supplier’s service, or approve an exception for a Medium or Low vulnerability. An exception for a Critical or High one is approved by the CISO, and one for a Critical vulnerability also needs the written agreement of the CEO or of a person the CEO has named in writing. Nobody approves an exception they asked for: where the CISO asks for one, the CEO or a person the CEO has named in writing approves it instead.

[Company] Vulnerability and Patch Management Policy

  • Version: 1.0
  • Owner: CTO
  • Approved by: CEO
  • Effective date: [Effective date]
  • Next review date: [Review date]

4. Severity and Time to Fix

Every vulnerability is given one of four severity ratings, and its rating sets the time within which it must be fixed.

SeverityWhat it meansFixed within
CriticalA CVSS base score of 9.0 to 10.0, or a rating of critical from the supplier14 days
HighA CVSS base score of 7.0 to 8.9, or a rating of high from the supplier30 days
MediumA CVSS base score of 4.0 to 6.9, or a rating of medium or moderate from the supplier90 days
LowA CVSS base score of 0.1 to 3.9, or a rating of low from the supplier180 days

CVSS is the Common Vulnerability Scoring System, a published way of scoring how severe a vulnerability is, from 0 to 10. [Company] uses the base score published for the vulnerability. Where the base score and the supplier's rating give different ratings, the higher rating applies. A vulnerability that has neither, such as a setting that is not secure, is rated by the CTO or a person the CTO has named in writing, and is treated as High until it is rated.

A vulnerability that is known to be used in real attacks is rated Critical where the affected system can be reached from the internet, and no lower than High in every other case.

The CTO, or a person the CTO has named in writing, may raise a rating, and may lower it by one level where the affected system cannot be reached from the internet and holds no confidential information. The reason goes in the vulnerability record. A rating that the paragraph above sets is never lowered.

A Critical vulnerability in a system that can be reached from the internet is fixed, or protected by a temporary measure, within 2 working days of the day its time starts. A temporary measure does not stop the time, and the vulnerability is still fixed within the time the table gives.

5. Counting the Time

The time that the table in section 4 gives is counted in this way.

  • For a vulnerability that a supplier's security update fixes, the time starts on the day the supplier releases the update or on the day [Company] finds the vulnerability, whichever is later.
  • For a vulnerability in the software that [Company] builds, the time starts on the day [Company] finds it. Where the vulnerability is in a component that the software uses, the time starts on the day a version of the component that fixes it is released or on the day [Company] finds the vulnerability, whichever is later. Until that version is released, the component is treated as software whose supplier has not yet released a security update.
  • For a setting that is not secure, and for any other vulnerability that [Company] can fix without a security update from a supplier, the time starts on the day [Company] finds it.
  • Where a supplier has not yet released a security update for a Critical or High vulnerability, the CTO, or a person the CTO has named in writing, decides within 2 working days of the day it was found whether a temporary measure is put in place until the update is released, and the decision goes in the vulnerability record. Where the vulnerability is Critical and the affected system can be reached from the internet, a temporary measure is always put in place within those 2 working days.
  • Where a rating is raised, the time for the new rating starts on the day it was raised, but the vulnerability is never due later than it was before. Where a rating is lowered, the time for the new rating is counted from the day the time first started.
  • Where two times in this policy apply to the same vulnerability, the earlier one applies. Where a contract sets a shorter time than this policy for a system, the contract's time applies to that system.
  • A time given in days counts every day of the week. A time given in working days leaves out weekends and public holidays.
  • A vulnerability is fixed on the day the fix is made. Its vulnerability record is closed only when a check, such as a repeat scan, has confirmed that the vulnerability is gone. Where the check shows that the vulnerability is still there, it has not been fixed and its time carries on from the day it first started.

9. Exceptions to the Time to Fix

Where a vulnerability cannot be fixed within its time, the member of staff assigned it asks for an exception before the time runs out, and for a renewal before the exception ends. An exception does not fix the vulnerability. It sets a later date by which the vulnerability must be fixed and the temporary measure that protects [Company] until then.

  • A request for an exception gives the reason the fix cannot be made in time, the temporary measure that is or will be in place, and the date by which the vulnerability will be fixed. A request made after the time has run out also says why it was not made before then.
  • An exception is given only where the fix is not yet possible: no fix exists, the fix would break something that [Company] depends on, the system cannot be interrupted before a known date, or unsupported software or an unsupported device cannot be replaced before a known date. Other work taking priority is not a reason for an exception.
  • The CTO approves each exception in writing. For a Medium or Low vulnerability, a person the CTO has named in writing may approve it instead.
  • An exception for a Critical vulnerability also needs the written agreement of the CEO, or of a person the CEO has named in writing.
  • Nobody approves an exception that they asked for. Where the CTO is the one who asks for an exception, the CEO, or a person the CEO has named in writing, approves it instead.
  • An exception ends on the date it gives. That date is no later than 30 days after the exception is approved for a Critical vulnerability, 3 months for a High vulnerability and 12 months for a Medium or Low vulnerability. An exception is renewed only in the same way, and the request to renew it says why the vulnerability cannot be fixed by the earlier date.
  • An exception for a Critical or High vulnerability is recorded as a risk in [Company]'s risk register for as long as it lasts.
  • When an exception ends and the vulnerability has not been fixed, the vulnerability is overdue.

[Company] Vulnerability and Patch Management Policy

  • Version: 1.0
  • Owner: CTO
  • Approved by: CEO
  • Effective date: [Effective date]
  • Next review date: [Review date]

1. Purpose and Scope

This policy sets how [Company] finds vulnerabilities in the systems, software and devices it relies on, how it rates them, how quickly each must be fixed, how security updates are installed and how an exception is approved when a fix cannot be made in time. It sits beneath [Company]'s information security policy.

This policy covers every system, service and device that [Company] uses for its work or that holds its information, and the software on them: the laptops, phones, tablets and other devices that staff use; the servers, cloud accounts and other infrastructure that [Company] runs; the software that [Company] builds and the components that software uses; and the services that suppliers run for [Company]. Where a supplier runs a service, [Company] cannot itself fix the parts that the supplier runs, and section 7 sets what [Company] does about such a service.

This policy applies to everyone who is given access to [Company]'s systems, accounts or information: employees, contractors and anyone else working on its behalf. This policy calls them staff.

  • Vulnerability: a weakness in software, in a device or in the way a system is set up that could be used to harm [Company]'s systems or information.
  • Security update: a change that a supplier releases to its software or device to fix a vulnerability, often called a patch.
  • Fix: a security update, a correction to software or to a setting, or the removal of the affected software or system, that removes the vulnerability.
  • Temporary measure: a step that makes a vulnerability harder to use until it is fixed, such as turning off the affected feature or blocking access to it. A temporary measure is not a fix.
  • Vulnerability record: the record of a vulnerability, which section 10 describes.
  • Overdue: not fixed within the time this policy gives for fixing it and not covered by an exception approved under section 9.

2. Roles and Responsibilities

  • The CTO: keeps this policy and reviews it under section 12; makes sure vulnerabilities are found under section 3, rated under section 4 and assigned to a member of staff to fix; approves exceptions under sections 9 and 12; and makes the review and the report that section 11 describes.
  • The CEO: approves this policy and each change to it under section 12; gives the agreement that section 9 requires for an exception for a Critical vulnerability; approves an exception that the CTO asks for, under sections 9 and 12; and receives the report that section 11 describes.
  • Staff assigned a vulnerability: fix it within the time that section 4 gives, record what was done in its vulnerability record under section 10, and tell the CTO as soon as it is clear that the time cannot be met.
  • All staff: install security updates on the devices they use for [Company]'s work as section 6 requires, and report anything that looks like a vulnerability to the CTO as soon as they notice it.

3. Finding Vulnerabilities

  • The CTO makes sure that [Company] receives the security notices published by the suppliers of the systems, software and services it relies on, and that each notice is read within 2 working days to see whether it affects [Company].
  • At least once a month, and after any significant change to them, [Company] scans the servers, cloud accounts and other infrastructure that it runs with an automated tool that looks for known vulnerabilities and for settings that are not secure. At least once a month, [Company] also scans from outside its own network each system that can be reached from the internet. Where the tool is able to sign in to a system, the scan is made signed in.
  • [Company] must check each change to the software it builds, with an automated tool, for known vulnerabilities in its code and in the components it uses, before the change is released. The source control system that holds [Company]'s software must be set to alert [Company] when a vulnerability is published in a component that the software uses.
  • The CTO makes sure that the security settings of each service that a supplier runs for [Company], and that holds its confidential information, are checked when the service is first set up and at least every 12 months.
  • Where [Company] has a penetration test or another security test carried out, each weakness the test reports is recorded and rated as a vulnerability under this policy.
  • Anyone who finds or is told of a possible vulnerability, including one reported by a person outside [Company], passes it to the CTO as soon as they can. The CTO makes sure each report is looked into and, where it is a vulnerability, recorded.
  • The day a vulnerability was found is the day a scan, a test or a report first showed that it affects [Company], or the day [Company] received the supplier's notice of it, whichever is earlier.

4. Severity and Time to Fix

Every vulnerability is given one of four severity ratings, and its rating sets the time within which it must be fixed.

SeverityWhat it meansFixed within
CriticalA CVSS base score of 9.0 to 10.0, or a rating of critical from the supplier14 days
HighA CVSS base score of 7.0 to 8.9, or a rating of high from the supplier30 days
MediumA CVSS base score of 4.0 to 6.9, or a rating of medium or moderate from the supplier90 days
LowA CVSS base score of 0.1 to 3.9, or a rating of low from the supplier180 days

CVSS is the Common Vulnerability Scoring System, a published way of scoring how severe a vulnerability is, from 0 to 10. [Company] uses the base score published for the vulnerability. Where the base score and the supplier's rating give different ratings, the higher rating applies. A vulnerability that has neither, such as a setting that is not secure, is rated by the CTO or a person the CTO has named in writing, and is treated as High until it is rated.

A vulnerability that is known to be used in real attacks is rated Critical where the affected system can be reached from the internet, and no lower than High in every other case.

The CTO, or a person the CTO has named in writing, may raise a rating, and may lower it by one level where the affected system cannot be reached from the internet and holds no confidential information. The reason goes in the vulnerability record. A rating that the paragraph above sets is never lowered.

A Critical vulnerability in a system that can be reached from the internet is fixed, or protected by a temporary measure, within 2 working days of the day its time starts. A temporary measure does not stop the time, and the vulnerability is still fixed within the time the table gives.

5. Counting the Time

The time that the table in section 4 gives is counted in this way.

  • For a vulnerability that a supplier's security update fixes, the time starts on the day the supplier releases the update or on the day [Company] finds the vulnerability, whichever is later.
  • For a vulnerability in the software that [Company] builds, the time starts on the day [Company] finds it. Where the vulnerability is in a component that the software uses, the time starts on the day a version of the component that fixes it is released or on the day [Company] finds the vulnerability, whichever is later. Until that version is released, the component is treated as software whose supplier has not yet released a security update.
  • For a setting that is not secure, and for any other vulnerability that [Company] can fix without a security update from a supplier, the time starts on the day [Company] finds it.
  • Where a supplier has not yet released a security update for a Critical or High vulnerability, the CTO, or a person the CTO has named in writing, decides within 2 working days of the day it was found whether a temporary measure is put in place until the update is released, and the decision goes in the vulnerability record. Where the vulnerability is Critical and the affected system can be reached from the internet, a temporary measure is always put in place within those 2 working days.
  • Where a rating is raised, the time for the new rating starts on the day it was raised, but the vulnerability is never due later than it was before. Where a rating is lowered, the time for the new rating is counted from the day the time first started.
  • Where two times in this policy apply to the same vulnerability, the earlier one applies. Where a contract sets a shorter time than this policy for a system, the contract's time applies to that system.
  • A time given in days counts every day of the week. A time given in working days leaves out weekends and public holidays.
  • A vulnerability is fixed on the day the fix is made. Its vulnerability record is closed only when a check, such as a repeat scan, has confirmed that the vulnerability is gone. Where the check shows that the vulnerability is still there, it has not been fixed and its time carries on from the day it first started.

6. Installing Security Updates and Making Fixes

  • Staff must install security updates for the operating system and applications of each laptop, phone, tablet or other device they use for [Company]'s work within 14 days of their release, whatever the severity of the vulnerabilities they fix.
  • [Company] turns on automatic updates wherever a system, an application or a device offers them, unless the CTO has recorded a reason to install its updates in another way.
  • [Company] takes a security update only from the supplier of the software or device, or from a source that the supplier names.
  • Installing a security update or making another fix is a change. Where [Company]'s rules for change management cover the system, the fix is tested, reviewed, approved and recorded as those rules require, and this policy sets how soon it must be made.
  • Where a fix cannot wait for the review and approval that [Company]'s rules for change management would otherwise require, it is made in the way those rules allow for a change that cannot wait.
  • Where a security update cannot be installed without breaking something that [Company] depends on, the member of staff assigned the vulnerability tells the CTO, and the vulnerability is fixed in another way or has an exception under section 9 before its time runs out.
  • Where there are signs that a vulnerability has been used against [Company], it is a security incident and is handled under [Company]'s incident response plan. The vulnerability is still fixed under this policy.

7. Systems and Services That Suppliers Run

Where a supplier runs a system or service for [Company], the supplier fixes the parts it runs, and the times in section 4 do not apply to the supplier. [Company] fixes the parts it controls within those times: the settings of the service, anything [Company] installs or runs on it, and any application of the service that is installed on [Company]'s devices.

  • Before [Company] starts to use a service that will hold its confidential information, the CTO makes sure [Company] knows how the supplier gives notice of vulnerabilities in the service.
  • Where [Company] learns of a Critical or High vulnerability in a service that a supplier runs for it, the CTO makes sure within 5 working days that the supplier is asked when it will be fixed, and the CTO, or a person the CTO has named in writing, decides whether [Company] limits its use of the service until then. The vulnerability and the decision go in a vulnerability record.
  • Where a supplier does not fix a Critical or High vulnerability in a time that the CTO judges reasonable, the CTO makes sure it is recorded as a risk in [Company]'s risk register.
  • Where a supplier maintains systems or devices on [Company]'s behalf, a named member of staff makes sure the supplier meets this policy on them.

8. Unsupported Software and Devices

  • Software or a device is unsupported when its supplier no longer releases security updates for it.
  • The CTO makes sure [Company] knows the date on which support ends for each operating system and for the other main software and devices it relies on, and that each is upgraded, replaced or removed before that date.
  • Software or a device that is still in use after its support ends is recorded as a High vulnerability found on the day support ended. It is upgraded, replaced or removed within the time that section 4 gives a High vulnerability, unless it has an exception under section 9.
  • An exception for unsupported software or an unsupported device is approved only where a temporary measure cuts it off from the internet and from every system that does not need to reach it.
  • A vulnerability that is later found in unsupported software or an unsupported device is rated under section 4 in its own right, and its time starts on the day it is found.
  • A component that [Company]'s software uses and that is no longer maintained is unsupported software under this section.

9. Exceptions to the Time to Fix

Where a vulnerability cannot be fixed within its time, the member of staff assigned it asks for an exception before the time runs out, and for a renewal before the exception ends. An exception does not fix the vulnerability. It sets a later date by which the vulnerability must be fixed and the temporary measure that protects [Company] until then.

  • A request for an exception gives the reason the fix cannot be made in time, the temporary measure that is or will be in place, and the date by which the vulnerability will be fixed. A request made after the time has run out also says why it was not made before then.
  • An exception is given only where the fix is not yet possible: no fix exists, the fix would break something that [Company] depends on, the system cannot be interrupted before a known date, or unsupported software or an unsupported device cannot be replaced before a known date. Other work taking priority is not a reason for an exception.
  • The CTO approves each exception in writing. For a Medium or Low vulnerability, a person the CTO has named in writing may approve it instead.
  • An exception for a Critical vulnerability also needs the written agreement of the CEO, or of a person the CEO has named in writing.
  • Nobody approves an exception that they asked for. Where the CTO is the one who asks for an exception, the CEO, or a person the CEO has named in writing, approves it instead.
  • An exception ends on the date it gives. That date is no later than 30 days after the exception is approved for a Critical vulnerability, 3 months for a High vulnerability and 12 months for a Medium or Low vulnerability. An exception is renewed only in the same way, and the request to renew it says why the vulnerability cannot be fixed by the earlier date.
  • An exception for a Critical or High vulnerability is recorded as a risk in [Company]'s risk register for as long as it lasts.
  • When an exception ends and the vulnerability has not been fixed, the vulnerability is overdue.

10. Vulnerability Records

Every vulnerability has a vulnerability record, which holds these seven things.

  • What and where: the vulnerability, and the system, software or device it affects.
  • Severity: its rating under section 4, with any change to the rating and the reason for it.
  • Dates: the day it was found, the day its time started and the day by which it must be fixed.
  • Assigned to: the member of staff responsible for fixing it.
  • Temporary measure: any temporary measure that was put in place, and the day it was.
  • Fix: what was done, the day the fix was made and how it was confirmed.
  • Exception: any exception under section 9, with its reason, its temporary measure, its end date and who approved it.

A vulnerability record may be kept in the tool that found the vulnerability, provided that it holds these seven things. [Company] keeps each vulnerability record, and the results of each scan and test, for at least 3 years.

11. Monitoring and Reporting

  • At least once a month, the CTO makes sure that every open vulnerability is looked at, and that each one that is overdue, or will be due within the month, has a member of staff acting on it.
  • Within 5 working days of a vulnerability becoming overdue, the CTO makes sure that it is fixed or has an exception under section 9.
  • The CTO tells the CEO of each Critical vulnerability that becomes overdue, within 5 working days of the day it became overdue.
  • At least every 3 months, the CTO reports to the CEO the number of vulnerabilities open at each severity, the number overdue, the number fixed within their time and the number fixed after it since the last report, and each exception in force.
  • Where vulnerabilities of the same kind keep coming back, or are often overdue, the CTO looks for the cause and makes sure it is dealt with.

12. Other Exceptions, Breaches and Review

An exception to a rule in this policy other than a time to fix is requested from and approved in writing by the CTO, with the reason and any conditions recorded, and lasts no longer than 12 months unless it is renewed in the same way. Where the CTO is the one who asks for the exception, the CEO approves it instead.

Hiding a vulnerability, turning off automatic updates or a scan without the approval of the CTO, or writing in a vulnerability record something that the person writing it knows to be untrue, is a breach of this policy. A breach may lead to disciplinary action up to dismissal, in line with [Company]'s disciplinary process and the employment law of the country where the person works; for contractors and other non-employees it may lead to the engagement ending. Nobody is penalized for reporting a vulnerability, or a time that has been missed, in good faith.

The CTO reviews this policy at least every 12 months and after any significant change to [Company]'s systems, suppliers or ways of working, and each change to this policy is approved by the CEO.

[Company] Vulnerability and Patch Management Policy

  • Version: 1.0
  • Owner: CISO
  • Approved by: CEO
  • Effective date: [Effective date]
  • Next review date: [Review date]

4. Severity and Time to Fix

Every vulnerability is given one of four severity ratings, and its rating sets the time within which it must be fixed.

SeverityWhat it meansFixed within
CriticalA CVSS base score of 9.0 to 10.0, or a rating of critical from the supplier7 days
HighA CVSS base score of 7.0 to 8.9, or a rating of high from the supplier30 days
MediumA CVSS base score of 4.0 to 6.9, or a rating of medium or moderate from the supplier90 days
LowA CVSS base score of 0.1 to 3.9, or a rating of low from the supplier180 days

CVSS is the Common Vulnerability Scoring System, a published way of scoring how severe a vulnerability is, from 0 to 10. [Company] uses the base score published for the vulnerability. Where the base score and the supplier's rating give different ratings, the higher rating applies. A vulnerability that has neither, such as a setting that is not secure, is rated by the CISO or a person the CISO has named in writing, and is treated as High until it is rated.

A vulnerability that is known to be used in real attacks is rated Critical where the affected system can be reached from the internet, and no lower than High in every other case.

The CISO, or a person the CISO has named in writing, may raise a rating, and may lower it by one level where the affected system cannot be reached from the internet and holds no confidential information. The reason goes in the vulnerability record. A rating that the paragraph above sets is never lowered.

A Critical vulnerability in a system that can be reached from the internet is fixed, or protected by a temporary measure, within 2 working days of the day its time starts. A temporary measure does not stop the time, and the vulnerability is still fixed within the time the table gives.

5. Counting the Time

The time that the table in section 4 gives is counted in this way.

  • For a vulnerability that a supplier's security update fixes, the time starts on the day the supplier releases the update or on the day [Company] finds the vulnerability, whichever is later.
  • For a setting that is not secure, and for any other vulnerability that [Company] can fix without a security update from a supplier, the time starts on the day [Company] finds it.
  • Where a supplier has not yet released a security update for a Critical or High vulnerability, the CISO, or a person the CISO has named in writing, decides within 2 working days of the day it was found whether a temporary measure is put in place until the update is released, and the decision goes in the vulnerability record. Where the vulnerability is Critical and the affected system can be reached from the internet, a temporary measure is always put in place within those 2 working days.
  • Where a rating is raised, the time for the new rating starts on the day it was raised, but the vulnerability is never due later than it was before. Where a rating is lowered, the time for the new rating is counted from the day the time first started.
  • Where two times in this policy apply to the same vulnerability, the earlier one applies. Where a contract sets a shorter time than this policy for a system, the contract's time applies to that system.
  • A time given in days counts every day of the week. A time given in working days leaves out weekends and public holidays.
  • A vulnerability is fixed on the day the fix is made. Its vulnerability record is closed only when a check, such as a repeat scan, has confirmed that the vulnerability is gone. Where the check shows that the vulnerability is still there, it has not been fixed and its time carries on from the day it first started.
  • A vulnerability in a system that [Company] manages for a customer is found, rated, fixed and recorded under this policy. Where the contract with that customer sets a different time for such a system, whether shorter or longer than the time this policy gives, or requires the customer's agreement before a fix is made, the contract applies to that system. [Company] tells the customer of each Critical or High vulnerability it finds in such a system within 2 working days of the day it was found.

9. Exceptions to the Time to Fix

Where a vulnerability cannot be fixed within its time, the member of staff assigned it asks for an exception before the time runs out, and for a renewal before the exception ends. An exception does not fix the vulnerability. It sets a later date by which the vulnerability must be fixed and the temporary measure that protects [Company] until then.

  • A request for an exception gives the reason the fix cannot be made in time, the temporary measure that is or will be in place, and the date by which the vulnerability will be fixed. A request made after the time has run out also says why it was not made before then.
  • An exception is given only where the fix is not yet possible: no fix exists, the fix would break something that [Company] depends on, the system cannot be interrupted before a known date, or unsupported software or an unsupported device cannot be replaced before a known date. Other work taking priority is not a reason for an exception.
  • The CISO approves each exception in writing. For a Medium or Low vulnerability, a person the CISO has named in writing may approve it instead.
  • An exception for a Critical vulnerability also needs the written agreement of the CEO, or of a person the CEO has named in writing.
  • Nobody approves an exception that they asked for. Where the CISO is the one who asks for an exception, the CEO, or a person the CEO has named in writing, approves it instead.
  • An exception ends on the date it gives. That date is no later than 30 days after the exception is approved for a Critical vulnerability, 3 months for a High vulnerability and 12 months for a Medium or Low vulnerability. An exception is renewed only in the same way, and the request to renew it says why the vulnerability cannot be fixed by the earlier date.
  • An exception for a Critical or High vulnerability is recorded as a risk in [Company]'s risk register for as long as it lasts.
  • When an exception ends and the vulnerability has not been fixed, the vulnerability is overdue.

[Company] Vulnerability and Patch Management Policy

  • Version: 1.0
  • Owner: CISO
  • Approved by: CEO
  • Effective date: [Effective date]
  • Next review date: [Review date]

1. Purpose and Scope

This policy sets how [Company] finds vulnerabilities in the systems, software and devices it relies on, how it rates them, how quickly each must be fixed, how security updates are installed and how an exception is approved when a fix cannot be made in time. It sits beneath [Company]'s information security policy.

This policy covers every system, service and device that [Company] uses for its work or that holds its information, and the software on them: the laptops, phones, tablets and other devices that staff use; the servers, cloud accounts, network equipment and other infrastructure that [Company] runs; the systems that [Company] manages for its customers; and the services that suppliers run for [Company]. Where a supplier runs a service, [Company] cannot itself fix the parts that the supplier runs, and section 7 sets what [Company] does about such a service.

This policy applies to everyone who is given access to [Company]'s systems, accounts or information: employees, contractors and anyone else working on its behalf. This policy calls them staff.

  • Vulnerability: a weakness in software, in a device or in the way a system is set up that could be used to harm [Company]'s systems or information.
  • Security update: a change that a supplier releases to its software or device to fix a vulnerability, often called a patch.
  • Fix: a security update, a correction to software or to a setting, or the removal of the affected software or system, that removes the vulnerability.
  • Temporary measure: a step that makes a vulnerability harder to use until it is fixed, such as turning off the affected feature or blocking access to it. A temporary measure is not a fix.
  • Vulnerability record: the record of a vulnerability, which section 10 describes.
  • Overdue: not fixed within the time this policy gives for fixing it and not covered by an exception approved under section 9.

2. Roles and Responsibilities

  • The CISO: keeps this policy and reviews it under section 12; makes sure vulnerabilities are found under section 3, rated under section 4 and assigned to a member of staff to fix; approves exceptions under sections 9 and 12; and makes the review and the report that section 11 describes.
  • The CEO: approves this policy and each change to it under section 12; gives the agreement that section 9 requires for an exception for a Critical vulnerability; approves an exception that the CISO asks for, under sections 9 and 12; and receives the report that section 11 describes.
  • Staff assigned a vulnerability: fix it within the time that section 4 gives, record what was done in its vulnerability record under section 10, and tell the CISO as soon as it is clear that the time cannot be met.
  • Managers: make sure the vulnerabilities assigned to their teams are fixed on time, and that the devices their teams use are kept up to date as section 6 requires.
  • All staff: install security updates on the devices they use for [Company]'s work as section 6 requires, and report anything that looks like a vulnerability to the CISO as soon as they notice it.

3. Finding Vulnerabilities

  • The CISO makes sure that [Company] receives the security notices published by the suppliers of the systems, software and services it relies on, and that each notice is read within 2 working days to see whether it affects [Company].
  • At least once a month, and after any significant change to them, [Company] scans the servers, cloud accounts, network equipment and other infrastructure that it runs with an automated tool that looks for known vulnerabilities and for settings that are not secure. At least once a month, [Company] also scans from outside its own network each system that can be reached from the internet. Where the tool is able to sign in to a system, the scan is made signed in.
  • At least once a month, [Company] scans the systems that it manages for its customers with an automated tool that looks for known vulnerabilities and for settings that are not secure. Where the contract with a customer says who scans that customer's systems, or how often, the contract applies to those systems.
  • The CISO makes sure that the security settings of each service that a supplier runs for [Company], and that holds its confidential information, are checked when the service is first set up and at least every 12 months.
  • Where [Company] has a penetration test or another security test carried out, each weakness the test reports is recorded and rated as a vulnerability under this policy.
  • Anyone who finds or is told of a possible vulnerability, including one reported by a person outside [Company], passes it to the CISO as soon as they can. The CISO makes sure each report is looked into and, where it is a vulnerability, recorded.
  • The day a vulnerability was found is the day a scan, a test or a report first showed that it affects [Company], or the day [Company] received the supplier's notice of it, whichever is earlier.

4. Severity and Time to Fix

Every vulnerability is given one of four severity ratings, and its rating sets the time within which it must be fixed.

SeverityWhat it meansFixed within
CriticalA CVSS base score of 9.0 to 10.0, or a rating of critical from the supplier7 days
HighA CVSS base score of 7.0 to 8.9, or a rating of high from the supplier30 days
MediumA CVSS base score of 4.0 to 6.9, or a rating of medium or moderate from the supplier90 days
LowA CVSS base score of 0.1 to 3.9, or a rating of low from the supplier180 days

CVSS is the Common Vulnerability Scoring System, a published way of scoring how severe a vulnerability is, from 0 to 10. [Company] uses the base score published for the vulnerability. Where the base score and the supplier's rating give different ratings, the higher rating applies. A vulnerability that has neither, such as a setting that is not secure, is rated by the CISO or a person the CISO has named in writing, and is treated as High until it is rated.

A vulnerability that is known to be used in real attacks is rated Critical where the affected system can be reached from the internet, and no lower than High in every other case.

The CISO, or a person the CISO has named in writing, may raise a rating, and may lower it by one level where the affected system cannot be reached from the internet and holds no confidential information. The reason goes in the vulnerability record. A rating that the paragraph above sets is never lowered.

A Critical vulnerability in a system that can be reached from the internet is fixed, or protected by a temporary measure, within 2 working days of the day its time starts. A temporary measure does not stop the time, and the vulnerability is still fixed within the time the table gives.

5. Counting the Time

The time that the table in section 4 gives is counted in this way.

  • For a vulnerability that a supplier's security update fixes, the time starts on the day the supplier releases the update or on the day [Company] finds the vulnerability, whichever is later.
  • For a setting that is not secure, and for any other vulnerability that [Company] can fix without a security update from a supplier, the time starts on the day [Company] finds it.
  • Where a supplier has not yet released a security update for a Critical or High vulnerability, the CISO, or a person the CISO has named in writing, decides within 2 working days of the day it was found whether a temporary measure is put in place until the update is released, and the decision goes in the vulnerability record. Where the vulnerability is Critical and the affected system can be reached from the internet, a temporary measure is always put in place within those 2 working days.
  • Where a rating is raised, the time for the new rating starts on the day it was raised, but the vulnerability is never due later than it was before. Where a rating is lowered, the time for the new rating is counted from the day the time first started.
  • Where two times in this policy apply to the same vulnerability, the earlier one applies. Where a contract sets a shorter time than this policy for a system, the contract's time applies to that system.
  • A time given in days counts every day of the week. A time given in working days leaves out weekends and public holidays.
  • A vulnerability is fixed on the day the fix is made. Its vulnerability record is closed only when a check, such as a repeat scan, has confirmed that the vulnerability is gone. Where the check shows that the vulnerability is still there, it has not been fixed and its time carries on from the day it first started.
  • A vulnerability in a system that [Company] manages for a customer is found, rated, fixed and recorded under this policy. Where the contract with that customer sets a different time for such a system, whether shorter or longer than the time this policy gives, or requires the customer's agreement before a fix is made, the contract applies to that system. [Company] tells the customer of each Critical or High vulnerability it finds in such a system within 2 working days of the day it was found.

6. Installing Security Updates and Making Fixes

  • Staff must install security updates for the operating system and applications of each laptop, phone, tablet or other device they use for [Company]'s work within 14 days of their release, whatever the severity of the vulnerabilities they fix.
  • [Company] turns on automatic updates wherever a system, an application or a device offers them, unless the CISO has recorded a reason to install its updates in another way.
  • [Company] takes a security update only from the supplier of the software or device, or from a source that the supplier names.
  • Installing a security update or making another fix is a change. Where [Company]'s rules for change management cover the system, the fix is tested, reviewed, approved and recorded as those rules require, and this policy sets how soon it must be made.
  • Where a fix cannot wait for the review and approval that [Company]'s rules for change management would otherwise require, it is made in the way those rules allow for a change that cannot wait.
  • Where a security update cannot be installed without breaking something that [Company] depends on, the member of staff assigned the vulnerability tells the CISO, and the vulnerability is fixed in another way or has an exception under section 9 before its time runs out.
  • Where there are signs that a vulnerability has been used against [Company], it is a security incident and is handled under [Company]'s incident response plan. The vulnerability is still fixed under this policy.

7. Systems and Services That Suppliers Run

Where a supplier runs a system or service for [Company], the supplier fixes the parts it runs, and the times in section 4 do not apply to the supplier. [Company] fixes the parts it controls within those times: the settings of the service, anything [Company] installs or runs on it, and any application of the service that is installed on [Company]'s devices.

  • Before [Company] starts to use a service that will hold its confidential information, the CISO makes sure [Company] knows how the supplier gives notice of vulnerabilities in the service.
  • Where [Company] learns of a Critical or High vulnerability in a service that a supplier runs for it, the CISO makes sure within 5 working days that the supplier is asked when it will be fixed, and the CISO, or a person the CISO has named in writing, decides whether [Company] limits its use of the service until then. The vulnerability and the decision go in a vulnerability record.
  • Where a supplier does not fix a Critical or High vulnerability in a time that the CISO judges reasonable, the CISO makes sure it is recorded as a risk in [Company]'s risk register.
  • Where a supplier maintains systems or devices on [Company]'s behalf, a named member of staff makes sure the supplier meets this policy on them.

8. Unsupported Software and Devices

  • Software or a device is unsupported when its supplier no longer releases security updates for it.
  • The CISO makes sure [Company] knows the date on which support ends for each operating system and for the other main software and devices it relies on, and that each is upgraded, replaced or removed before that date.
  • Software or a device that is still in use after its support ends is recorded as a High vulnerability found on the day support ended. It is upgraded, replaced or removed within the time that section 4 gives a High vulnerability, unless it has an exception under section 9.
  • An exception for unsupported software or an unsupported device is approved only where a temporary measure cuts it off from the internet and from every system that does not need to reach it.
  • A vulnerability that is later found in unsupported software or an unsupported device is rated under section 4 in its own right, and its time starts on the day it is found.

9. Exceptions to the Time to Fix

Where a vulnerability cannot be fixed within its time, the member of staff assigned it asks for an exception before the time runs out, and for a renewal before the exception ends. An exception does not fix the vulnerability. It sets a later date by which the vulnerability must be fixed and the temporary measure that protects [Company] until then.

  • A request for an exception gives the reason the fix cannot be made in time, the temporary measure that is or will be in place, and the date by which the vulnerability will be fixed. A request made after the time has run out also says why it was not made before then.
  • An exception is given only where the fix is not yet possible: no fix exists, the fix would break something that [Company] depends on, the system cannot be interrupted before a known date, or unsupported software or an unsupported device cannot be replaced before a known date. Other work taking priority is not a reason for an exception.
  • The CISO approves each exception in writing. For a Medium or Low vulnerability, a person the CISO has named in writing may approve it instead.
  • An exception for a Critical vulnerability also needs the written agreement of the CEO, or of a person the CEO has named in writing.
  • Nobody approves an exception that they asked for. Where the CISO is the one who asks for an exception, the CEO, or a person the CEO has named in writing, approves it instead.
  • An exception ends on the date it gives. That date is no later than 30 days after the exception is approved for a Critical vulnerability, 3 months for a High vulnerability and 12 months for a Medium or Low vulnerability. An exception is renewed only in the same way, and the request to renew it says why the vulnerability cannot be fixed by the earlier date.
  • An exception for a Critical or High vulnerability is recorded as a risk in [Company]'s risk register for as long as it lasts.
  • When an exception ends and the vulnerability has not been fixed, the vulnerability is overdue.

10. Vulnerability Records

Every vulnerability has a vulnerability record, which holds these seven things.

  • What and where: the vulnerability, and the system, software or device it affects.
  • Severity: its rating under section 4, with any change to the rating and the reason for it.
  • Dates: the day it was found, the day its time started and the day by which it must be fixed.
  • Assigned to: the member of staff responsible for fixing it.
  • Temporary measure: any temporary measure that was put in place, and the day it was.
  • Fix: what was done, the day the fix was made and how it was confirmed.
  • Exception: any exception under section 9, with its reason, its temporary measure, its end date and who approved it.

A vulnerability record may be kept in the tool that found the vulnerability, provided that it holds these seven things. [Company] keeps each vulnerability record, and the results of each scan and test, for at least 3 years.

11. Monitoring and Reporting

  • At least once a month, the CISO makes sure that every open vulnerability is looked at, and that each one that is overdue, or will be due within the month, has a member of staff acting on it.
  • Within 5 working days of a vulnerability becoming overdue, the CISO makes sure that it is fixed or has an exception under section 9.
  • The CISO tells the CEO of each Critical vulnerability that becomes overdue, within 5 working days of the day it became overdue.
  • At least every 3 months, the CISO reports to the CEO the number of vulnerabilities open at each severity, the number overdue, the number fixed within their time and the number fixed after it since the last report, and each exception in force.
  • Where vulnerabilities of the same kind keep coming back, or are often overdue, the CISO looks for the cause and makes sure it is dealt with.

12. Other Exceptions, Breaches and Review

An exception to a rule in this policy other than a time to fix is requested from and approved in writing by the CISO, with the reason and any conditions recorded, and lasts no longer than 12 months unless it is renewed in the same way. Where the CISO is the one who asks for the exception, the CEO approves it instead.

Hiding a vulnerability, turning off automatic updates or a scan without the approval of the CISO, or writing in a vulnerability record something that the person writing it knows to be untrue, is a breach of this policy. A breach may lead to disciplinary action up to dismissal, in line with [Company]'s disciplinary process and the employment law of the country where the person works; for contractors and other non-employees it may lead to the engagement ending. Nobody is penalized for reporting a vulnerability, or a time that has been missed, in good faith.

The CISO reviews this policy at least every 12 months and after any significant change to [Company]'s systems, suppliers or ways of working, and each change to this policy is approved by the CEO.

[Company] Vulnerability and Patch Management Policy

  • Version: 1.0
  • Owner: CISO
  • Approved by: CEO
  • Effective date: [Effective date]
  • Next review date: [Review date]

4. Severity and Time to Fix

Every vulnerability is given one of four severity ratings, and its rating sets the time within which it must be fixed.

SeverityWhat it meansFixed within
CriticalA CVSS base score of 9.0 to 10.0, or a rating of critical from the supplier7 days
HighA CVSS base score of 7.0 to 8.9, or a rating of high from the supplier30 days
MediumA CVSS base score of 4.0 to 6.9, or a rating of medium or moderate from the supplier90 days
LowA CVSS base score of 0.1 to 3.9, or a rating of low from the supplier180 days

CVSS is the Common Vulnerability Scoring System, a published way of scoring how severe a vulnerability is, from 0 to 10. [Company] uses the base score published for the vulnerability. Where the base score and the supplier's rating give different ratings, the higher rating applies. A vulnerability that has neither, such as a setting that is not secure, is rated by the CISO or a person the CISO has named in writing, and is treated as High until it is rated.

A vulnerability that is known to be used in real attacks is rated Critical where the affected system can be reached from the internet, and no lower than High in every other case.

The CISO, or a person the CISO has named in writing, may raise a rating, and may lower it by one level where the affected system cannot be reached from the internet and holds no confidential information. The reason goes in the vulnerability record. A rating that the paragraph above sets is never lowered.

A Critical vulnerability in a system that can be reached from the internet is fixed, or protected by a temporary measure, within 2 working days of the day its time starts. A temporary measure does not stop the time, and the vulnerability is still fixed within the time the table gives.

5. Counting the Time

The time that the table in section 4 gives is counted in this way.

  • For a vulnerability that a supplier's security update fixes, the time starts on the day the supplier releases the update or on the day [Company] finds the vulnerability, whichever is later.
  • For a vulnerability in the software that [Company] builds, the time starts on the day [Company] finds it. Where the vulnerability is in a component that the software uses, the time starts on the day a version of the component that fixes it is released or on the day [Company] finds the vulnerability, whichever is later. Until that version is released, the component is treated as software whose supplier has not yet released a security update.
  • For a setting that is not secure, and for any other vulnerability that [Company] can fix without a security update from a supplier, the time starts on the day [Company] finds it.
  • Where a supplier has not yet released a security update for a Critical or High vulnerability, the CISO, or a person the CISO has named in writing, decides within 2 working days of the day it was found whether a temporary measure is put in place until the update is released, and the decision goes in the vulnerability record. Where the vulnerability is Critical and the affected system can be reached from the internet, a temporary measure is always put in place within those 2 working days.
  • Where a rating is raised, the time for the new rating starts on the day it was raised, but the vulnerability is never due later than it was before. Where a rating is lowered, the time for the new rating is counted from the day the time first started.
  • Where two times in this policy apply to the same vulnerability, the earlier one applies. Where a contract sets a shorter time than this policy for a system, the contract's time applies to that system.
  • A time given in days counts every day of the week. A time given in working days leaves out weekends and public holidays.
  • A vulnerability is fixed on the day the fix is made. Its vulnerability record is closed only when a check, such as a repeat scan, has confirmed that the vulnerability is gone. Where the check shows that the vulnerability is still there, it has not been fixed and its time carries on from the day it first started.

9. Exceptions to the Time to Fix

Where a vulnerability cannot be fixed within its time, the member of staff assigned it asks for an exception before the time runs out, and for a renewal before the exception ends. An exception does not fix the vulnerability. It sets a later date by which the vulnerability must be fixed and the temporary measure that protects [Company] until then.

  • A request for an exception gives the reason the fix cannot be made in time, the temporary measure that is or will be in place, and the date by which the vulnerability will be fixed. A request made after the time has run out also says why it was not made before then.
  • An exception is given only where the fix is not yet possible: no fix exists, the fix would break something that [Company] depends on, the system cannot be interrupted before a known date, or unsupported software or an unsupported device cannot be replaced before a known date. Other work taking priority is not a reason for an exception.
  • The CISO approves each exception in writing. For a Medium or Low vulnerability, a person the CISO has named in writing may approve it instead.
  • An exception for a Critical vulnerability also needs the written agreement of the CEO, or of a person the CEO has named in writing.
  • Nobody approves an exception that they asked for. Where the CISO is the one who asks for an exception, the CEO, or a person the CEO has named in writing, approves it instead.
  • An exception ends on the date it gives. That date is no later than 30 days after the exception is approved for a Critical vulnerability, 3 months for a High vulnerability and 12 months for a Medium or Low vulnerability. An exception is renewed only in the same way, and the request to renew it says why the vulnerability cannot be fixed by the earlier date.
  • An exception for a Critical or High vulnerability is recorded as a risk in [Company]'s risk register for as long as it lasts.
  • When an exception ends and the vulnerability has not been fixed, the vulnerability is overdue.

[Company] Vulnerability and Patch Management Policy

  • Version: 1.0
  • Owner: CISO
  • Approved by: CEO
  • Effective date: [Effective date]
  • Next review date: [Review date]

1. Purpose and Scope

This policy sets how [Company] finds vulnerabilities in the systems, software and devices it relies on, how it rates them, how quickly each must be fixed, how security updates are installed and how an exception is approved when a fix cannot be made in time. It sits beneath [Company]'s information security policy.

This policy covers every system, service and device that [Company] uses for its work or that holds its information, and the software on them: the laptops, phones, tablets and other devices that staff use; the servers, cloud accounts and other infrastructure that [Company] runs; the software that [Company] builds and the components that software uses; and the services that suppliers run for [Company]. Where a supplier runs a service, [Company] cannot itself fix the parts that the supplier runs, and section 7 sets what [Company] does about such a service.

This policy applies to everyone who is given access to [Company]'s systems, accounts or information: employees, contractors and anyone else working on its behalf. This policy calls them staff.

  • Vulnerability: a weakness in software, in a device or in the way a system is set up that could be used to harm [Company]'s systems or information.
  • Security update: a change that a supplier releases to its software or device to fix a vulnerability, often called a patch.
  • Fix: a security update, a correction to software or to a setting, or the removal of the affected software or system, that removes the vulnerability.
  • Temporary measure: a step that makes a vulnerability harder to use until it is fixed, such as turning off the affected feature or blocking access to it. A temporary measure is not a fix.
  • Vulnerability record: the record of a vulnerability, which section 10 describes.
  • Overdue: not fixed within the time this policy gives for fixing it and not covered by an exception approved under section 9.

2. Roles and Responsibilities

  • The CISO: keeps this policy and reviews it under section 12; makes sure vulnerabilities are found under section 3, rated under section 4 and assigned to a member of staff to fix; approves exceptions under sections 9 and 12; and makes the review and the report that section 11 describes.
  • The CEO: approves this policy and each change to it under section 12; gives the agreement that section 9 requires for an exception for a Critical vulnerability; approves an exception that the CISO asks for, under sections 9 and 12; and receives the report that section 11 describes.
  • Staff assigned a vulnerability: fix it within the time that section 4 gives, record what was done in its vulnerability record under section 10, and tell the CISO as soon as it is clear that the time cannot be met.
  • Managers: make sure the vulnerabilities assigned to their teams are fixed on time, and that the devices their teams use are kept up to date as section 6 requires.
  • All staff: install security updates on the devices they use for [Company]'s work as section 6 requires, and report anything that looks like a vulnerability to the CISO as soon as they notice it.

3. Finding Vulnerabilities

  • The CISO makes sure that [Company] receives the security notices published by the suppliers of the systems, software and services it relies on, and that each notice is read within 2 working days to see whether it affects [Company].
  • At least once a month, and after any significant change to them, [Company] scans the servers, cloud accounts and other infrastructure that it runs with an automated tool that looks for known vulnerabilities and for settings that are not secure. At least once a month, [Company] also scans from outside its own network each system that can be reached from the internet. Where the tool is able to sign in to a system, the scan is made signed in.
  • [Company] must check each change to the software it builds, with an automated tool, for known vulnerabilities in its code and in the components it uses, before the change is released. The source control system that holds [Company]'s software must be set to alert [Company] when a vulnerability is published in a component that the software uses.
  • The CISO makes sure that the security settings of each service that a supplier runs for [Company], and that holds its confidential information, are checked when the service is first set up and at least every 12 months.
  • Where [Company] has a penetration test or another security test carried out, each weakness the test reports is recorded and rated as a vulnerability under this policy.
  • Anyone who finds or is told of a possible vulnerability, including one reported by a person outside [Company], passes it to the CISO as soon as they can. The CISO makes sure each report is looked into and, where it is a vulnerability, recorded.
  • The day a vulnerability was found is the day a scan, a test or a report first showed that it affects [Company], or the day [Company] received the supplier's notice of it, whichever is earlier.

4. Severity and Time to Fix

Every vulnerability is given one of four severity ratings, and its rating sets the time within which it must be fixed.

SeverityWhat it meansFixed within
CriticalA CVSS base score of 9.0 to 10.0, or a rating of critical from the supplier7 days
HighA CVSS base score of 7.0 to 8.9, or a rating of high from the supplier30 days
MediumA CVSS base score of 4.0 to 6.9, or a rating of medium or moderate from the supplier90 days
LowA CVSS base score of 0.1 to 3.9, or a rating of low from the supplier180 days

CVSS is the Common Vulnerability Scoring System, a published way of scoring how severe a vulnerability is, from 0 to 10. [Company] uses the base score published for the vulnerability. Where the base score and the supplier's rating give different ratings, the higher rating applies. A vulnerability that has neither, such as a setting that is not secure, is rated by the CISO or a person the CISO has named in writing, and is treated as High until it is rated.

A vulnerability that is known to be used in real attacks is rated Critical where the affected system can be reached from the internet, and no lower than High in every other case.

The CISO, or a person the CISO has named in writing, may raise a rating, and may lower it by one level where the affected system cannot be reached from the internet and holds no confidential information. The reason goes in the vulnerability record. A rating that the paragraph above sets is never lowered.

A Critical vulnerability in a system that can be reached from the internet is fixed, or protected by a temporary measure, within 2 working days of the day its time starts. A temporary measure does not stop the time, and the vulnerability is still fixed within the time the table gives.

5. Counting the Time

The time that the table in section 4 gives is counted in this way.

  • For a vulnerability that a supplier's security update fixes, the time starts on the day the supplier releases the update or on the day [Company] finds the vulnerability, whichever is later.
  • For a vulnerability in the software that [Company] builds, the time starts on the day [Company] finds it. Where the vulnerability is in a component that the software uses, the time starts on the day a version of the component that fixes it is released or on the day [Company] finds the vulnerability, whichever is later. Until that version is released, the component is treated as software whose supplier has not yet released a security update.
  • For a setting that is not secure, and for any other vulnerability that [Company] can fix without a security update from a supplier, the time starts on the day [Company] finds it.
  • Where a supplier has not yet released a security update for a Critical or High vulnerability, the CISO, or a person the CISO has named in writing, decides within 2 working days of the day it was found whether a temporary measure is put in place until the update is released, and the decision goes in the vulnerability record. Where the vulnerability is Critical and the affected system can be reached from the internet, a temporary measure is always put in place within those 2 working days.
  • Where a rating is raised, the time for the new rating starts on the day it was raised, but the vulnerability is never due later than it was before. Where a rating is lowered, the time for the new rating is counted from the day the time first started.
  • Where two times in this policy apply to the same vulnerability, the earlier one applies. Where a contract sets a shorter time than this policy for a system, the contract's time applies to that system.
  • A time given in days counts every day of the week. A time given in working days leaves out weekends and public holidays.
  • A vulnerability is fixed on the day the fix is made. Its vulnerability record is closed only when a check, such as a repeat scan, has confirmed that the vulnerability is gone. Where the check shows that the vulnerability is still there, it has not been fixed and its time carries on from the day it first started.

6. Installing Security Updates and Making Fixes

  • Staff must install security updates for the operating system and applications of each laptop, phone, tablet or other device they use for [Company]'s work within 14 days of their release, whatever the severity of the vulnerabilities they fix.
  • [Company] turns on automatic updates wherever a system, an application or a device offers them, unless the CISO has recorded a reason to install its updates in another way.
  • [Company] takes a security update only from the supplier of the software or device, or from a source that the supplier names.
  • Installing a security update or making another fix is a change. Where [Company]'s rules for change management cover the system, the fix is tested, reviewed, approved and recorded as those rules require, and this policy sets how soon it must be made.
  • Where a fix cannot wait for the review and approval that [Company]'s rules for change management would otherwise require, it is made in the way those rules allow for a change that cannot wait.
  • Where a security update cannot be installed without breaking something that [Company] depends on, the member of staff assigned the vulnerability tells the CISO, and the vulnerability is fixed in another way or has an exception under section 9 before its time runs out.
  • Where there are signs that a vulnerability has been used against [Company], it is a security incident and is handled under [Company]'s incident response plan. The vulnerability is still fixed under this policy.

7. Systems and Services That Suppliers Run

Where a supplier runs a system or service for [Company], the supplier fixes the parts it runs, and the times in section 4 do not apply to the supplier. [Company] fixes the parts it controls within those times: the settings of the service, anything [Company] installs or runs on it, and any application of the service that is installed on [Company]'s devices.

  • Before [Company] starts to use a service that will hold its confidential information, the CISO makes sure [Company] knows how the supplier gives notice of vulnerabilities in the service.
  • Where [Company] learns of a Critical or High vulnerability in a service that a supplier runs for it, the CISO makes sure within 5 working days that the supplier is asked when it will be fixed, and the CISO, or a person the CISO has named in writing, decides whether [Company] limits its use of the service until then. The vulnerability and the decision go in a vulnerability record.
  • Where a supplier does not fix a Critical or High vulnerability in a time that the CISO judges reasonable, the CISO makes sure it is recorded as a risk in [Company]'s risk register.
  • Where a supplier maintains systems or devices on [Company]'s behalf, a named member of staff makes sure the supplier meets this policy on them.

8. Unsupported Software and Devices

  • Software or a device is unsupported when its supplier no longer releases security updates for it.
  • The CISO makes sure [Company] knows the date on which support ends for each operating system and for the other main software and devices it relies on, and that each is upgraded, replaced or removed before that date.
  • Software or a device that is still in use after its support ends is recorded as a High vulnerability found on the day support ended. It is upgraded, replaced or removed within the time that section 4 gives a High vulnerability, unless it has an exception under section 9.
  • An exception for unsupported software or an unsupported device is approved only where a temporary measure cuts it off from the internet and from every system that does not need to reach it.
  • A vulnerability that is later found in unsupported software or an unsupported device is rated under section 4 in its own right, and its time starts on the day it is found.
  • A component that [Company]'s software uses and that is no longer maintained is unsupported software under this section.

9. Exceptions to the Time to Fix

Where a vulnerability cannot be fixed within its time, the member of staff assigned it asks for an exception before the time runs out, and for a renewal before the exception ends. An exception does not fix the vulnerability. It sets a later date by which the vulnerability must be fixed and the temporary measure that protects [Company] until then.

  • A request for an exception gives the reason the fix cannot be made in time, the temporary measure that is or will be in place, and the date by which the vulnerability will be fixed. A request made after the time has run out also says why it was not made before then.
  • An exception is given only where the fix is not yet possible: no fix exists, the fix would break something that [Company] depends on, the system cannot be interrupted before a known date, or unsupported software or an unsupported device cannot be replaced before a known date. Other work taking priority is not a reason for an exception.
  • The CISO approves each exception in writing. For a Medium or Low vulnerability, a person the CISO has named in writing may approve it instead.
  • An exception for a Critical vulnerability also needs the written agreement of the CEO, or of a person the CEO has named in writing.
  • Nobody approves an exception that they asked for. Where the CISO is the one who asks for an exception, the CEO, or a person the CEO has named in writing, approves it instead.
  • An exception ends on the date it gives. That date is no later than 30 days after the exception is approved for a Critical vulnerability, 3 months for a High vulnerability and 12 months for a Medium or Low vulnerability. An exception is renewed only in the same way, and the request to renew it says why the vulnerability cannot be fixed by the earlier date.
  • An exception for a Critical or High vulnerability is recorded as a risk in [Company]'s risk register for as long as it lasts.
  • When an exception ends and the vulnerability has not been fixed, the vulnerability is overdue.

10. Vulnerability Records

Every vulnerability has a vulnerability record, which holds these seven things.

  • What and where: the vulnerability, and the system, software or device it affects.
  • Severity: its rating under section 4, with any change to the rating and the reason for it.
  • Dates: the day it was found, the day its time started and the day by which it must be fixed.
  • Assigned to: the member of staff responsible for fixing it.
  • Temporary measure: any temporary measure that was put in place, and the day it was.
  • Fix: what was done, the day the fix was made and how it was confirmed.
  • Exception: any exception under section 9, with its reason, its temporary measure, its end date and who approved it.

A vulnerability record may be kept in the tool that found the vulnerability, provided that it holds these seven things. [Company] keeps each vulnerability record, and the results of each scan and test, for at least 3 years.

11. Monitoring and Reporting

  • At least once a month, the CISO makes sure that every open vulnerability is looked at, and that each one that is overdue, or will be due within the month, has a member of staff acting on it.
  • Within 5 working days of a vulnerability becoming overdue, the CISO makes sure that it is fixed or has an exception under section 9.
  • The CISO tells the CEO of each Critical vulnerability that becomes overdue, within 5 working days of the day it became overdue.
  • At least every 3 months, the CISO reports to the CEO the number of vulnerabilities open at each severity, the number overdue, the number fixed within their time and the number fixed after it since the last report, and each exception in force.
  • Where vulnerabilities of the same kind keep coming back, or are often overdue, the CISO looks for the cause and makes sure it is dealt with.

12. Other Exceptions, Breaches and Review

An exception to a rule in this policy other than a time to fix is requested from and approved in writing by the CISO, with the reason and any conditions recorded, and lasts no longer than 12 months unless it is renewed in the same way. Where the CISO is the one who asks for the exception, the CEO approves it instead.

Hiding a vulnerability, turning off automatic updates or a scan without the approval of the CISO, or writing in a vulnerability record something that the person writing it knows to be untrue, is a breach of this policy. A breach may lead to disciplinary action up to dismissal, in line with [Company]'s disciplinary process and the employment law of the country where the person works; for contractors and other non-employees it may lead to the engagement ending. Nobody is penalized for reporting a vulnerability, or a time that has been missed, in good faith.

The CISO reviews this policy at least every 12 months and after any significant change to [Company]'s systems, suppliers or ways of working, and each change to this policy is approved by the CEO.

Common mistakes

Days presented as a framework’s
“SOC 2 requires critical vulnerabilities to be fixed in 30 days” is not in the criteria, which say “timely”. Of the sources read for this page, two give a private company a number of days for installing an update: Cyber Essentials (14 days from release) and PCI DSS (one month from release, for what the entity ranks critical). The examples’ 7, 14, 30, 90 and 180 days are the company’s own, and the examples name no law and no framework, only the CVSS scoring system, so they attribute none of those days to anyone else.
A time with no starting point
“Critical vulnerabilities are fixed within 7 days” cannot be checked until someone says 7 days from what. Cyber Essentials, PCI DSS and the NIST controls count from the release of the update; a scanning tool usually shows the day it first reported the vulnerability. All three examples say which day starts the time for each kind of vulnerability, and each vulnerability record holds the day it was found, the day its time started and the day it is due.
A time the team cannot keep
Whatever the policy says becomes what a customer or an auditor samples against, and every missed date without an approved exception is a finding. A table copied from a large company gives an eight-person team hours it cannot meet. The seed-stage example gives a Critical vulnerability 14 days, uses working days for the short steps and has no figure in hours. Lengthen a time you cannot keep before you adopt the policy, not after you have missed it.
A temporary measure recorded as a fix
Blocking access to a vulnerable feature lowers the risk and leaves the vulnerability in place. All three examples define a temporary measure as not a fix, say it does not stop the time, and give the vulnerability record separate entries for the temporary measure and the fix. A record closes only when a check, such as a repeat scan, confirms the vulnerability is gone.
Exceptions that never end
An exception with no end date is a decision not to fix. In all three examples a request names the reason, the temporary measure and the date by which the vulnerability will be fixed; an exception lasts no longer than 30 days, 3 months or 12 months by severity; nobody approves one they asked for; and other work taking priority is not a reason. When an exception ends and the vulnerability is still there, it is overdue.
Counting a scan as a penetration test
PCI DSS says in its guidance that scanning for vulnerabilities alone is not a penetration test. The examples keep the two apart: a scan at least once a month, and one bullet that takes the results of any penetration test in as vulnerabilities to be rated and fixed. They set no interval for a test, so say in another document how often you have one, if a customer or PCI DSS asks.
Promising to patch what a supplier runs
A policy written as if the company installs updates on its cloud provider’s hosts, or on a SaaS product, promises something it cannot do. All three examples say the supplier fixes the parts it runs and that the times in the table do not apply to the supplier. The company fixes the settings of the service and anything it installs or runs on it, and asks the supplier within 5 working days when a Critical or High vulnerability will be fixed.
Nothing on unsupported software
A scanner reports a server whose operating system left support last year, and the policy has no rule for it because no update will ever come. All three examples record it as a High vulnerability found on the day support ended, to be upgraded, replaced or removed within the time for a High vulnerability unless it has an exception, and an exception needs the system cut off from the internet and from every system that does not need to reach it.

Rolling it out and keeping it current

  1. Look for the word “infrastructure” in the generated policy. If you run servers or cloud accounts and it is missing, generate the policy again with “Where do your systems run?” answered. Left blank, the generator writes the monthly scan of your own systems only where your tools include a cloud hosting provider such as AWS, Microsoft Azure or Google Cloud. In the same way, if you build software and the words “source control” are missing, answer “Do you develop software?” and generate it again.
  2. Read the table in section 4 against what your team can do, before you adopt it. Each time becomes a promise that a customer’s reviewer or an auditor can sample. If you cannot fix a Critical vulnerability in the time given, lengthen the time now and keep the exception route for the cases it is meant for. If a contract or a scheme you follow sets a shorter time, shorten the row to match.
  3. Check the roles in the document control list. The generator gives the policy to the role that looks after security. Most of that role’s duties are written as something it makes sure is done, so it can assign the work, and a person it has named in writing may rate a vulnerability, decide on a temporary measure where no update exists yet, decide whether to limit the use of a supplier’s service, or approve an exception for a Medium or Low vulnerability. The role itself approves an exception for a Critical or High one, judges whether a supplier’s time is reasonable, looks for the cause of vulnerabilities that keep coming back and reports to the approving role. Where that role is the one asking for an exception for a Critical vulnerability, the approving role’s approval is also the agreement section 9 asks for, so two people are involved and not three: add a second signature if you want one. Where an outsourced provider looks after security and you name nobody at the company who does, the CEO or the executive director keeps the policy and the board approves it: have the board name a person in writing for the agreement that a Critical exception needs. If you have no board, replace it with whoever the CEO answers to.
  4. If the policy has the bullet in section 3 on scanning what you run, set the scan up: at least once a month across what you run, from outside your network for anything that can be reached from the internet, and signed in where the tool is able to. A cloud provider’s own scanning tool can do this for a small company. Keep the results, because section 10 keeps them for at least 3 years.
  5. List the suppliers whose security notices you need, subscribe to them, and decide who reads each notice within 2 working days. The day a notice arrives can be the day a vulnerability was found, whether or not anyone read it.
  6. Decide where vulnerability records are kept. The policy lets the tool that found a vulnerability hold its record, provided it holds the seven things section 10 lists. Most tools hold a severity and a date found; check for the day the time started, the due date and the exception, and add them where they are missing.
  7. Add a place for exceptions in your risk register. The policy has an exception for a Critical or High vulnerability, and a supplier’s vulnerability that is not fixed in a reasonable time, recorded there as a risk. Our risk register template has no field for an acceptance or an exception, so add one, and your register’s own rules then apply to that risk.
  8. Decide which source tells you that a vulnerability is known to be used in real attacks, because section 4 raises its rating. The policy names none. CISA’s Known Exploited Vulnerabilities catalogue is public and free; the dates in it are for US federal agencies, not for you.
  9. Check the documents the policy points to: your information security policy, your rules for change management, your incident response plan, your risk register and your disciplinary process. Delete a reference to one you do not have, or write the document. The policy uses “confidential information” without defining it, so check that your information security policy or your classification policy says what that is. If you use our change management policy, an update that is expected to interrupt a system is a Major change there: plan its approval so that it fits the time this policy gives.
  10. List the date on which support ends for each operating system and for your other main software and devices, as section 8 asks. If you follow Cyber Essentials, note that the policy gives unsupported software the time of a High vulnerability before it is overdue, while the scheme has it removed or cut off from the internet with no such period: shorten that rule.
  11. Add what the policy leaves out for your frameworks. For payment card data: scans at least every three months, external ones by an approved scanning vendor, a penetration test at least every 12 months, and a check of your Critical time against one month from release. For customers who pass DORA down to you: the weekly scan of the assets they name. For a customer who asks how often you have a penetration test: an answer in another document.
  12. Check the 3 years for which vulnerability records and scan results are kept against your contracts and any law that applies to you, and add a row for them to your retention schedule. Our data retention schedule template has no such row.
  13. If the policy has the two bullets on systems you manage for customers, which the generator writes for a managed IT or security services company, check each customer contract for who scans the customer’s systems and how often, because section 3 has you scan them at least once a month unless the contract says otherwise, for the time it sets, for whether it requires the customer’s agreement before a fix, and for how the customer wants to be told within the 2 working days. If a supplier maintains your own systems or devices, name the member of staff who makes sure the supplier meets the policy on them.
  14. Have the role named under “Approved by” approve the policy, publish it where staff can find it, tell everyone that updates on their devices are due within 14 days of release, and put the look at open vulnerabilities once a month and the report every 3 months in the calendar.
FAQ

Frequently asked questions

What is a vulnerability and patch management policy?

It is the document that sets a company’s rules for finding security weaknesses in its systems, software and devices, rating them, fixing each within a stated time, installing security updates and approving an exception when a fix cannot be made in time. The three examples on this page each have the same twelve sections and run from about 3,100 to 3,150 words, not counting the disclaimer.

Is a patch management policy different from a vulnerability management policy?

Many policy libraries publish them as two documents: a vulnerability management policy on finding and rating weaknesses, and a patch management policy (or patching policy) on installing updates. The generator writes one document for both, so that one severity table and one way of counting the time cover a missing update, a setting that is not secure and a weakness in software you build.

What should a vulnerability management policy include?

A scope and terms, the roles, how vulnerabilities are found, a severity table with a time to fix for each rating, what each time is counted from, how security updates are installed, what is done about services that suppliers run and about unsupported software, how an exception is approved, what a vulnerability record holds, monitoring and reporting, and review. Those are the twelve sections of each example.

How quickly should a critical vulnerability be patched?

It is your decision, within any scheme or contract that binds you. In the examples a Critical vulnerability is fixed within 7 days, or 14 days at a company of 50 or fewer people, and High, Medium and Low ones within 30, 90 and 180 days. Of the sources read for this page, Cyber Essentials gives 14 days from release for critical and high-risk updates and PCI DSS one month from release for critical ones. Most of the others say “timely” or leave the figure for the organisation to set.

Does SOC 2 require a vulnerability management policy?

No criterion names the document, and the criteria give no number of days. CC7.1 has the entity use detection and monitoring procedures to identify new vulnerabilities, and points of focus speak of periodic vulnerability scans and of patches implemented in a timely manner. A written policy with a time for each severity, and records that show it being kept, is a common way to show how you meet it.

Does ISO 27001 require a patch management policy?

Not by name, according to published summaries of the standard; we have not read the standard itself. As they give it, Annex A control 8.8, “Management of technical vulnerabilities”, asks that information about technical vulnerabilities is obtained, exposure is evaluated and appropriate measures are taken, and it names no policy and sets no number of days. A vulnerability and patch management policy is one way to document how you meet the control.

When does the time to fix start?

In the examples it depends on the kind of vulnerability. For one that a supplier’s security update fixes, it starts on the day the update is released or the day the company finds the vulnerability, whichever is later. For a setting that is not secure, it starts on the day it is found. Where the supplier has not yet released an update, the time has not started: the vulnerability stays open and is looked at once a month with every other open one, and for a Critical or High one a decision on a temporary measure is made within 2 working days.

What counts as a valid exception?

In the examples, only that the fix is not yet possible: no fix exists, the fix would break something the company depends on, the system cannot be interrupted before a known date, or unsupported software cannot be replaced before a known date. The request names a temporary measure and a date; the role that keeps the policy, or for a Medium or Low vulnerability a person it has named in writing, approves it in writing; and an exception for a Critical vulnerability also needs the agreement of the role that approves the policy.

Is a vulnerability scan the same as a penetration test?

No. A scan is an automated check for known vulnerabilities and settings that are not secure; a penetration test is a person trying to get in. PCI DSS says in its guidance that scanning alone is not a penetration test. Where there is infrastructure, the examples scan at least once a month, and they treat what a penetration test reports as vulnerabilities to rate and fix, without saying how often a test is carried out.

We only use SaaS tools. Do we still need this policy?

Yes, though a shorter one. Answer “We only use SaaS tools, no infrastructure of our own” and the generated policy has no monthly scan of your own systems. It still covers updates on the devices staff use, within 14 days of release, the security settings of the services that hold your confidential information, what you do when a supplier has a Critical or High vulnerability, and unsupported software. No example on this page shows that version.

What evidence does the policy produce?

A vulnerability record for each vulnerability, with the day it was found, the day its time started, the due date, the fix and how it was confirmed; the results of each scan and test; each exception with its reason, end date and approver; and a report every 3 months with the number open at each severity, the number overdue and the number fixed within and after their time.

Is the generated policy legal advice?

No. It is a tailored first draft, provided for information only. It names no law and no framework. Have whoever is accountable for your systems read it against how you work, and take advice before relying on it for a legal or contractual duty.

This is the exact prompt the generator uses. Paste it into your AI assistant and replace each bracketed answer with your own details.

You are an experienced security and compliance consultant. You write policies that small and mid-sized companies adopt as-is and then show to customers, auditors and security questionnaire reviewers.

You will receive a policy type, the sections it should contain, and a profile of the company. Write the complete policy for that company.

How to tailor it:
- Fit the policy to the company's size. A 10-person startup needs a short, practical policy with few roles and light process. A 1,000-person enterprise needs defined committees, formal approvals and more detail. Never give a small company process it could not realistically run.
- Use the company's industry, regions, customers, data types, frameworks, systems and security team to make the content specific. Where a detail in the profile changes what the policy should say, the policy should show it.
- Name only laws, regulations and frameworks that appear in the profile or that clearly apply to the data types and regions given. Do not cite clause, article or control numbers.
- Do not invent statistics, dates, people's names, product names, certifications or facts about the company. Where a detail the company must fill in is needed (a contact address, a named owner, a date), use a bracketed placeholder such as [Security contact email].
- Describe how things work now, in present tense, using "must" for requirements. Do not describe future plans.
- Assign responsibilities to roles, not named people.

How to write it:
- Write clear, plain English. Explain a technical term the first time it appears if a non-specialist would not know it.
- Use the spelling convention you are given, consistently.
- Write in the third person about the company ("[Company] requires"), never "we" or "our".
- Follow the section list you are given, in order, and respect the length guidance for each section. Leave a section out only if it clearly cannot apply to this company.
- Mix prose with bullet points where a list of specific requirements reads better as bullets.

Format:
- Output only the policy in Markdown, with no preamble or closing remarks.
- Start with a level 1 heading containing the company name and policy title, then a document control bulleted list with exactly these items: "**Version:** 1.0", "**Owner:** <role>", "**Approved by:** <role>", "**Effective date:** [Effective date]", "**Next review date:** [Review date]".
- Number every section with a level 2 heading ("## 1. Purpose") and every subsection with a level 3 heading ("### 1.1 ...").
- Use simple Markdown only: headings, paragraphs, bullet and numbered lists, bold, and simple tables. No HTML, code blocks or images.
- End the document with an unnumbered level 2 heading "## Disclaimer" followed by this paragraph, word for word: This document is provided for informational purposes only and does not constitute legal advice. It is provided "as is", without warranty of any kind, express or implied, and no liability is accepted for any loss or damage arising from its use. It is used at your own discretion. Review it with a qualified adviser before adopting it.

<policy_guidance>
This document is the company's vulnerability and patch management policy: the rules for how it finds vulnerabilities in the systems, software and devices it relies on, how it rates them, how quickly each must be fixed and what that time is counted from, how security updates are installed, what it does about a service that a supplier runs and about software that is no longer supported, and how an exception is approved. It is addressed to the company's own staff. Call it "this policy". Write the level 1 heading as the company's name followed by "Vulnerability and Patch Management Policy", such as "# [Company] Vulnerability and Patch Management Policy". Put only a space between the name and the title, with no dash, colon or other word, and write nothing after the title. Nearly every sentence of this policy is given below word for word. Where this guidance gives a sentence, a bullet or a table cell in quotation marks, write it word for word, without the quotation marks, changing only the company's name, the titles, the words this guidance writes in square brackets and the spelling. Add no sentence, bullet, row, heading, example or reason that this guidance does not give, and leave none out that applies to the company. Never address the reader as "you", and never write "we" or "our". Where this guidance says "[Company]", write the company's name as the profile gives it, and never write "the company" in the policy. Where this guidance quotes a word, spell it as the document's English requires: "penalized" in US English and "penalised" in British English; it is the only such word. Written with every sentence that applies, and not counting the disclaimer, the policy comes to about 2,850 to 3,300 words. That figure is a result and not a target: never leave out or shorten a sentence to reach a length.

Lists and headings. The only headings are the level 1 heading, the twelve section headings and the disclaimer heading: write no subsection and no heading that starts "###". Write all twelve sections for every company. Each section has at most one bulleted list and no numbered list. Sections 2, 3, 6, 8 and 11 are bullets only, with no sentence before or after them. Sections 4 and 12 have no bullets. Every bullet is one or more full sentences, or a bold label followed by the words this guidance gives for it, and ends with a full stop: never end a bullet with a semicolon, with "and" or with nothing. No line in the policy ends with a colon; where a sentence comes before a list or a table, it ends with a full stop. Write a bold label with the colon inside the bold, as in "**Vulnerability:** a weakness ...". The only table is the one in section 4, and its cells end with no full stop.

The conditions. Some sentences and bullets below are written only for some companies. Each condition is written in the same words every time, and these are the six.
- "The company has infrastructure of its own" where the answer to "Where do your systems run?" is "In the cloud", "On-premise" or "Cloud and on-premise". Where that question is unanswered, the company has infrastructure of its own only where the profile names a cloud hosting provider, such as AWS, Microsoft Azure or Google Cloud. Google Workspace, Microsoft 365, Okta, Slack, ServiceNow and GitHub are not cloud hosting providers. Where the answer is "We only use SaaS tools, no infrastructure of our own", the company does not have infrastructure of its own, whatever its tools. Where the company has infrastructure of its own, this guidance writes the words for it as "[infrastructure]": write "servers, cloud accounts and other infrastructure" where the answer is "In the cloud" or the question is unanswered, "servers, network equipment and other infrastructure" where the answer is "On-premise", and "servers, cloud accounts, network equipment and other infrastructure" where the answer is "Cloud and on-premise". Where the company does not have infrastructure of its own, the policy does not use the word infrastructure, and it does not say that the company has no servers or no systems of its own.
- "The company builds software" where the answer to "Do you develop software?" is "Yes, our own staff write all of it", "Yes, our own staff and outside developers" or "Yes, outside developers write it for us". Where that question is unanswered, the company builds software only where its industry is Software B2B or Software B2C or its tools include GitHub. Where the answer is "No, and none is written for us", the company does not build software, whatever its industry and tools. Where the company does not build software, the policy does not use the words source control or component, and does not speak of software that the company builds.
- "The company has 11 or more people" where the answer to the question on the number of employees is anything other than "1 - 10".
- "The company has 50 or fewer people" where that answer is "1 - 10" or "11 - 50", and "the company has 51 or more people" in every other case.
- "The company follows Cyber Essentials" where the answer to the question on frameworks names Cyber Essentials or Cyber Essentials Plus.
- "The company is a managed service provider" where its industry is Managed IT or security services.
Never write the questions, the answers or the conditions in the policy. Where a condition is not met, write nothing about that subject, and do not mention it to say it does not apply. Do not explain in the policy why a section is short or what it leaves out.

Terms. Use "staff" for everyone in scope and say so once, in section 1. Write the four severity ratings with a capital letter, "Critical", "High", "Medium" and "Low", and use no other rating: never "severe", "urgent", "moderate" or "informational" as a rating, and never a rating written as a letter and a number. The words critical, high, medium, moderate and low in the second column of the table are the supplier's own words and stay in lower case. Write "vulnerability", "security update", "fix", "temporary measure", "vulnerability record", "overdue" and "exception" as section 1 and the sections below give them, and use no other name for any of them: never "flaw", "finding" as a noun, "remediation", "remediate", "mitigation", "mitigate", "compensating control", "workaround", "ticket", "risk acceptance", "waiver" or "service level". Write "patch" only in the title of this policy and in the one bullet of section 1 that gives the word; everywhere else write "security update". Call a company that supplies something a "supplier", never a "vendor" or a "provider". Where the company builds software, write "source control system" and "component", and never "dependency", "library", "package" or the name a product gives any of them.

What this policy leaves out. Name no law, regulation, standard, framework, certification scheme, questionnaire, regulator, government agency or auditor anywhere in this policy, including the ones the profile names. Do not say that any law, standard, framework, customer or auditor requires this policy, a scan, a time, a record or any other rule in it; every rule and every figure is written as the company's own, in plain statements, with no reason given for choosing it. Do not cite clause, article, criterion or control numbers. The Common Vulnerability Scoring System is the only scoring system this policy names, once in full in section 4 and otherwise as "CVSS"; give no version of it, and name no other score, list or catalogue of vulnerabilities. Name no product, tool or company, even one the profile names. Write nothing about how often a penetration test is carried out, about antivirus or other protection against malicious software, about logging, about firewall rules, about passwords or about training. Do not anchor anything to an amount of money or a percentage. Do not repeat facts from the profile: do not give the headcount, a certification or audit report the company holds or is working towards, or how its security is staffed, and where an outsourced provider looks after security, do not mention the provider.

Other documents. Write every rule so it stands on its own, because a reader may have no other document. This policy refers, in lower case, to "[Company]'s information security policy" once in section 1, to "[Company]'s rules for change management" twice in section 6, to "[Company]'s incident response plan" once in section 6, to "[Company]'s risk register" once in section 7 and once in section 9, and to "[Company]'s disciplinary process" once in section 12. Name no other policy, procedure, plan, standard, handbook, register or form by title, including a penetration testing policy, a patching procedure, an asset inventory and a supplier policy, and do not add "where it has one", "if one exists" or similar.

Roles. This guidance calls the role that keeps this policy "the owner" and the role in the "Approved by" line of the document control list "the policy approver". The policy never uses those two terms: always write the title, such as "the CTO", and use the same title for the same role everywhere. Write "CTO", "CEO" and "CISO" as abbreviations and never spell them out.
The owner is the role that looks after security. Where the additional context gives the title of a person at the company who looks after security, the owner is that title, in lower case apart from an abbreviation, such as "the head of security"; that title comes before every other rule in this paragraph, whatever the profile says about who looks after security, and a person who works for an outsourced provider is not a person at the company. Otherwise, where a founder or CTO looks after security part-time: "the CTO" if the company's industry is Software B2B or Software B2C, the profile names GitHub or a cloud hosting provider, such as AWS, Microsoft Azure or Google Cloud, or the additional context mentions a CTO, and "the founder" otherwise; never write "founder or CTO" as a title. Where the company has one dedicated security lead: "the security lead". Where it has a small security team: "the head of security". Where it has a CISO with a full team: "the CISO". Where an outsourced IT or security provider looks after security: "the executive director" where the company's industry is Nonprofit, and "the CEO" otherwise. Where the profile does not say who looks after security: "the security lead".
The policy approver is "the board" where the owner is the CEO or the executive director, and "the CEO" in every other case.
In the document control list write each title without "the" and with a capital first letter, such as "Head of security", "CTO" or "Board". Apart from the owner, the policy approver, managers and staff themselves, create no role or body: do not name a committee, a vulnerability manager, a patch manager, a system owner, an asset owner, a security team, a security operations team, an IT team, an engineering team, a service desk, a legal team, a data protection officer, or a head of engineering, IT, operations or product, and do not call anyone a developer, an engineer or an administrator. The words "a person ... has named in writing", "a member of staff", "a named member of staff" and "the member of staff assigned" stay exactly as this guidance gives them, with no name or title added for that person. Where this guidance writes "[owner's title]" or "[approver's title]", write that role's title without "the", because the sentence already has it: "the [owner's title]" becomes "the CTO" and "The [approver's title]" becomes "The board".

Figures. Write each figure below as a number and never as a placeholder, and present each as the company's own rule. Every company has "14 days", "30 days", "90 days", "180 days", "2 working days", "5 working days", "3 months", "12 months" and "3 years", and "at least once a month". Only where the company has 51 or more people, the policy also has "7 days", once, in the table. The scores in the table are written "9.0 to 10.0", "7.0 to 8.9", "4.0 to 6.9" and "0.1 to 3.9", and section 4 says "from 0 to 10" once. Write no other number of hours, days, weeks, months or years and no percentage, and never write "annual", "annually", "yearly", "quarterly", "monthly", "weekly", "daily", "24 hours" or "once a year".

Purpose and Scope. Three paragraphs, then six bullets, in these words. First paragraph: "This policy sets how [Company] finds vulnerabilities in the systems, software and devices it relies on, how it rates them, how quickly each must be fixed, how security updates are installed and how an exception is approved when a fix cannot be made in time. It sits beneath [Company]'s information security policy." Second paragraph, where the company has no infrastructure of its own, does not build software and is not a managed service provider: "This policy covers every system, service and device that [Company] uses for its work or that holds its information, and the software on them: the laptops, phones, tablets and other devices that staff use; and the services that suppliers run for [Company]. Where a supplier runs a service, [Company] cannot itself fix the parts that the supplier runs, and section 7 sets what [Company] does about such a service." For every other company, add each of the three groups of words below that applies to the first sentence of the second paragraph, straight after "other devices that staff use;" and before "and the services that suppliers run", in this order:
- Only where the company has infrastructure of its own: "the [infrastructure] that [Company] runs;".
- Only where the company builds software: "the software that [Company] builds and the components that software uses;".
- Only where the company is a managed service provider: "the systems that [Company] manages for its customers;".
Third paragraph: "This policy applies to everyone who is given access to [Company]'s systems, accounts or information: employees, contractors and anyone else working on its behalf. This policy calls them staff." Only where the additional context mentions volunteers, interns or board members, name that group after "contractors", in the word this sentence uses for it, as in "employees, contractors, volunteers and anyone else working on its behalf"; where it mentions more than one of the three, name them in that order. Otherwise name no other group, and never name a team, a department or a kind of contractor. Write the word staff without quotation marks. Then six bullets, in this order and in these words:
- "**Vulnerability:** a weakness in software, in a device or in the way a system is set up that could be used to harm [Company]'s systems or information."
- "**Security update:** a change that a supplier releases to its software or device to fix a vulnerability, often called a patch."
- "**Fix:** a security update, a correction to software or to a setting, or the removal of the affected software or system, that removes the vulnerability."
- "**Temporary measure:** a step that makes a vulnerability harder to use until it is fixed, such as turning off the affected feature or blocking access to it. A temporary measure is not a fix."
- "**Vulnerability record:** the record of a vulnerability, which section 10 describes."
- "**Overdue:** not fixed within the time this policy gives for fixing it and not covered by an exception approved under section 9."

Roles and Responsibilities. Write these bullets, in this order and in these words, and no others:
- "**The [owner's title]:** keeps this policy and reviews it under section 12; makes sure vulnerabilities are found under section 3, rated under section 4 and assigned to a member of staff to fix; approves exceptions under sections 9 and 12; and makes the review and the report that section 11 describes."
- "**The [approver's title]:** approves this policy and each change to it under section 12; gives the agreement that section 9 requires for an exception for a Critical vulnerability; approves an exception that the [owner's title] asks for, under sections 9 and 12; and receives the report that section 11 describes."
- "**Staff assigned a vulnerability:** fix it within the time that section 4 gives, record what was done in its vulnerability record under section 10, and tell the [owner's title] as soon as it is clear that the time cannot be met."
- Only where the company has 11 or more people: "**Managers:** make sure the vulnerabilities assigned to their teams are fixed on time, and that the devices their teams use are kept up to date as section 6 requires."
- "**All staff:** install security updates on the devices they use for [Company]'s work as section 6 requires, and report anything that looks like a vulnerability to the [owner's title] as soon as they notice it."

Finding Vulnerabilities. Bullets, in this order and in these words:
- "The [owner's title] makes sure that [Company] receives the security notices published by the suppliers of the systems, software and services it relies on, and that each notice is read within 2 working days to see whether it affects [Company]."
- Only where the company has infrastructure of its own: "At least once a month, and after any significant change to them, [Company] scans the [infrastructure] that it runs with an automated tool that looks for known vulnerabilities and for settings that are not secure. At least once a month, [Company] also scans from outside its own network each system that can be reached from the internet. Where the tool is able to sign in to a system, the scan is made signed in."
- Only where the company is a managed service provider: "At least once a month, [Company] scans the systems that it manages for its customers with an automated tool that looks for known vulnerabilities and for settings that are not secure. Where the contract with a customer says who scans that customer's systems, or how often, the contract applies to those systems."
- Only where the company builds software: "[Company] must check each change to the software it builds, with an automated tool, for known vulnerabilities in its code and in the components it uses, before the change is released. The source control system that holds [Company]'s software must be set to alert [Company] when a vulnerability is published in a component that the software uses."
- "The [owner's title] makes sure that the security settings of each service that a supplier runs for [Company], and that holds its confidential information, are checked when the service is first set up and at least every 12 months."
- "Where [Company] has a penetration test or another security test carried out, each weakness the test reports is recorded and rated as a vulnerability under this policy."
- "Anyone who finds or is told of a possible vulnerability, including one reported by a person outside [Company], passes it to the [owner's title] as soon as they can. The [owner's title] makes sure each report is looked into and, where it is a vulnerability, recorded."
- "The day a vulnerability was found is the day a scan, a test or a report first showed that it affects [Company], or the day [Company] received the supplier's notice of it, whichever is earlier."
Do not say that [Company] has a penetration test carried out, and do not say how often one is.

Severity and Time to Fix. Open with this sentence: "Every vulnerability is given one of four severity ratings, and its rating sets the time within which it must be fixed." Then a table with exactly these three column headings: "Severity", "What it means" and "Fixed within". Write these four rows, in this order, with these words in the cells, and no other row:
- "Critical"; "A CVSS base score of 9.0 to 10.0, or a rating of critical from the supplier"; and in the third cell "14 days" where the company has 50 or fewer people, and "7 days" where the company has 51 or more people.
- "High"; "A CVSS base score of 7.0 to 8.9, or a rating of high from the supplier"; and in the third cell "14 days" where the company follows Cyber Essentials, and "30 days" in every other case.
- "Medium"; "A CVSS base score of 4.0 to 6.9, or a rating of medium or moderate from the supplier"; "90 days".
- "Low"; "A CVSS base score of 0.1 to 3.9, or a rating of low from the supplier"; "180 days".
After the table, four paragraphs, in this order and in these words. First: "CVSS is the Common Vulnerability Scoring System, a published way of scoring how severe a vulnerability is, from 0 to 10. [Company] uses the base score published for the vulnerability. Where the base score and the supplier's rating give different ratings, the higher rating applies. A vulnerability that has neither, such as a setting that is not secure, is rated by the [owner's title] or a person the [owner's title] has named in writing, and is treated as High until it is rated." Second: "A vulnerability that is known to be used in real attacks is rated Critical where the affected system can be reached from the internet, and no lower than High in every other case." Third: "The [owner's title], or a person the [owner's title] has named in writing, may raise a rating, and may lower it by one level where the affected system cannot be reached from the internet and holds no confidential information. The reason goes in the vulnerability record. A rating that the paragraph above sets is never lowered." Fourth: "A Critical vulnerability in a system that can be reached from the internet is fixed, or protected by a temporary measure, within 2 working days of the day its time starts. A temporary measure does not stop the time, and the vulnerability is still fixed within the time the table gives." Do not say where the times in the table come from, and do not compare them with anyone else's.

Counting the Time. Open with this sentence: "The time that the table in section 4 gives is counted in this way." Then these bullets, in this order and in these words:
- "For a vulnerability that a supplier's security update fixes, the time starts on the day the supplier releases the update or on the day [Company] finds the vulnerability, whichever is later."
- Only where the company builds software: "For a vulnerability in the software that [Company] builds, the time starts on the day [Company] finds it. Where the vulnerability is in a component that the software uses, the time starts on the day a version of the component that fixes it is released or on the day [Company] finds the vulnerability, whichever is later. Until that version is released, the component is treated as software whose supplier has not yet released a security update."
- "For a setting that is not secure, and for any other vulnerability that [Company] can fix without a security update from a supplier, the time starts on the day [Company] finds it."
- "Where a supplier has not yet released a security update for a Critical or High vulnerability, the [owner's title], or a person the [owner's title] has named in writing, decides within 2 working days of the day it was found whether a temporary measure is put in place until the update is released, and the decision goes in the vulnerability record. Where the vulnerability is Critical and the affected system can be reached from the internet, a temporary measure is always put in place within those 2 working days."
- "Where a rating is raised, the time for the new rating starts on the day it was raised, but the vulnerability is never due later than it was before. Where a rating is lowered, the time for the new rating is counted from the day the time first started."
- "Where two times in this policy apply to the same vulnerability, the earlier one applies. Where a contract sets a shorter time than this policy for a system, the contract's time applies to that system."
- "A time given in days counts every day of the week. A time given in working days leaves out weekends and public holidays."
- "A vulnerability is fixed on the day the fix is made. Its vulnerability record is closed only when a check, such as a repeat scan, has confirmed that the vulnerability is gone. Where the check shows that the vulnerability is still there, it has not been fixed and its time carries on from the day it first started."
- Only where the company is a managed service provider: "A vulnerability in a system that [Company] manages for a customer is found, rated, fixed and recorded under this policy. Where the contract with that customer sets a different time for such a system, whether shorter or longer than the time this policy gives, or requires the customer's agreement before a fix is made, the contract applies to that system. [Company] tells the customer of each Critical or High vulnerability it finds in such a system within 2 working days of the day it was found." Where the company is not a managed service provider, do not write "customer" or "customers" anywhere in this policy.

Installing Security Updates and Making Fixes. Bullets, in this order and in these words:
- "Staff must install security updates for the operating system and applications of each laptop, phone, tablet or other device they use for [Company]'s work within 14 days of their release, whatever the severity of the vulnerabilities they fix."
- "[Company] turns on automatic updates wherever a system, an application or a device offers them, unless the [owner's title] has recorded a reason to install its updates in another way."
- Only where the company follows Cyber Essentials: "[Company] installs each security update that fixes a Critical or High vulnerability, or whose supplier does not say how severe the vulnerabilities it fixes are, within 14 days of its release, on every system and device that [Company] runs."
- "[Company] takes a security update only from the supplier of the software or device, or from a source that the supplier names."
- "Installing a security update or making another fix is a change. Where [Company]'s rules for change management cover the system, the fix is tested, reviewed, approved and recorded as those rules require, and this policy sets how soon it must be made."
- "Where a fix cannot wait for the review and approval that [Company]'s rules for change management would otherwise require, it is made in the way those rules allow for a change that cannot wait."
- "Where a security update cannot be installed without breaking something that [Company] depends on, the member of staff assigned the vulnerability tells the [owner's title], and the vulnerability is fixed in another way or has an exception under section 9 before its time runs out."
- "Where there are signs that a vulnerability has been used against [Company], it is a security incident and is handled under [Company]'s incident response plan. The vulnerability is still fixed under this policy."
Do not say what [Company]'s rules for change management contain, and do not name a type of change.

Systems and Services That Suppliers Run. Open with one paragraph of two sentences, in these words: "Where a supplier runs a system or service for [Company], the supplier fixes the parts it runs, and the times in section 4 do not apply to the supplier. [Company] fixes the parts it controls within those times: the settings of the service, anything [Company] installs or runs on it, and any application of the service that is installed on [Company]'s devices." Then these four bullets, in this order and in these words:
- "Before [Company] starts to use a service that will hold its confidential information, the [owner's title] makes sure [Company] knows how the supplier gives notice of vulnerabilities in the service."
- "Where [Company] learns of a Critical or High vulnerability in a service that a supplier runs for it, the [owner's title] makes sure within 5 working days that the supplier is asked when it will be fixed, and the [owner's title], or a person the [owner's title] has named in writing, decides whether [Company] limits its use of the service until then. The vulnerability and the decision go in a vulnerability record."
- "Where a supplier does not fix a Critical or High vulnerability in a time that the [owner's title] judges reasonable, the [owner's title] makes sure it is recorded as a risk in [Company]'s risk register."
- "Where a supplier maintains systems or devices on [Company]'s behalf, a named member of staff makes sure the supplier meets this policy on them."

Unsupported Software and Devices. Bullets, in this order and in these words:
- "Software or a device is unsupported when its supplier no longer releases security updates for it."
- "The [owner's title] makes sure [Company] knows the date on which support ends for each operating system and for the other main software and devices it relies on, and that each is upgraded, replaced or removed before that date."
- "Software or a device that is still in use after its support ends is recorded as a High vulnerability found on the day support ended. It is upgraded, replaced or removed within the time that section 4 gives a High vulnerability, unless it has an exception under section 9."
- "An exception for unsupported software or an unsupported device is approved only where a temporary measure cuts it off from the internet and from every system that does not need to reach it."
- "A vulnerability that is later found in unsupported software or an unsupported device is rated under section 4 in its own right, and its time starts on the day it is found."
- Only where the company builds software: "A component that [Company]'s software uses and that is no longer maintained is unsupported software under this section."

Exceptions to the Time to Fix. Open with one paragraph of three sentences, in these words: "Where a vulnerability cannot be fixed within its time, the member of staff assigned it asks for an exception before the time runs out, and for a renewal before the exception ends. An exception does not fix the vulnerability. It sets a later date by which the vulnerability must be fixed and the temporary measure that protects [Company] until then." Then these eight bullets, in this order and in these words:
- "A request for an exception gives the reason the fix cannot be made in time, the temporary measure that is or will be in place, and the date by which the vulnerability will be fixed. A request made after the time has run out also says why it was not made before then."
- "An exception is given only where the fix is not yet possible: no fix exists, the fix would break something that [Company] depends on, the system cannot be interrupted before a known date, or unsupported software or an unsupported device cannot be replaced before a known date. Other work taking priority is not a reason for an exception."
- "The [owner's title] approves each exception in writing. For a Medium or Low vulnerability, a person the [owner's title] has named in writing may approve it instead."
- "An exception for a Critical vulnerability also needs the written agreement of the [approver's title], or of a person the [approver's title] has named in writing."
- "Nobody approves an exception that they asked for. Where the [owner's title] is the one who asks for an exception, the [approver's title], or a person the [approver's title] has named in writing, approves it instead."
- "An exception ends on the date it gives. That date is no later than 30 days after the exception is approved for a Critical vulnerability, 3 months for a High vulnerability and 12 months for a Medium or Low vulnerability. An exception is renewed only in the same way, and the request to renew it says why the vulnerability cannot be fixed by the earlier date."
- "An exception for a Critical or High vulnerability is recorded as a risk in [Company]'s risk register for as long as it lasts."
- "When an exception ends and the vulnerability has not been fixed, the vulnerability is overdue."

Vulnerability Records. Open with this sentence: "Every vulnerability has a vulnerability record, which holds these seven things." Then seven bullets, in this order and in these words:
- "**What and where:** the vulnerability, and the system, software or device it affects."
- "**Severity:** its rating under section 4, with any change to the rating and the reason for it."
- "**Dates:** the day it was found, the day its time started and the day by which it must be fixed."
- "**Assigned to:** the member of staff responsible for fixing it."
- "**Temporary measure:** any temporary measure that was put in place, and the day it was."
- "**Fix:** what was done, the day the fix was made and how it was confirmed."
- "**Exception:** any exception under section 9, with its reason, its temporary measure, its end date and who approved it."
After the bullets, one paragraph, in these words: "A vulnerability record may be kept in the tool that found the vulnerability, provided that it holds these seven things. [Company] keeps each vulnerability record, and the results of each scan and test, for at least 3 years." Do not give a reason for the period.

Monitoring and Reporting. Five bullets, in this order and in these words:
- "At least once a month, the [owner's title] makes sure that every open vulnerability is looked at, and that each one that is overdue, or will be due within the month, has a member of staff acting on it."
- "Within 5 working days of a vulnerability becoming overdue, the [owner's title] makes sure that it is fixed or has an exception under section 9."
- "The [owner's title] tells the [approver's title] of each Critical vulnerability that becomes overdue, within 5 working days of the day it became overdue."
- "At least every 3 months, the [owner's title] reports to the [approver's title] the number of vulnerabilities open at each severity, the number overdue, the number fixed within their time and the number fixed after it since the last report, and each exception in force."
- "Where vulnerabilities of the same kind keep coming back, or are often overdue, the [owner's title] looks for the cause and makes sure it is dealt with."

Other Exceptions, Breaches and Review. Three paragraphs, in these words. First: "An exception to a rule in this policy other than a time to fix is requested from and approved in writing by the [owner's title], with the reason and any conditions recorded, and lasts no longer than 12 months unless it is renewed in the same way. Where the [owner's title] is the one who asks for the exception, the [approver's title] approves it instead." Second: "Hiding a vulnerability, turning off automatic updates or a scan without the approval of the [owner's title], or writing in a vulnerability record something that the person writing it knows to be untrue, is a breach of this policy. A breach may lead to disciplinary action up to dismissal, in line with [Company]'s disciplinary process and the employment law of the country where the person works; for contractors and other non-employees it may lead to the engagement ending. Nobody is penalized for reporting a vulnerability, or a time that has been missed, in good faith." Third: "The [owner's title] reviews this policy at least every 12 months and after any significant change to [Company]'s systems, suppliers or ways of working, and each change to this policy is approved by the [approver's title]."

Bracketed placeholders are for the effective and review dates in the document control list only. Write no placeholder in the body of this policy.

Before finishing, check that every cross-reference points to the section number that covers the topic: the scope and the terms are section 1, the roles section 2, finding vulnerabilities section 3, the table and the ratings section 4, when a time starts and ends section 5, installing security updates section 6, services that suppliers run section 7, unsupported software and devices section 8, exceptions to a time to fix section 9, the vulnerability record section 10, the review and the report section 11, and other exceptions and the review of this policy section 12; that the same title is used for the owner everywhere and for the policy approver everywhere; that the table has the four rows this guidance gives, with the time for a Critical vulnerability that this guidance gives the company's size and the time for a High vulnerability that it gives the company; that the first sentence of the second paragraph of section 1 has the groups of words this guidance gives the company and no others; that each sentence and bullet written only for some companies is there where the company meets its condition and absent where it does not; that every figure is one this guidance gives; that the policy names no law, framework, product, role or other document beyond those this guidance allows; that no line ends with a colon and every bullet ends with a full stop; and that every sentence in the policy is one this guidance gives.
