RS.AN-06.325
Does your organization require incident responders and other relevant personnel to maintain immutable records of all actions taken during incident response activities?
Explanation
Maintaining immutable records of incident response actions creates an audit trail that cannot be altered after the fact, ensuring accountability and providing crucial forensic evidence. These records should capture all actions taken by incident responders, system administrators, and cybersecurity engineers during an incident, including system changes, communication logs, and investigative steps. Evidence of compliance could include screenshots or documentation of a tamper-proof logging system, examples of incident response logs with timestamps and user attribution, or written procedures that mandate the use of write-once media or blockchain-based logging solutions for incident documentation.
Implementation Example
Require each incident responder and others (e.g., system administrators, cybersecurity engineers) who perform incident response tasks to record their actions and make the record immutable
