Does your organization have formal agreements with third parties (e.g., ISPs, MSSPs) authorizing them to perform containment actions during security incidents?

Explanation

Third-party containment authority is under review, namely whether formal agreements let parties like ISPs or MSSPs take containment actions during your security incidents. Such arrangements can be crucial during critical incidents when internal resources may be overwhelmed or when specialized expertise is required for effective containment.

Evidence could include signed service level agreements (SLAs) with third parties that explicitly authorize containment actions, documented procedures for third-party incident response, or records of tabletop exercises conducted with these third parties to test containment procedures.

Implementation Example

Allow a third party (e.g., internet service provider, managed security service provider) to perform containment actions on behalf of the organization
