Requires the incident response capability serving the system to be tested for effectiveness at an organization-defined frequency using the test types the organization has defined, so readiness is demonstrated rather than assumed.
NIST SP 800-53 Rev 5 NIST800-IR-3 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of NIST SP 800-53 Rev 5 your existing evidence covers. Hold ISO 27001:2022 and 163 of 300 NIST SP 800-53 Rev 5 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 342 were rejected on the ISO 27001:2022 pair alone.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
