Requires an incident handling capability covering preparation, detection and analysis, containment, eradication and recovery, consistent with the incident response plan, coordinated with contingency planning, improved by lessons learned that are fed back into procedures, training and testing, and applied with comparable rigour across the organization.
NIST SP 800-53 Rev 5 IR-4 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.
