Plan, establish, implement and maintain an audit programme covering frequency, methods, responsibilities, planning requirements and reporting, taking account of the importance of the processes concerned and the results of previous audits. Define the criteria and scope of each audit, select auditors and conduct audits in a way that ensures objectivity and impartiality of the audit process, report results to relevant management, and retain documented information as evidence of the programme and the results.
ISO 27001:2022 9.2.2 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ISO 27001:2022 your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 79 of 93 ISO 27001:2022 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. 170 were rejected on the NIST SP 800-53 Rev 5 pair alone.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
