The ISMS has to include both the documented information this standard requires and whatever further documented information the organization judges it needs for an effective ISMS. The note says the amount can vary with the size and type of organization, the complexity of processes and how they interact, and the competence of people.
ISO 27001:2022 clause-7.5.1 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.
