For systems that process personally identifiable information: (a) Apply the following processing rules to data elements of personally identifiable information: [Assignment: organization-defined processing rules]; (b) Monitor for permitted processing at the external interfaces to the system and at key internal boundaries within the system; (c) Document each processing exception; and (d) Review and remove exceptions that are no longer supported.
NIST SP 800-53 Rev 5 NIST800-SC-7(24) 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 1014 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.
