NIST SP 800-172 3.5.2e is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of NIST SP 800-172 your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 24 of 35 NIST SP 800-172 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. 5 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.
