(a) Employ only government off-the-shelf or commercial off-the-shelf information assurance and information assurance-enabled information technology products that compose an NSA-approved solution to protect classified information when the networks used to transmit the information are at a lower classification level than the information being transmitted; and (b) Ensure that these products have been evaluated and/or validated by NSA or in accordance with NSA-approved procedures.
NIST SP 800-53 Rev 5 NIST800-SA-4(6) 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.
