Mitigating Controls (NIST 800-53 r5) AI

SR-4 Provenance good match

Requires documented, valid provenance for components, preventing acceptance of code from outside the trusted sphere.

SR-11 Component Authenticity partial match

Implements detection and prevention of counterfeit or inauthentic components before they are integrated.

SR-3 Supply Chain Controls and Processes partial match

Establishes processes to identify and address supply-chain weaknesses that would allow untrusted functionality.
