Mitigating Controls (NIST 800-53 r5) AI

Requiring cryptographic protection mechanisms forces correct signature verification to be implemented for data protection.

Mandating integrity verification tools directly requires proper cryptographic signature checking to detect unauthorized changes.

Protecting session authenticity requires correct verification of cryptographic signatures or equivalent mechanisms.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 mostly match
prevents

Digital signatures are explicitly cited to protect integrity of data-at-rest, so proper verification directly mitigates the weakness.

PR.DS-02 mostly match
prevents

Digital signatures are explicitly cited to protect integrity of data-in-transit, so proper verification directly mitigates the weakness.

ID.RA-09 partial match
prevents

Requires assessing authenticity and integrity of acquired assets, which commonly relies on signature verification but is limited to pre-acquisition.

PR.PS-06 partial match
prevents

Secure SDLC practices include code signing and signature verification requirements, addressing the weakness during development.
