Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation at post-design stages directly exercises control-flow paths and reveals mismatches between implemented and intended behavior.

SA-15 Development Process, Standards, and Tools partial match

Requiring a documented development process and supporting tools reduces the chance that incorrect control-flow logic is introduced in the first place.

SI-2 Flaw Remediation partial match

Flaw identification and remediation processes can locate and correct control-flow errors once they manifest as incorrect runtime behavior.

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.PS-06 mostly match
prevents

Secure SDLC practices directly prevent incorrect control-flow implementations via reviews, testing, and static analysis.

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

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance can detect paths that deviate from intended logic.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle processes can catch incorrect control-flow logic during design and code review.

A.8.28 Secure coding partial match
prevents

Secure coding standards and reviews directly target flawed control-flow implementations.

A.8.32 Change management partial match
prevents

Change-management gates may prevent deployment of flawed logic but do not address the coding defect itself.
