Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation directly checks whether implemented functions match their specifications.

Security function verification confirms that functions operate according to their defined expected behavior.

Requiring a documented security architecture and design reduces the chance that implementation deviates from intended 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 full match
prevents

Secure SDLC practices directly enforce specification compliance and catch expected-behavior violations during development.

ID.IM-02 partial match
prevents

Security testing and exercises help discover behavior deviations before deployment.

ID.RA-01 partial match
prevents

Vulnerability identification can surface spec-violating flaws, while eliminating the weakness reduces some vulnerability backlog.

PR.PS-02 partial match
prevents

Routine software maintenance and patching can remediate discovered specification violations.

finds

Security testing in development and acceptance validates that functions behave as specified.

prevents

Secure development life cycle mandates verification against specifications, directly reducing expected-behavior violations.

prevents

Application security requirements explicitly define expected behavior that must be met.

prevents

Secure coding practices enforce adherence to functional specifications during implementation.

finds

Change management can catch specification deviations introduced by modifications.

none

Documented operating procedures reduce the chance that functions deviate from intended behavior.
