Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover incorrect comparison logic after implementation but does not stop the flaw from being written.

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

Requiring a documented development process and tools can embed standards that reduce introduction of erroneous comparison factors.

Mitigating Controls (NIST CSF 2.0) AI

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 activities such as code review and logic testing directly prevent incorrect comparison factors in code.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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 can detect incorrect comparison results during development and acceptance.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes requirements and reviews that can catch incorrect comparison logic.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify correct comparison criteria and validation rules.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address proper comparison logic and factor selection.
