Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation partial 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 partial match

prevents

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

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.8.25 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.8.27 Secure system architecture and engineering principles partial match

removes

A.8.28 Secure coding partial match

prevents

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

A.8.29 Security testing in development and acceptance partial match

finds

Security testing can detect incorrect comparison results during development and acceptance.

A.8.8 Management of technical vulnerabilities partial match

removes
