Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover incomplete string comparisons through targeted test cases.

AC-25 Reference Monitor partial match

A reference monitor must be small and correct, structurally limiting the chance of flawed comparison logic in authorization decisions.

AC-3 Access Enforcement partial match

Access enforcement depends on correct authorization checks; partial comparisons would violate the required enforcement of full authorizations.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles include correct and complete comparison logic to avoid flawed decision points.

SI-10 Information Input Validation partial match

Input validation requirements force complete rather than partial string comparisons before decisions are made.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent unsafe string comparisons by enforcing proper API usage and testing.

ID.RA-01 partial match

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

Security testing can detect and prevent partial string comparison flaws before deployment.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle practices can include requirements to avoid partial string comparisons in authentication or validation logic.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate full, exact comparisons for sensitive operations.

A.8.27 Secure system architecture and engineering principles partial match
degrades

Secure system architecture principles discourage unsafe partial comparisons in critical paths.

A.8.28 Secure coding partial match
prevents

Secure coding standards can explicitly prohibit substring-based comparisons for security decisions.

A.8.5 Secure authentication partial match
degrades

Secure authentication mechanisms can reduce reliance on partial string comparisons for credential or token validation.
