Mitigating Controls (NIST 800-53 r5) AI

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

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

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

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

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