Mitigating Controls (NIST 800-53 r5) AI
Developer testing and code evaluation can discover instances where return values are ignored.
Requiring a documented development process and coding standards can mandate explicit checking of all function return values.

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.
Secure SDLC practices directly require checking and handling all function return values to detect error conditions.

Security testing in development and acceptance can detect missing return-value checks.
Secure development life cycle mandates verification of return values to prevent undetected failures.
Application security requirements include input/output validation and error handling that covers return-value checks.
Secure system architecture and engineering principles require robust error handling and defensive coding practices.
Secure coding explicitly requires checking return values to avoid CWE-252.
