Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and code analysis can discover missing or incorrect return-value checks.

Documented development standards and tools can mandate verified checking of every function return value.

Security engineering principles include requirements for robust error checking of all function returns.

finds

Security testing in development catches missing or incorrect return-value checks.

prevents

Secure SDLC mandates return-value checks and error handling, directly reducing CWE-253.

prevents

Application security requirements include robust error handling that mitigates incorrect return-value checks.

prevents

Secure architecture principles require defensive coding practices such as validating function results.

prevents

Secure coding explicitly demands checking return values, covering most of CWE-253.
