Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover missing NULL checks on function returns that may dereference.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented development standards and tools can enforce mandatory error-return checking before dereference.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can mandate defensive coding such as explicit null checks before dereference.
