Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation partial match

Developer testing and static analysis can discover format-string vulnerabilities before deployment.

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

Secure development standards and tools can mandate use of static format strings or safe formatting APIs.

SI-10 Information Input Validation partial match

Input validation can reject or sanitize externally supplied format strings before they reach formatting functions.
