Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation partial match

Developer testing and evaluation can reveal cases where security code has been optimized away.

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

Documented developer processes and standards can mandate coding patterns and compiler flags that preserve security-critical operations.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles include requirements for correct implementation of protection mechanisms that survive compilation.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require techniques that preserve security-critical code against compiler optimizations.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect optimization-induced removal of security mechanisms.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC requires compiler and build-process controls that can prevent optimization removal of security code.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly address compiler flags and volatile/optimization barriers for security-critical code.
