Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover uninitialized pointer accesses through static analysis, dynamic testing, or fuzzing before deployment.

Requiring documented development processes and tools enables use of analyzers or coding standards that identify uninitialized pointer defects.

Security engineering principles can mandate memory-safety practices and language choices that structurally avoid uninitialized pointer use.

Secure SDLC practices directly prevent uninitialized pointer bugs via coding standards, analysis, and reviews, but eliminating this single weakness only partially fulfills the broader control.
