Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis directly find uses of uninitialized variables before deployment.

Documented development standards and tools can enforce initialization requirements in code.

Engineering principles can mandate explicit variable initialization to avoid uninitialized use.
