Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Baseline configuration defines the approved production state that must exclude active debug code.

Least functionality explicitly prohibits enabling unnecessary debug or diagnostic features in production builds.

Documented development standards and tools can require removal of debug code before release.

Security-integrated SDLC processes ensure debug artifacts are stripped prior to deployment.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require removal of debug code before release, covering most of this weakness while the control addresses many other development issues.

finds

Security testing in development and acceptance catches active debug code before deployment.

prevents

Configuration management can disable or remove debug features through hardened baselines.

prevents

Secure development life cycle mandates removal of debug code before release.

prevents

Secure coding standards explicitly prohibit leaving debug code active in production.

prevents

Separation of environments reduces risk of debug code reaching production but does not directly address its removal.

prevents

Change management can enforce removal of debug code as part of release gates.
