Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires disabling or removing non-essential functions such as active debug code that enables step-through execution and password extraction.

prevent

Mandates developer testing and evaluation to identify and eliminate residual debug code before production release of FortiClient.

respond

Requires timely remediation of the known flaw (CWE-489) via patches that remove the active debug capability from affected FortiClient versions.

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.

detects

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.
