Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Security engineering principles include robust exception management to keep the system in a defined state.

Fail-in-known-state reduces the impact when an uncaught exception occurs by preserving a safe condition.

Error handling requirements force structured catching and response to exceptions instead of allowing them to propagate uncaught.

PR.PS-06 mostly match
prevents

Secure SDLC practices explicitly require structured exception handling to prevent uncaught exceptions from reaching production.

finds

Security testing can detect uncaught exceptions before production deployment.

prevents

Secure development lifecycle includes exception-handling standards that reduce uncaught exceptions.

prevents

Application security requirements typically mandate robust error and exception handling.

prevents

Secure architecture principles call for centralized, comprehensive exception management.

prevents

Secure coding standards directly require catching and handling exceptions to prevent crashes or leaks.
