Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation directly exercises initialization paths and can reveal missing or incorrect resource setup.

Engineering principles applied during design and implementation can require explicit initialization to a known state.

Requiring the system to fail to a known state structurally reduces the chance that uninitialized resources remain reachable.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly enforce proper resource initialization during coding and testing.

finds

Security testing can detect uninitialized variables but does not itself enforce initialization practices.

prevents

Configuration management can enforce secure defaults and initialization settings but is not the primary control for code-level initialization.

prevents

Secure development life cycle mandates initialization checks and secure defaults that directly prevent improper resource initialization.

prevents

Secure system architecture and engineering principles require explicit initialization of resources and secure state management.

prevents

Secure coding standards explicitly forbid uninitialized variables and mandate proper resource initialization before use.
