Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis locate hard-coded sensitive values before code is deployed.

Enforces access so that source containing embedded secrets cannot be reached by unauthorized parties.

Engineering principles require secrets to be externalized rather than embedded in source.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prohibit embedding secrets or sensitive data in source code.

degrades

Directly restricts access to source code, preventing exposure of embedded sensitive information.

prevents

Secure coding standards explicitly prohibit hard-coding credentials or sensitive data.

prevents

Classification helps identify source code containing sensitive data so it can be protected.

prevents

Access control limits who can view or retrieve source code that may contain secrets.

prevents

Secure SDLC practices include removing secrets from code before commit or deployment.

mitigates

Environment separation reduces risk of accidental exposure but does not address secrets already in code.
