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.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices directly prohibit embedding secrets or sensitive data in source code.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Directly restricts access to source code, preventing exposure of embedded sensitive information.
Secure coding standards explicitly prohibit hard-coding credentials or sensitive data.
Classification helps identify source code containing sensitive data so it can be protected.
Access control limits who can view or retrieve source code that may contain secrets.
Secure SDLC practices include removing secrets from code before commit or deployment.
Environment separation reduces risk of accidental exposure but does not address secrets already in code.
