Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-12 Cryptographic Key Establishment and Management good match

Requiring cryptographic keys to be established and managed according to defined requirements prevents developers from embedding static unchangeable keys.

IA-5 Authenticator Management good match

Authenticator management requires secure distribution and handling of credentials, structurally discouraging hard-coded values.

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.

PR.AA-01 partial match
blocks

PR.AA-01's credential/key-management processes can reduce the incentive to embed secrets but do not address or detect hard-coded values in source code, so the weakness remains fully possible.

PR.DS-01 partial match
blocks

Data-at-rest protection policies require proper key management and therefore discourage hard-coded keys.

PR.DS-02 partial match
blocks

Data-in-transit protection similarly depends on non-hard-coded keys for encryption.

PR.PS-01 partial match
blocks

Configuration baselines and reviews can prohibit hard-coded keys in deployed artifacts.

PR.PS-06 partial match
blocks

Secure-SDLC activities such as code review and secret scanning directly prevent embedding static keys.

PR.AA-02 none match
blocks

PR.AA-02 addresses human identity proofing and per-person credential issuance at enrollment; it has no bearing on whether developers embed static credentials in software.
