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.

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.PS-06 mostly match
prevents

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

PR.DS-01 partial match
prevents

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

PR.DS-02 partial match
prevents

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

PR.PS-01 partial match
prevents

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

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.

A.8.24 Use of cryptography partial match
prevents

Key-management controls that govern generation, rotation and protection of keys make the use of embedded hard-coded cryptographic keys less likely and easier to detect.
