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.

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

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

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