Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Mandates use of cryptography to protect sensitive information, preventing its unencrypted storage in environment variables.

SC-28 Protection of Information at Rest good match

Requires confidentiality protection (typically encryption) for information at rest, directly stopping cleartext storage of sensitive data in environment variables.

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.DS-01 partial match

blocks

Encryption and related protections for data-at-rest directly prevent cleartext env-var storage of secrets.

PR.PS-01 partial match

blocks

Hardened configuration baselines and management practices reduce the chance of secrets being left in environment variables.
