Mitigating Controls (NIST 800-53 r5) AI

SC-12 Cryptographic Key Establishment and Management good match

Key establishment and management requirements force use of approved RNG sources with adequate entropy when generating keys.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles can include selection of strong entropy sources during design.

SC-13 Cryptographic Protection partial match

Mandating approved cryptographic algorithms and modules inherently requires sufficient entropy for random values and 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 practices explicitly include vetted RNG and entropy sources, directly preventing this weakness while covering many other development concerns.

PR.AA-03 partial match
prevents

Password-strength policies implicitly require sufficient entropy, but the control addresses authentication rather than algorithmic randomness.

PR.DS-01 partial match
prevents

Proper encryption for data-at-rest requires sufficient entropy for keys/nonces; eliminating the weakness therefore supports but does not fully realize the control.

PR.DS-02 partial match
prevents

Cryptographic protection of data-in-transit depends on adequate entropy; the weakness directly undermines the control's effectiveness.
