Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires FIPS-validated or NSA-approved cryptographic algorithms, preventing the use of weak algorithms that enable decryption of sensitive data.

prevent

Mandates cryptographic protection for data in transit, mitigating exposure when weak algorithms are employed by the software.

prevent

Requires cryptographic protection of information at rest, addressing the risk of sensitive data decryption due to weak algorithms.

PR.DS-01 partial match
prevents

PR.DS-01 promotes encryption for data-at-rest but never requires strong algorithms, leaving CWE-327 fully possible; the weakness is also far broader than data-at-rest so one narrow control removes none of its total risk.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.

prevents

Mandating approved algorithms, cipher strength and usage standards directly stops the selection of broken or weak cryptographic primitives that attackers can exploit.

prevents

The explicit call-out of cryptography-related legal constraints (import/export, key escrow, digital-signature validity) reduces the likelihood that an organization will adopt broken or non-compliant cryptographic algorithms that violate those rules.

prevents

Access to current specialist guidance and early vulnerability alerts enables timely replacement of broken or risky cryptographic algorithms with stronger alternatives.
