Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations for logical access to stored information, directly stopping unauthorized read/write.

SC-28 Protection of Information at Rest good match

Requires protection of confidentiality/integrity for information at rest, directly addressing insecure storage.

AC-6 Least Privilege good match

Limits privileges so only authorized accesses to sensitive stored data are permitted.

AC-16 Security and Privacy Attributes partial match

Associates security attributes with information to support proper access decisions on storage.

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.AA-05 mostly match
prevents

Enforces least-privilege permissions and authorization reviews that limit read/write access to stored sensitive data.

PR.DS-01 mostly match
prevents

Directly protects data-at-rest confidentiality via encryption or access controls that prevent unauthorized reads.

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.

A.7.10 Storage media none match
mitigates

Secure reuse and disposal procedures, including cryptographic wiping and physical destruction, stop the insecure storage of sensitive data on media that may later be accessed by unauthorized actors.

A.7.14 Secure disposal or re-use of equipment none match
prevents

Mandating secure disposal techniques stops the insecure retention of sensitive information on storage media that leaves organizational control.
