Mitigating Controls (NIST 800-53 r5) AI

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

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

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

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

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

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.

prevents

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