Mitigating Controls (NIST 800-53 r5) AI

AC-16 Security and Privacy Attributes good match

Associating and preserving security attributes (including permissions) with objects reduces the chance they are lost or weakened on copy/restore/share.

AC-3 Access Enforcement partial match

Enforcing approved authorizations for access directly stops objects from receiving or retaining less-restrictive permissions than intended.

AC-6 Least Privilege partial match

Least-privilege assignments limit the blast radius when permissions are incorrectly relaxed during copy/restore/share operations.

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

Enforcing least-privilege permission policies and reviews directly prevents incorrect permission propagation on copy/restore/share operations.

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.5.15 Access control partial match
degrades

Access-control policy defines how permissions must be preserved when objects are copied or shared.

A.5.18 Access rights partial match
degrades

Access-rights provisioning and review processes directly address the risk of overly permissive copied objects.

A.8.2 Privileged access rights partial match
degrades

Privileged-access management includes rules for maintaining correct permissions on copied or restored data.

A.8.3 Information access restriction partial match
degrades

Information-access-restriction controls enforce least-privilege permissions that must be preserved during copy/restore operations.
