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-01 mostly match
prevents

Credential management practices directly enforce re-authentication for password changes.

PR.AA-03 mostly match
prevents

Authentication requirements include verifying identity before allowing credential modifications.

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.5.17 Authentication information partial match
degrades

Requires secure management of authentication information, directly addressing the need to verify the original password before allowing a change.

A.8.5 Secure authentication partial match
prevents

Mandates secure authentication mechanisms, which include verifying existing credentials before permitting password changes.

A.5.16 Identity management none match
none

Identity management processes can incorporate verification steps, but the control itself does not explicitly require password-change verification.

A.8.3 Information access restriction none match
none

Information access restriction can be strengthened by password verification, yet the control focuses on access rights rather than change procedures.
