Mitigating Controls (NIST 800-53 r5) AI

AC-2 Account Management good match

AC-2 directly requires defining, assigning, and controlling user accounts throughout their lifecycle, structurally preventing improper user management.

IA-4 Identifier Management good match

IA-4 mandates authorized management of user identifiers, stopping the creation or retention of unmanaged user identities.

PS-4 Personnel Termination partial match

PS-4 enforces timely disabling and removal of access upon termination, addressing a key failure mode of incorrect ongoing user management.

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

Directly addresses management of user identities and credentials throughout their lifecycle.

PR.AA-05 mostly match
prevents

Covers policy-driven definition and review of user permissions and entitlements.

PR.AA-02 partial match
prevents

Supports proper user onboarding by binding verified identities to credentials.

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.5.16 Identity management mostly match
prevents

Identity management directly governs the full lifecycle of user accounts, preventing incorrect user management.

A.5.18 Access rights mostly match
prevents

Access rights provisioning and de-provisioning ensure users are correctly created, modified, and removed.

A.6.5 Responsibilities after termination or change of employment mostly match
prevents

Responsibilities after termination or change of employment address removal of user access but not ongoing user management.

A.8.2 Privileged access rights mostly match
prevents

Privileged access rights assume correct user accounts exist; the control does not manage user creation or removal.

A.5.15 Access control partial match
prevents

Access control policies rely on accurate user management but do not themselves define user lifecycle processes.

A.8.3 Information access restriction partial match
mitigates

Information access restriction depends on properly managed users but does not address user management itself.
