Mitigating Controls (NIST 800-53 r5) AI

AC-24 Access Control Decisions good match

Requiring access-control decisions to be applied to each request ensures no alternate path can bypass authorization checks.

AC-25 Reference Monitor good match

A reference monitor that is always invoked by definition covers every possible path, eliminating the root cause of unprotected alternate paths.

AC-3 Access Enforcement good match

Enforcing approved authorizations for every logical access request structurally blocks unprotected alternate paths to restricted resources.

PR.AA-05 mostly match
prevents

Enforcing and reviewing authorizations across all access paths directly prevents alternate-path bypasses.

PR.IR-01 partial match
prevents

Logical segmentation and unauthorized-access protections reduce the attack surface of unprotected alternate paths.

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.8.2 Privileged access rights mostly match
prevents

Privileged access rights must be enforced on every possible route to privileged functions.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can discover unprotected alternate paths before release.

A.8.3 Information access restriction mostly match
prevents

Information access restriction mechanisms must close all alternate paths to restricted data or functions.

A.5.15 Access control partial match
prevents

Access control policy directly requires protection of all entry points to restricted functionality.

A.5.18 Access rights partial match
prevents

Managing access rights must cover every alternate path that could bypass intended restrictions.

A.8.20 Networks security partial match
mitigates

Network security can limit some alternate paths but is not the primary control for application-level path protection.
