Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-285 CWE-552

Authorization checks via training and content reviews ensure only approved information is released to public systems.

addresses: CWE-285 CWE-552

Documenting access to processing and storage locations helps ensure correct authorization for information resources.

addresses: CWE-285 CWE-552

Requiring explicit approval for maintenance activities and component removal enforces proper authorization for critical system operations.

addresses: CWE-285 CWE-552

Procedures enforce authorization rules for media handling, making unauthorized actions harder to perform without detection.

addresses: CWE-285 CWE-552

Limiting media access to authorized parties addresses improper authorization for resource access.

addresses: CWE-285 CWE-552

The control requires authorization mechanisms and senior approval to prevent unauthorized viewing or alteration of the plan.

addresses: CWE-285 CWE-552

Mandates authorization checks so public access cannot perform disallowed operations or modifications.

addresses: CWE-285 CWE-552

Decoys identify and block exploitation of improper authorization by providing monitored targets that mimic protected functions.

PR.AA-05 mostly match
prevents

PR.AA-05 mostly prevents CWE-285 via enforced policy, reviews, and least-privilege authorization decisions, yet CWE-285 remains only partially prevented because code-level check omissions or errors can still occur outside that single control.

PR.IR-01 mostly match
prevents

Logical segmentation and access protections stop external parties from reaching files that should remain internal.

PR.PS-06 mostly match
prevents

Secure SDLC practices catch and eliminate most authorization defects before release, yet a single broad outcome cannot address every design, role, and runtime facet of CWE-285.

PR.AA-01 partial match
prevents

PR.AA-01 supplies managed identities and access-request workflows that can support downstream authorization decisions, yet does nothing to enforce or verify authorization checks inside a product, leaving CWE-285 fully unaddressed by this control alone.

PR.DS-01 partial match
prevents

Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.

PR.PS-01 partial match
prevents

Hardened configuration baselines commonly include file-system permission settings that limit external access.

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.

prevents

Granular, policy-driven assignment of permissions and dynamic enforcement of those permissions prevent the incorrect or missing authorization decisions that lead to improper authorization flaws.

prevents

By requiring documented authorization rules and periodic policy reviews, the control makes it less likely that authorization decisions will be omitted or implemented inconsistently across applications.

mitigates

By tracing and retrieving all copies of information stored on endpoint and portable devices, the control reduces the likelihood that files remain accessible outside the organization’s security perimeter.

mitigates

Labeling information according to its sensitivity and specifying corresponding protection measures makes it less probable that files or directories containing sensitive content will be left accessible to external parties.

prevents

Mapping access rights to information classification and business requirements forces correct enforcement of authorization decisions, blocking the incorrect authorization weakness at the policy and implementation stage.

finds

Independent reviewers evaluate whether authorization logic matches policy, thereby reducing the window in which incorrect or missing authorization checks remain in production.
