Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Enforces access control policies so an app cannot read the sensitive data used for user fingerprinting.

AC-6 Least Privilege good match
prevent

Restricts each app to the minimum privileges required, eliminating unnecessary access to fingerprinting data.

AC-4 Information Flow Enforcement partial match
prevent

Mediates information flows between apps and system resources to block unauthorized exposure of the sensitive identifiers.

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.PS-01 full match
prevents

Hardened baselines and configuration management explicitly require correct default file permissions.

PR.AA-05 mostly match
prevents

Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.

ID.AM-08 partial match
prevents

Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.

PR.PS-06 partial match
prevents

Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.

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.8.9 Configuration management mostly match
prevents

Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
