Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces access permissions on Tanium Threat Response resources so that incorrect defaults (CWE-276) cannot expose sensitive data.

AC-6 Least Privilege good match
prevent

Requires least-privilege permission assignments at creation time, eliminating the overly permissive defaults that caused the information disclosure.

SC-28 Protection of Information at Rest partial match
prevent

Mandates cryptographic or access-control protection of information at rest, mitigating disclosure when file or directory permissions are set incorrectly.

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.

Hardening callouts derived

Configuration rules from DISA STIG baselines that reduce the attack surface for weaknesses of the type cited by this CVE. Derived transitively via CVE→CWE→STIG over `controls_xwalks` (authoritative rows only).
