Mitigating Controls (NIST 800-53 r5) AI

SC-6 Resource Availability good match
prevent

Directly limits resource consumption caused by incomplete cleanup (CWE-459) in Tanium Connect before exhaustion occurs.

SC-5 Denial-of-service Protection partial match
prevent

Provides denial-of-service protections that mitigate the uncontrolled resource consumption vulnerability in Tanium Connect.

SI-4 System Monitoring partial match
detect

Enables monitoring of system resources to identify anomalous consumption stemming from the Tanium Connect flaw.

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-06 mostly match
prevents

Secure-development practices and coding standards normally require proper resource release and cleanup.

ID.AM-08 partial match
prevents

Life-cycle management encompasses disposal of temporary resources but does not specifically target runtime cleanup bugs.

PR.DS-10 partial match
prevents

Explicitly calls for removing sensitive data after use, directly addressing one class of incomplete cleanup.

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.8.10 Information deletion full match
degrades

Explicitly requires secure deletion of temporary or residual data, directly addressing incomplete cleanup.

A.8.25 Secure development life cycle partial match
prevents

SDLC practices include cleanup steps, yet the weakness can still occur if those steps are omitted.

A.8.28 Secure coding partial match
prevents

Secure-coding rules can mandate explicit cleanup of temporary resources, but do not guarantee it.

A.8.32 Change management partial match
detects

Change-management processes may require cleanup verification, but the control itself does not address the weakness.
