Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover incomplete cleanup through dynamic analysis or resource-leak testing.

SI-14 Non-persistence good match

Non-persistence mechanisms explicitly initiate resources in a known state and terminate them, directly enforcing cleanup.

AC-12 Session Termination partial match

Session termination forces explicit release of session-related temporary resources.

SC-4 Information in Shared System Resources partial match

Preventing unintended information transfer through shared resources requires complete cleanup of those resources.

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
finds

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