Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation activities can exercise concurrent paths and resource contention to discover deadlock conditions before deployment.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles applied during design can incorporate synchronization ordering, timeouts, and resource hierarchies that structurally avoid deadlock formation.

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 partial match
prevents

Secure SDLC practices can include concurrency analysis and lock discipline to avoid deadlock conditions.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect deadlock conditions through stress and concurrency testing.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle requires deadlock analysis and avoidance techniques during design and coding.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles include concurrency controls and resource-locking discipline that prevent deadlock.

A.8.28 Secure coding partial match
prevents

Secure coding standards mandate safe lock ordering, timeouts, and deadlock detection patterns.

A.8.32 Change management none match
none

Change management may catch deadlock-related defects during reviews but does not directly address concurrency design.
