Mitigating Controls (NIST 800-53 r5) AI

SC-24 Fail in Known State good match

Requires the system to fail to a known safe state on specified failures, limiting the impact of unhandled exceptional conditions.

SI-17 Fail-safe Procedures good match

Mandates explicit fail-safe procedures triggered by indicated failures, structurally preventing unhandled or mishandled exceptional conditions.

SI-11 Error Handling partial match

Requires generation of appropriate error messages on exceptional conditions, directly enforcing correct handling rather than silent or incorrect behavior.

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 SDLC practices explicitly require proper exception and error handling during design and coding.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance verifies correct handling of exceptional conditions.

A.5.37 Documented operating procedures partial match
degrades

Documented operating procedures may specify exception handling but do not guarantee implementation.

A.8.15 Logging partial match
finds

Logging captures unhandled exceptions, aiding detection but not preventing the weakness.

A.8.16 Monitoring activities partial match
finds

Monitoring can surface unhandled exceptions but does not enforce proper handling.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates exception-handling requirements and testing that directly prevent improper handling of exceptional conditions.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly include handling of error and exceptional conditions.
