SC-24 Fail in Known State good match

Enforces failure to a known state while preserving required properties, limiting impact of unhandled exceptions.

SI-17 Fail-safe Procedures good match

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

SA-8 Security and Privacy Engineering Principles partial match

Requires application of security engineering principles that include robust exception and error handling during design.

SI-11 Error Handling partial match

Requires generation of safe, actionable error messages that directly addresses proper handling of exceptional conditions.
