Advanced Security Assurance Case Based on ISO/IEC 15408

Assessment and assurance of conformity with regulation documents assumes significant cost in modern economies. Demonstration of compliance with security standards involves providing evidence that the standards' security criteria are met in full substantiating appropriate decision.
