Independent Co-Assurance using the Safety-Security Assurance Framework (SSAF): A Bayesian Belief Network Implementation for IEC 61508 and Common Criteria

This addresses the challenge of combining safety and security compliance for critical systems, but it is incremental as it builds on existing frameworks.

The paper applied the Safety-Security Assurance Framework (SSAF) to integrate safety and security standards IEC 61508 and Common Criteria, using a Bayesian Belief Network implementation to enable independent co-assurance.
