Experience and Lessons Learned: Cybersecurity Compliance of Industrial Control Systems Base on IEC62443-4-2 Testing (D11a)
This study assesses the cybersecurity compliance of 20+ Industrial Control Systems (ICS) against the IEC 62443-4-2 standard, focusing on component-level security within critical infrastructures. The talk highlights methodologies such as Communication Robustness Testing (CRT) and Software Bill of Materials (SBOM) analysis to identify vulnerabilities, evaluate software dependencies, and benchmark cybersecurity resilience. Key insights reveal common gaps, best practices, and areas for improvement to strengthen critical infrastructure security.
