Katia Système's Alice Sentin Discusses MBSE for Cybersecurity in Complex Systems

🎬 The video features Alice Sentin, Product Portfolio Manager for cybersecurity and safety at Katia Système, discussing model-based system engineering (MBSE) applied to cybersecurity for complex systems like vehicles and aircraft. The discussion highlights the use of SysML and the newer Ramel (Risk Analysis and Assessment Modeling Language), standardized by the OMG in June 2024, to integrate cybersecurity into system design. Key industries addressed include automotive (regulated by UN R155 and ISO 21434) and aeronautics (DO-326A), where tools like Katia Magic Cyber Security Designer enable risk modeling, threat identification, and compliance with sector-specific standards. The approach emphasizes collaborative supply chain integration, with tier-1 and tier-2 suppliers contributing to holistic risk assessments, and aims to bridge design and operational phases through digital twins and real-world attack simulations. Upcoming regulations like the EU Cyber Resilience Act (December 2027) will mandate cybersecurity lifecycle management for digital products, reinforcing the need for proactive risk modeling. The conversation underscores the shift from reactive patching to security-by-design, citing examples like the 2015 Jeep Cherokee hack and Tesla vulnerabilities as catalysts for industry transformation.
