Trust Environment for Cyber-Physical Systems: The DYNAMO Approach

Abstract

This paper explores the evolving landscape of cybersecurity within cyber-physical systems, emphasizing the critical need for resilience and trust-building mechanisms. Grounded in the foundational perspectives of Cybersecurity Science, the study addresses the challenges posed by the complex interdependencies among physical, information, cognitive, and social domains. It introduces the DYNAMO platform, a novel approach that integrates Cyber Threat Intelligence (CTI) with Business Continuity Management (BCM) to enhance situational awareness and recovery planning. The platform's comprehensive methodology spans existing tool incorporation, detailed assessments, identification of gaps, simulations, and knowledge generation. Furthermore, the paper delves into the intricacies of cybersecurity information sharing, advocating for a unified approach to combat hybrid threats. The establishment of a common operational picture and shared situational awareness emerges as pivotal, underlining the indispensable role of technology, social trust, and resilience in securing critical information-sharing mechanisms in cyber-physical systems.
