Enhancing Cyber-Resilience in Cyber-Physical Systems of Systems:A Methodical Approach

Abstract: Cyber-physical Systems of Systems (CPSoS) are becoming increasingly prevalent across sectors such as Industry 4.0 and smart homes, where they play a critical role in enabling intelligent, interconnected functionality. Addressing the challenges and resilience requirements of these complex environments, we propose a modified Cyber-Resilience Life-Cycle as a practical framework for sustainable risk mitigation. Our approach enhances the adaptability of CPSoS and supports resilience against evolving system complexities and potential disruptions. We conclude by outlining application scenarios for the modified life-cycle and highlighting its relevance in fostering cyber-resilience in operational systems.
