The overwhelming majority of engineered systems in use today are highly dependent on computation and communication resources. This includes systems at all levels, ranging from vehicles to large-scale industrial systems and national critical infrastructures. The resilience of the computational systems and infrastructures underlying these technologies is of great importance for mission continuity and success. Resilience, in this context, is understood as the ability of a system to anticipate, withstand, recover, and evolve from cyber attacks and failures. In this symposium we will focus on the topic of resilience of cyber systems. Among others, the concepts of cyber awareness, anticipation, avoidance, protection, detection, and response to cyber attacks will be promoted and will help set the tone of the event. A better understanding and development of these concepts and its supporting technologies will help provide some of the key underlying capabilities for the design and development of resilient cyber systems.
