Title: Control and Game-Theoretic Methods for Secure Cyber-Physical Systems

Abstract:  In this talk, we will focus on security and resilience issues of cyber-physical systems; platforms with tightly interconnected physical and digital components. By employing tools from control and game theory, the talk will revolve around two main axes: initially, we will approach the security problem from an abstract viewpoint and leverage the theory of bounded rationality to develop realistic models of attacker behavior, facilitating the construction of defending strategies based on historical data. Subsequently, we will focus on control-theoretic methods of proactive and reactive security of physical components in cyber-physical systems via a switching-based Moving Target Defense framework, designed to be used alongside a learning inspired attack detector. Finally, we will showcase our current and future research directions focusing on further investigation of behavioral models for security in multi-agent systems and the use of control-theoretic principles in secure wireless communications.
