The security of CPS has been an international priority because of our dependence on reliable and affordable services provided by these infrastructures such as electric power, water, oil and gas etc. Despite interest of multiple stake holders in this problem, there is still a language barrier between security practitioners and control/operation engineers that limits their potential benefits of their interactions.In this talk the speaker will give an overview of the relationships between security concepts and control theory concepts and then describe approaches where leveraging both areas of research can be used to design novel mechanisms to guarantee CPS security and privacy.
In this talk we first present several examples of vulnerabilities in critical infrastructure such as the power grid, transportation and financial networks, and discuss how these vulnerabilities emerge from an intricate interplay between different layers of such infrastructure: physical, cyber, economic, and social. These vulnerabilities which can lead to large and catastrophic failures can arise from lack of robustness to certain rare disturbances that are completely exogenous, or from an endogenous risk that is created during the natural evolution of the system by utility maximizing agents. We present a control theoretic abstraction for formalising these problems in a unified framework and discuss some of the existing methodologies, challenges, and open problems in addressing security with a focus on rare events and risk in multi-layered safety-critical infrastructure.

Mardavij is a principal research scientist at the Laboratory for Information and Decision systems (LIDS). He received the Ph.D. degree in Aeronautics and Astronautics from MIT (2008), focusing on developing a control theoretic framework for verification of software systems.Between 2008 and 2011 he held postdoctoral and research scientist positions at LIDS. His main research interests include distributed and networked control systems, software and finite-state systems, and dynamics and economics of power systems with an emphasis on robustness and risk. He is a recipient of the 2007 AIAA graduate award for safety verification of real-time software systems.
