Abstract:
Recent cyber-attacks targeting control and monitoring systems for critical infrastructures has revealed vulnerabilities frequently present in networked control systems. In fact, control systems are often designed to satisfy performance and safety constraints, without regard to security. In this talk, we discuss the application of control-theoretic methods to model and counteract certain classes of cyber-attacks on networked control systems. First, we introduce a security index, which quantifies the inherent level of security against targeted, malicious false-data injection attacks in feedback loops. We illustrate how to compute the index, and how it is used to localize especially vulnerable components in large-scale systems. We also show how the index determines the attacks that are possible to isolate and identify, and those, which are not. Finally, we introduce an optimal security allocation problem for control systems. Here we select components to protect to maximize security, subject to a budget constraint.

Henrik Sandberg is Professor at the Department of Automatic Control, KTH Royal Institute of Technology, Stockholm, Sweden. He received the M.Sc. degree in engineering physics and the Ph.D. degree in automatic control from Lund University, Lund, Sweden, in 1999 and 2004, respectively. From 2005 to 2007, he was a Post-Doctoral Scholar at the California Institute of Technology, Pasadena, USA. In 2013, he was a visiting scholar at the Laboratory for Information and Decision Systems (LIDS) at MIT, Cambridge, USA. He has also held visiting appointments at the Australian National University and the University of Melbourne, Australia. His current research interests include security of cyber-physical systems, power systems, model reduction, and fundamental limitations in control. Dr. Sandberg was a recipient of the Best Student Paper Award from the IEEE Conference on Decision and Control in 2004, an Ingvar Carlsson Award from the Swedish Foundation for Strategic Research in 2007, and Consolidator Grant from the Swedish Research Council in 2016. He leads the Center for Resilient Critical Infrastructures (CERCES) at KTH, has served on the editorial board of IEEE Transactions on Automatic Control, and is currently Associate Editor of the IFAC Journal Automatica.
