Alefiya Hussain presents on Security and Resiliency of CPS Infrastructure at USC’s Center for CPS & IoT

DETER’s Alefiya Hussain presented on CPS domain-specific specializations and her work on evaluating the security and resiliency of CPS infrastructure at the first Mini-Workshop on Cyber-Physical Systems Security and Privacy, held at the USC Viterbi School of Engineering Center for Cyber-Physical Systems and the Internet of Things, on May 2, 2017. Over the past decade, there has become a great interest in developing novel cyber-physical systems and analyzing them with respect to security. There is growing momentum in creating interdisciplinary frameworks that combine key elements of the physical sciences (modeling and dynamics) with computer science (information flow and software) and operations research (optimization and game theory).

Dr. Hussain spoke about her goal to develop a framework to bridge the gap between theory and deployment to make cyber-physical systems robust and resilient to failures. She also discussed the importance of developing methodological guidance and knowledge transfer mechanisms. In particular, one foundational challenge is real-time coupling between testbeds and deployed systems and how to couple them by using virtual time. Another issue is figuring out how to implement control systems in relation to updating state space representations with distributed observers.

Alefiya highlighted her ongoing projects on computational models for resilient natural gas and power networks and hardening network infrastructure for fast, resilient control of power systems. This body of work includes coupled simulations/emulations that use the Information Sciences Institute’s DETER testbed (DETERLab), at the University of Southern California, with an RTDMS (Real Time Dynamics Monitoring System) at the FREEDM Systems Center at NC State University.

Several faculty from the University of Southern California presented their work at the mini-workshop. The list of presenters is below.
