Title: Cooperative Autonomous Resilient Defense Platform for Cyber-Physical Systems

Mohamed Eltoweissy, Ph.D.

Abstract: Cyber-Physical Systems (CPS) entail tight coupling and coordination of cyber and physical resources. Emerging CPS promise significant enhancements in the safety, efficiency and reliability of numerous systems ranging from national security and defense, to smart infrastructure systems in energy, healthcare and transportation, to worldwide social interactions and gaming. Enhanced CPS resilience and defense intelligence are precursors to fulfilling the CPS promise. To this end, our work aims to:

* Achieve asymmetric advantage to CPS defenders, prohibitively increasing the cost for attackers;

* Ensure resilient operations in presence of persistent and evolving attacks and failures; and

* Facilitate defense alliances, effectively and efficiently diffusing defense intelligence and operations transcending organizational boundaries.

In this talk,I will present CyPhyCARD (Cooperative Autonomous Resilient Defense platform for Cyber-Physical Systems) - a distributed, dynamically configurable and programmable platform that manages a large number of cyber and physical resources and services upon which evolutionary defenses can be built to achieve the aforementioned goals. CyPhyCARD synergistically integrates: (1) A novel biologically-inspired construction of adaptive system building blocks; (2) management of multi-dimensional software diversity and hot shuffling of software variants; and (3) a system of virtual/physical sensors and effectors

Following an overview of CyPhyCARD, I will discuss in more detail how CyPhCARD mitigates the threat inherent in monolithic software. CyPhyCARD possesses a set of platform-managed capabilities that employ multidimensional software diversity to, in effect; induce spatiotemporal "Software Behavior Encryption (SBE)" for trace resistance and moving target defense. The key principles are: (1) decoupling functional roles from runtime role players; (2) devising intrinsically-resilient composable online-programmable building blocks; (3) separating logic, state and physical resources; and (4) employing functionally-equivalent, behaviorally-different code variants. Nodes autonomously and cooperatively change their SBE policies both proactively and reactively according to the continual changes in context and environment. Using analysis and simulation, results show that we can encrypt the execution behavior by inducing confusion and diffusion at a reasonable overhead.

Bio: Mohamed Eltoweissy is a Professor of Computer and Information Sciences at Virginia Military Institute. He is also affiliate Professor in The Bradley Department of Electrical and Computer Engineering at Virginia Tech. Prior to VMI, Eltoweissy served as Chief Scientist for Secure Cyber Systems at the Pacific Northwest National Laboratory. He also served on the faculty of Virginia Tech and James Madison Universities. Eltoweissy's current interests crosscut the areas of cyber/cyber-physical systems security and resilience, cooperative autonomic systems, and networking architecture and protocols for large-scale ubiquitous cyber-physical systems. Eltoweissy has over 160 publications in archival journals and respected books and conference proceedings and a funding record exceeding $15M. He also serves on the editorial board of IEEE Transactions on Computers (the flagship and oldest Transactions of the IEEE Computer Society), as well as other reputable journals. In addition, he is active as an invited speaker at both the national and international levels. While at James Madison University, Eltoweissy was nominated for the Virginia SCHEV Outstanding Faculty Awards, the highest honor for faculty in Virginia. Eltoweissy is a senior member of IEEE and ACM.
