Advances In System Isolation For Cyber Attack Mitigation
The increasing global availability of broadband access to the Internet has led to the creation and distribution of malicious software and financially-oriented underground economies of criminals. Annual economic loss attributed to malicious software activities is estimated at more than US $10 Billion. Malicious activities are no more limited to single hackers and DDoS attacks, but range from hardware Trojans to more complex insider and outsider attacks in cloud computing systems. These attacks can take down critical infrastructures such as the power grid, financial trading platform or large data centers. Isolation has been one of the most effective solutions in connected SCADA-based systems. However, the practicability of early solutions as well as the need for high-speed communication have prevented a wider adoption of isolation as a means to tackle security. Recently, there has been a resurgence in isolation as a means to mitigate cyber attacks.
In this talk, we introduce and motivate the principle of isolation and it's application to cyber security. Thereafter recent advances in the field will be discussed including efforts currently on the way in academia and industry. The talk will discuss current work at the University of Arkansas, particularly the Isolation and Protection Module (IPM) and the Hardware Sandboxing paradigm. While the IPM provide a system on chip (SoC) solution to enforce isolation in networked systems, hardware sandbox are used in SoC to contain effects of non-trusted IPs.
Dr. Bobda is Professor of Computer Engineering at the University of Arkansas, in Fayetteville, AR. Dr. Bobda received the Licence in mathematics from the University of Yaounde, Cameroon, in 1992, the diploma of computer science and the Ph.D. degree (Summa Cum Laude) in computer science from the University of Paderborn in Germany in 1999 and 2003 respectively. In June 2003 he joined the department of computer science at the University of Erlangen-Nuremberg in Germany as Post doc. In 2005 Dr. Bobda was appointed Assistant Professor at the University of Kaiserslautern, Germany where set the research lab for self-organizing embedded systems that he led until October 2007 before being promoted to Professor at University of Potsdam in 2007. Dr. Bobda led the working Group Computer Engineering at the University of Potsdam until 2010 when he accepted a faculty position as associate professor at the University of Arkansas where he founded the smart embedded systems lab. Dr. Bobda was tenured and promoted to the rank of full professor at the University of Arkansas in 2016.
Dr. Bobda research interests include embedded systems, system on chip and system on FPGA, computer architecture, with application in embedded imaging, high-performance computing and cyber security. Dr. Bobda’s research has been sponsored by multiple national and international organizations including the National Science Foundation (NSF), the Air Force Research Lab, the Navy, the German Research Association (DFG) and the German French University.
Dr. Bobda received the best dissertation award 2003 from the University of Paderborn for his work on synthesis of reconfigurable systems using temporal partitioning and temporal placement, the test 2014 Test of Time Award SBCCI Conference: Task Scheduling for Heterogeneous Reconfigurable Computers, the 2012 HiPEAC Paper Award 2012 at ACM/EDAC/IEEE Design Automation Conference (DAC 2012) in San Francisco, California, June 2012 and the 2011 3rd place Best Paper Awards Fifth ACM/IEEE International Conference on Distributed Smart Cameras (ICDSC 2011)
Dr. Bobda is Senior Member of the ACM and member of the IEEE Computer Society. He is also in the program committee of several conferences (FPL, FCCM, FPT, RAW, RSP, ERSA, RECOSOC, DRS, ICDSC), the DATE executive committee as proceedings chair (2004, 2005, 2006, 2007, 2008, 2009, 2010). He served as reviewer of several journals (IEEE TC, IEEE TVLSI, IEEE TECS, ACM TODES, IEEE TRETS, Elsevier Journal of Microprocessor and Microsystems, Integration the VLSI Journal) and conferences (DAC, DATE, FPL, FPT, SBCCI, RAW, RSP, ERSA, ICDSC, DASIP), as guest editor of the Elsevier Journal of Microprocessor and Microsystems and member of the editorial board of the Hindawi International Journal of Reconfigurable Computing. Dr. Bobda is the author of one of the first most comprehensive books in the rapidly growing field of Reconfigurable Computing.
Dr. Bobda has worked with the ACM student chapter at the University of Arkansas from 2011 to 2015 in the organization of the computer science and computer engineering colloquium as well as the international exchange program. This program has seen the participation of the Technical University of Munich in Germany, the engineering college ESIREM in Dijon, France, the University of Chemnitz in Germany, the Ecole Polytechnique in Cameroon, the University Alianza Popular Revolucionaria in Coyoacán, México. From 2010 to 2014, more than 30 students from the previous listed Universities were hosted as intern in Dr. Bobda’s lab.
Dr. Bobda has published more than 150 papers in leading journals and conferences, has a citation count and his work has been downloaded more than 9000 times.
