Previous works in the area of computer network security have emphasized the creation of Intrusion Detection Systems (IDSs) to flag malicious network traffic and computer usage. Raw IDS data may be correlated and form attack tracks, each of which consists of ordered collections of alerts belonging to a single multi-stage attack. Assessing an attack track in its early stage may reveal the attacker’s capability and behavior trends, leading to projections of future intrusion activities. Behavior trends are captured via Variable Length Markov Models (VLMM) without predetermined attack plans. A virtual terrain schema is developed to model network and system configurations, and used to estimate critical elements and vulnerabilities exposed to each attacker given his/her progress. In addition, the virtual terrain can be used to assess the effect of cyber attacks. This proactive approach to estimate future attack actions in an online manner is pioneering and critical for critical network and computing infrastructure, and has been highly recognized by the United State Air Force Research Laboratory. This talk will present our past work and recent advances in combating against cyber attacks.


Shanchieh Jay Yang was born in Taipei, Taiwan in 1973. He received his BS degree in electronic engineering from the National Chiao-Tung University in Taiwan in 1995, and his MS and Ph.D. degrees in electrical and computer engineering from the University of Texas at Austin in 1998 and 2001, respectively. He is currently an associate professor in the Department of Computer Engineering at Rochester Institute of Technology in Rochester NY, USA. In summer 2005, he was selected as a Visiting Research Faculty for Air Force Research Laboratory, Rome NY. He has authored and co-authored more than 35 refereed articles in areas including networking, autonomous robots, information fusion, and haptics. His current research interests focus on impact assessments of cyber and terrorist attacks, security and privacy issues for sensor-cloud and opportunistic computing, as well as cooperative and autonomous robots. Prof. Yang is a Co-Director of the Networking and Information Processing Laboratory at RIT, and an active member of the Center for Multisource Information Fusion (CMIF) based in western New York. He was a chair for IEEE Joint Communications and Aerospace Chapter in Rochester NY in 2005, and the chapter was recognized as an Outstanding Chapter of Region 1. He has participated in the development of a multidisciplinary Ph.D. program in Computing and Information Science at RIT. He received Norman A. Miles Award for Academic Excellence in Teaching in 2007 and TxTEC Graduate Fellowship in 1999. He has been on the organization committees for IEEE Upstate NY Workshop on Communications and Networking from 2004 to 2007, ISIF/IEEE International Conference on Information Fusion in 2009, and 2011 International Conference on Social Computing, Behavioral-Cultural Modeling, & Prediction. He has also been a reviewer for numerous journals and conferences, including IEEE/ACM Transaction on Networking, IEEE Transaction on Information Forensics and Security, IEEE INFOCOM, IEEE ICC, IEEE Globecom, IEEE MILCOM, and IEEE MASS.
