Ph.D. Research

My master's research in intrusion detection led into a project run by Drs. Johnny Wong, Vasant Honavar, and Les Miller. The Intelligent Multi-Agents for Intrusion Detection and Countermeasures Project seeks to research and develop a prototype intrusion detection system based on distributed knowledge networks. In our intrusion detection model, distributed, mobile, intelligent agents clean and gather data from hosts and networks, record and fuse the data, classify the data at various levels, and use data mining and data warehousing to develop knowledge from the data.

The project ran from 1998 to 1999 in the Department of Computer Science at Iowa State University and was funded by the U.S. Department of Defense.

Our prototype implementation is written nearly completely in Java and uses  ObjectSpace's Voyager Object Request Broker for mobile, autonomous agents.
