Colloquium - Vigna

Designing a Web of Highly-Configurable Intrusion Detection Sensors
University of California, Santa Barbara
3/6/2003
3:30pm-4:30pm

Intrusion detection relies on the information provided by a number of sensors deployed throughout the monitored network infrastructure. Sensors provide information at different abstraction levels and with different semantics. In addition, sensors range from lightweight probes and simple log parsers to complex software artifacts that perform sophisticated analysis. Managing a configuration of heterogeneous sensors can be a very time-consuming task. Management tasks include planning, deployment, initial configuration, and run-time modifications. This talk describes a new approach that leverages off the STAT model to support a highly configurable sensing infrastructure. The approach relies on a common sensor model, an explicit representation of sensor component characteristics and dependencies, and a shared communication and control infrastructure. The model allows an Intrusion Detection Administrator to express high-level configuration requirements that are mapped automatically to a detailed deployment and/or reconfiguration plan. This approach supports automation of the administrator tasks and better assurance of the effectiveness and consistency of the deployed sensing infrastructure.

Giovanni Vigna is an Assistant Professor in the Department of Computer Science at the University of California in Santa Barbara. His current research interests include network and computer security, intrusion detection systems, security of mobile code systems, penetration testing, and distributed systems. He is Program Chair of the International Symposium on Recent Advances in Intrusion Detection (RAID 2003). Giovanni Vigna received his MS with honors and PhD from Politecnico di Milano, Italy, in 1994 and 1998, respectively. His PhD research focused on mobile code architectures and mobile code security issues. He is a member of IEEE and ACM.

Refreshments will be served immediately following the talk in ECOT 831.
