The College of Computer and Information Science presents a Hiring Talk by:

Alvaro Cardenas, University of California, Berkeley 
Wednesday, April 22 - 11:00am
366 West Village H

Title:
Statistical Models for Anomaly Detection

Abstract:
In this talk I will present new statistical models for different problems in computer security.
The first half of the talk will focus on network anomaly detection. I will show how statistical methods and game theory can help practitioners understand and design better anomaly detection schemes in the face of intelligent and adaptive attackers. I will also describe the Bayesian Receiver Operating Characteristic (B-ROC) curves, and I will explain how they can be used as a tool to interpret the classification accuracy of intrusion detection systems.

In the second half of the talk I will present some of my ongoing work in two different fields: the cybercrime ecosystem and the security of cyber-physical systems.  In particular, I will show how to use statistical techniques to extract information and model parts of the computer underground market. I will also show how a mathematical model of the physical world can be used to detect computer attacks against cyber-physical systems, and to design attack-resilient control algorithms.
