Detection theory and its applications to computer security.
Most of the theory and results of signal processing were obtained under the assumptions of relatively benign scenarios. In signal processing we usually assume specific properties of the signal or the noise. These assumptions--while not valid at all times--may model the system accurately enough for most practical purposes. However, when we apply signal processing tests for computer security problems, we face an intelligent opponent who will try to exploit any of our erroneous assumptions. In this course we will study how and when to apply detection theory algorithms to computer security problems.
General overview of detection theory, Neyman-Pearson theory, sequential detection, and change detection algorithms. It will also cover some basic game theoretic concepts that will be applied in future lectures.
21 Giugno, 9:00 - 11:00, aula I (edificio principale della Facoltà)
The second lecture will apply game theory to the detection problem with the goal of modeling the adversary and obtain provably-secure detection algorithms. These algorithms will be applied to problems in MAC-layer protocol misbehavior, intrusion detection, and watermarking.
22 Giugno, 9:00 - 11:00, aula I (edificio principale della Facoltà)
The third lecture will describe how to combine multiple classifiers in order to maximize the area under the ROC curve metric. We will then present practical examples in machine learning and intrusion detection that can benefit from these multiple classifier combinations.
24 Giugno, 9:00 - 11:00, aula I (edificio principale della Facoltà)
The final lecture will cover miscellaneous topics and some of my current research, including metrics and how to evaluate classifiers, autoregressive models for clustering and anomaly detection, and detection of anomalies in critical infrastructures.
