Intrusion Detection with Support Vector Machines and Generative Models
Date: September 30 - October 02, 2002
This paper address the task of detecting intrusions in the form of malicious attach on programs running OD a host computer system by inspecting the trace of system calls made by these programs. We use ‘attack-tree’ type generative models for such intrusions to select features that are used by a Support Vector Machine Classifier. Our approach combines the ability of an HMM generative model to handle variable-length strings, i.e. the traces, and the non-asymptotic nature of Support Vector Machines that permits them to work well with small training sets.
