SVM approach with a genetic algorithm for network intrusion detection

Abstract

Due to the increase in unauthorized access and stealing of internet resources, internet security has become a very significant issue. Network anomalies in particular can cause many potential problems, but it is difficult to discern these from normal traffic. In this paper, we focus on a Support Vector Machine (SVM) and a genetic algorithm to detect network anomalous attacks. We first use a genetic algorithm (GA) for choosing proper fields of traffic packets for analysis. Only the selected fields are used, and a time delay processing is applied to SVM for considering temporal relationships among packets. In order to verify our approach, we tested our proposal with the datasets of MIT Lincoln Lab, and then analyzed its performance. Our SVM approach with selected fields showed excellent performance. © Springer-Verlag Berlin Heidelberg 2005.
