A B S T R A C T Intrusion detection systems (IDSs) deal with large amounts of data containing irrelevant and/or redundant features. These features result in a slow training and testing process, heavy computational resources, and low detection accuracy. Features selection, therefore, is an important issue in IDSs. A reduced features set improves the system accuracy and speeds up the training and testing process considerably. In this paper propose a wrapper-based feature selection techniques by using Great Deluge algorithm (GDA) asthe search strategy to specify a candidate subset for evaluation, as well as using Support Vector Machine (SVM) as the classifier technique. The experiments used four random datasets collected from KDD-cup99. Each data set contains around 4000 records. The performance of the proposed technique has been evaluated based on classification accuracy by comparing with other feature selection techniques such as Bees Algorithm (BA), Rough-DPSO, Rough, Linear Genetic Programming (LGP), Support Vector Decision Function Ranking (SVDF), and Multivariate Regression Splines (MARS). The result shows that the feature subset produced by GDA yield high classification accuracy when compared with other techniques.
