FEATURE SELECTION AND COMPARISON OF CLASSIFICATION ALGORITHMS FOR INTRUSION DETECTION

Abstract

The increase in the frequency of use of the Internet causes the attacks on computer networks to increase. Such phenomena alsoincrease the importance of intrusion detection systems. In this paper, KDD Cup 99 dataset is used for the classification of thenetwork attacks. Four different classification algorithms were used, and the results were compared. These algorithms weremultilayer perceptron network, decision trees, fuzzy unordered rule induction algorithm (FURIA) and support vector machines.The most successful algorithm in this dataset found as FURIA. As the second part of this study, the most important feature setswere found by correlation-based feature selection and best first search algorithm. Then, the results of classification algorithmswere compared with these new feature sets according to the performance of the algorithms.
