The aim of this study is to simulate a network traffic analyzer that is part of an Intrusion Detection System - IDS, the main focus of research is data mining and for this type of application the steps that precede the data mining : data preparation (possibly involving cleaning data, data transformations, selecting subsets of records, data normalization) are considered fundamental for a good performance of the classifiers during the data mining stage. In this context, this paper discusses and presents as a contribution not only the classifiers that were used in the problem of intrusion detection, but also the initial stage of data preparation. Therefore, we tested the performance of three classifiers on the KDDCUP'99 benchmark intrusion detection dataset and selected the best classifiers. We initially tested a Decision Tree and a Neural Network using this dataset, suggesting improvements by reducing the number of attributes from 42 to 27 considering only two classes of detection, normal and intrusion. Finally, we tested the Decision Tree and Bayesian Network classifiers considering five classes of attack: Normal, DOS, U2R, R2L and Probing. The experimental results proved that the algorithms used achieved high detection rates (DR) and significant reduction of false positives (FP) for different types of network intrusions using limited computational resources.
