基于增益比的机器学习自适应分层入侵检测方法

Adaptive Layered Approach using Machine Learning Techniques with Gain Ratio for Intrusion Detection Systems

Heba Ezzat Ibrahim, Sherif M. Badr, Mohamed A. Shaheen

摘要:

入侵检测系统(IDS)已成为计算机和网络系统的一个重要问题。入侵检测系统的性能优化是一个重要的开放性问题,越来越受到研究界的关注。为了提高入侵检测的效率和分类率,本文设计并实现了一种多层入侵检测模型,有效地应用机器学习技术(C5决策树、多层感知器神经网络和朴素贝叶斯),利用增益比为每一层选择最佳特征,从而使用更小的存储空间,获得更高的入侵检测性能。实验结果表明,基于C5决策树的多层模型,采用基于增益比的特征选择,分类精度更高,虚警率比MLP和朴素贝叶斯更低。使用增益比显著提高了三种机器学习技术(C5、MLP和朴素贝叶斯)的U2R和R2L的准确性。MLP在使用Dos和Probe层的全部41个特征时具有较高的分类率。

英文摘要:

Intrusion Detection System (IDS) has increasingly become a crucial issue for computer and network systems. Optimizing performance of IDS becomes an important open problem which receives more and more attention from the research community. In this work, A multi-layer intrusion detection model is designed and developed to achieve high efficiency and improve the detection and classification rate accuracy .we effectively apply Machine learning techniques (C5 decision tree, Multilayer Perceptron neural network and Naïve Bayes) using gain ratio for selecting the best features for each layer as to use smaller storage space and get higher Intrusion detection performance. Our experimental results showed that the proposed multi-layer model using C5 decision tree achieves higher classification rate accuracy, using feature selection by Gain Ratio, and less false alarm rate than MLP and naïve Bayes. Using Gain Ratio enhances the accuracy of U2R and R2L for the three machine learning techniques (C5, MLP and Naïve Bayes) significantly. MLP has high classification rate when using the whole 41 features in Dos and Probe layers.
