特征选择和分类器优化耦合的网络入侵检测
NIU Lei, et al. Network intrusion detection based on considering features selection and classifier optimization simultaneously
摘要
Abstract
In order to solve mismatch problem of the feature selection and classifier parameters in network intrusion, this paper proposes a network intrusion detection model(F-SVM)based on coupling feature selection with classifier optimization. The evaluated standard of features is mapped into high-dimensional space by radial basis kernel function to calculate, and the rela-tion between the network feature evaluation and network intrusion classifier is established, so the feature selection stage has solved the parameter design of the classifier, the network intrusion detection model is established and the performance is tested using KDD 99 data. The results show that F-SVM can eliminate unnecessary, redundant features, dimension of network charac-teristics is significantly reduced, and the optimal parameters of network intrusion classifier are obtained, which improves the net-work intrusion detection accuracy and detection efficiency.关键词
