融合邻域粗糙集与粒子群优化的网络入侵检测
Network intrusion detection algorithm based on neighborhood rough set and PSO
摘要
Abstract
The intrusion detection data contains large redundant and noisy features, as well as some continuous attributes. This paper presents an algorithm based on neighborhood rough set and Particle Swarm Optimization algorithm for the effect of intrusion detection. Training subset is reduced by using neighborhood rough set, and new training subset is generated. The redundant attributes and noise are eliminated to avoid information loss when using traditional rough set;parameters of Support Vector Machine are optimized using particle swarm algorithm to avoid the risk of low precision by subjective choiced parameters. It improves the performance of the intrusion detection. The simulation results in the KDD99 dataset show that the algorithm can effectively improve the accuracy and efficiency of intrusion detection. It has high generalization and stability.关键词
