2、应。本论文介绍了入侵检测系统及其检测原理,并在此基础上,采用 模块化设计思想,设计并实现了一个网络入侵检测系统。本论文详细介绍了入侵 检测系统的几大功能模块的实现过程。在入侵事件检测模块中,本软件采用了一 种基于协议分析的规则匹配的方法,对简单的模式匹配法做了改进,极大的提高 了系统的效率。 关键词:网络安全 入侵检测系统 BPF 过滤器 网络协议 规则匹配 Abstract With the rapid expansion of the internet, the electronic commerce is also developing like a raging fire. But t
3、he network security event occurs now and then, which brought the very big loss for the electronic commerce economy. Electronic business has had to solve the network security problem first to insure its continuing rapidly developing. Intrusion detection technology takes an important aspect of the net
4、work security technology. Its development will certainly impel the electronic commerce advance. NIDS (Network Intrusion Detection System) is one important classification of Intrusion Detection System. NIDS can provide a real-time network detection and response. This paper gives an introduction of th
5、e Intrusion Detection System and its detecting principle, and upon this foundation, we use the modular design thought, design and realize a Network Intrusion Detection System. This paper gives details of the realization process of Network Intrusion Detection Systems several function modules. In the
6、intrusion event detection module, we adopt an approach of rule-matching based on protocol analysis, which has made an improvement to the simple pattern-matching approach, and enormously enhanced the efficiency of system.
