随着近几年网络攻击的事故频频出现,其影响范围越来越广泛,入侵检测作为一种主动的安全防御手段,通过对网络上的数据流进行实时分析,发现潜在的入侵威胁,最大限度地提高网络的安全保障能力。文章在分析入侵检测系统概念的基础上,设计并分析了基于网络的入侵检测系统的主要模块,并指出了入侵检测系统的不足与发展趋势。
With the frequent occurrence of cyberattacks in recent years and its wider and wider scope of influence, intrusion detection as a proactive security defense means real-time analysis of the data flow on the network to find out the potential threat of intrusion and to maximize To improve the network security capabilities. Based on the analysis of the concept of intrusion detection system, this paper designs and analyzes the main modules of network-based intrusion detection system and points out the shortcomings and development trend of intrusion detection system.
