首先对入侵检测系统的相关技术进行了深入地讨论和分析,并系统阐述了常见网络攻击手段和防范措施,对入侵防御系统的现状和发展方向论述,并详细叙述了入侵防御系统总体设计方案。形成了一种入侵防御系统的预取模型。通过实验分析,该系统能针对不同种类攻击而对系统实现多方位的信息安全保护,很大程度上提高了受保护网络系统的安全性。 Firstly, the related technologies of intrusion detection system are discussed and analyzed in depth. The common means of network attacks and preventive measures are expounded systematically. The status quo and development direction of intrusion prevention system are discussed. The overall design of intrusion prevention system is described in detail. Formed a kind of intrusion prevention system prefetch model. Through experimental analysis, the system can achieve multi-directional information security protection for different types of attacks and largely improve the security of the protected network system.
