| 摘 要： | 随着Intemet网络安全问题的不断暴露和当前黑客攻击技术日益进步，人们逐渐认识到防火墙、数字签名和加密技术这些被动式、静态的防御技术越来越难于保证网络的安全。因此，主动式、动态地保护网络安全的入侵检测系统(Intrusion Detection System，IDS)已成为网络安全发展的一个新方向。本文主要介绍IDS中的数据包截获及解析关键技术。

| Abstract: | With exposure of the net security problem and increasing progress of the attack technology by hackers, more and more people know these passive and static defending technology such as firewall,figure signature and encryption technology can hardly guarantee net security. So intrusion detection system(IDS) which protects net security actively and dynamicly has become a new developing trend of net security. The paper introduces mostly crucial technology about capture and decoding of packet in IDS. |
