摘要： 针对现有的集中式网络监控系统存在的不足，设计并实现一种网络安全监控系统，系统采用层次结构，将监控功能分散到各个受控终端的监控Agent上，减轻监控服务器的工作负荷和对网络带宽的需求，实现对网络实时安全监控。对监控Agent的设计与系统实现进行了分析讨论。应用表明，系统具有良好的灵活性和可扩展性。

Abstract: This paper points out the deficiencies of the existed centralized network monitor system, a network security monitor system is designed and implemented. This system takes hierarchical structure and distributes monitor functions to monitor agents located in terminals so as to lighten the load of monitor server and network and realize real-time security monitor of network. The design of monitor agents and the implementation of the system are discussed. Applications show that the system is flexible and extendable.

Key words: network security monitor, hierarchical structure, agent
