摘　　要：防火墙技术已成为近年来保护计算机网络安全的技术性措施。它是位于两个信任程度不同的网络之间的软件或硬件设备的组合。文章从防火墙技术具体实现原理上,介绍工作在开放系统互联(OSI,Open System Interconnection)参考模型网络层的网络级防火墙、工作在 OSI 参考模型应用层的应用级网关、工作在 OSI 参考模型会话层的电路级网关和状态检测防火墙。The firewall technology has become protects the computer network security in recent years the technical measure.It is located at between two trust degree different network the software or the hardware equipment's combination.This article realizes in specifically the principle from the firewall technology,introduced the network level firewall worked in Open System Interconnecfion reference model's network layer,the application level gateway worked in OSI reference model's application layer,the electric circuit level gateway and the condition examination firewall worked in the OSI reference model's conversation level.

关 键 词：OSI参考模型 防火墙 网关
