防火墙技术研究与应用

在Internet高速发展的同时，如何同步保障网络安全，是个很重要的问题，而防火墙技术正是基于这一问题而进行研究，防火墙技术的核心思想是在不安全的Internet环境中构造一个相对安全的子网环境。本文从防火墙的基本特性入手，主要分析防火墙体系结构及它的实现技术，最后探讨防火墙的选择、配置、应用原则。

Firewall Technology Research and Application

The rapid development of the Internet,how to synchronize to ensure network security, is a very important issue,and firewall technology is based on this research problem,firewall technology, the core idea is in an insecure environment of the Internet to construct a relatively secure subnet environment.In this paper, the basic firewall features to start,the main analysis of the firewall architecture and its implementation techniques,the final choice of a firewall,configuration,application principles.
