网络安全与防火墙技术研究

随着Internet的迅速发展,网络安全问题日益严重。解决网络安全问题的重要手段就是防火墙技术。对防火墙技术的基本概念和系统结构进行简单的介绍,讨论了实现防火墙的两种主要技术手段:一种是基于分组过滤技术(Packet filtering);一种是基于代理技术(Proxy)。最后对防火墙的未来发展趋势进行了简单的介绍。

Network Security and Firewall Technology Research

With the rapid development of Internet and network security issues is becoming increasingly serious. Resolve the issue of net-work security is an important means of firewall technology. In this paper,the basic concept of firewall technology and system architecture,discussed the firewall to achieve the two main technical means: A packet filtering technology is based on (Packet filtering); one is based onagent technology. Finally,the firewall for the future development trend of a brief introduction.
