摘 要: 代理服务器通过在应用层上控制进出网络的权限使网络服务得到监控,因此可以取代或增强网络防火墙的功能。分析了代理服务器的工作原理,提出了两种典型的基于代理服务器的Intranet防火墙方案,并以实例讨论了其实现方法。 Proxy servers supervise network services through controling the accesses to the protected networks on the application layer,so that they can replace or enhance the network firewalls.In this paper,the working principle of proxy servers is analyzed.Two typical kinds of Intranet firewalls based on proxy servers are proposed, and the implementation method is discussed through a case study.
