Cisco路由器的安全配置
现在大多数的企事业单位和部分连Internet网，一般都是一台路由器与ISP连接实现。这台路由器就是交换外部Internet和内部网络的桥梁，假如这台路由器可以合理进行安全设置，那么就可以对内部的网络提供一定安全性或对已有的安全多了一层屏障。(Nowadays, most enterprises and institutions and some parts of the Internet are connected to the Internet by a router and an ISP. This router is the bridge between the external Internet and the internal network. If the router can be properly set up for security, it can provide a certain degree of security to the internal network or add a layer of barrier to the existing security.)
