基于路由器访问表的网络安全研究

Research on the security of network based on the access control lists of a router

研究了在路由器上建立访问表来提高网络安全性的方法 ,针对蒙骗过滤、阻止探测、保护关键端口、保护路由器以及限定对特定地址的访问等问题提出了相应的对策 。

In this paper, method of establishing access control lists on a border router to avoid attacking on network by using access control lists is analyzed and discussed. Aiming at IP spoofing, denying exploring, protecting the key port, protecting the routers and restricting access to special addresses, corresponding strategy and concrete configuration commands are suggested.
