Access-list技术应用研究

Research on Network Security based on Access-list

访问表是网络防御外来安全威胁的第一关 ,它是通过允许或拒绝信息流通过路由器的接口来实现的一种机制。本文介绍了访问表的基本概念、基本原理以及具有高级安全特性的新一代访问表 ,给出了一个建立应用访问表的实例 ,最后对各种网络安全威胁给出了对策及实现方案。

Access-list is the first pass that prevents from attacks by permitting or denying packets to pass the router's interface.In this paper,the basic concept and theory of access-list is expounded and a new type access-list with advanced security is detailedly discussed,an example of creating and applicating access-list is given ,Finally,the solution of network security is given.
