访问控制列表在校园网的应用

Access Control Application in the Campus Network

访问控制列表是一种应用在路由器接口上的包过滤技术,其在网络设备接口上读取和分析数据包头中的信息,与自身设置的策略进行比对,进而控制数据流的转发或者阻塞。访问控制列表在网络安全防范中扮演着极为重要的角色。首先介绍了访问控制列表的一些基本原理,接着结合东莞理工学院校园网的实际情况,介绍了访问控制列表技术在校园网应用中的一些技巧。

Access Control List is a kind of packet filter technology applied in the interface of routers,and it reads and analyses from the interface of network equipments the information stored in data packet head and then compare with the strategy set by itself,thus control the transmission and blocking of data stream.Since Access Control List plays a most important role in the protection of network security,this paper introduces some basic theory of Access Control List and some techniques required in the using process of Access Control List technology in the application of campus network according to the real situation of the campus network of Dongguan University of Technology.
