使用ACL技术的网络安全策略研究及应用

Research and Application of Network Security Policies with ACL

ACL基于包过滤技术,广泛应用于路由器上以提高网络安全性。介绍了ACL技术的基本原理、主要功能以及路由器上ACL的配置和访问原则,并以一个实际的网络拓扑为例,详细分析了如何使用ACL技术来实现网络安全问题的防范,给出了相应安全策略的关键配置代码。

ACL, one of packet-filtering technologies, is widely used in the router to improve network security. The paper firstly gives a brief introduction of concept and working principle, main function, collocation and access method of the access control list. Then the paper takes a actual network topology as an example to analyze in detail how to safeguard the network security with ACL technology, and give the key codes of corresponding network security policies.
