由于校园网规模的增大,网络内外部攻击变多,本文将介绍利用ACL技术来搭建安全校园网环境。本文先论述了ACL的概念、ACL的工作原理与规则及ACL的分类,而后介绍了如何设计ACL规则,配置校园网的访问控制列表,来实现一套可行的校园网安全解决方案。 Due to the increase of the size of the campus network, more attacks inside and outside the network, this article will introduce the use of ACL technology to build a secure campus network environment. This article first discusses the concept of ACL, the working principle and rules of ACLs, and the classification of ACLs. Then it introduces how to design ACL rules and configure the access control list of campus networks to implement a set of feasible campus network security solutions.
