Research on LAN Network Security of Enterprises

随着计算机网络技术的飞速发展,计算机网络已经成为人们活动中不可缺少的一部分。网络的规模不断扩大,其拓扑结构也日益复杂。与此同时,网络的安全问题也成为紧迫的问题。特别对于企业而言,如何保护其内部的局域网不受侵犯是规划网络时必须要考虑的问题。文章首先分析了网络安全问题的现状,指出了网络侵犯的典型类型,然后结合一个实例描述了建立完善的企业网络安全的策略。

With the development and application of Internet/Intranet,computer network plays a very important role in our society.Much larger the network has been scaled,much complexes its topology is.At the same time ,network security has become an urgent problem all over the world.How to protect the intrusion to the Intranet,especially for the enter-prises,must be considered when authors begin to design the network.This paper first analyzes the status of the network security and points the main types of the network intrusion,then describes the policy for establishing the perfect securi-ty of the enterprise's network through combining an example.
