摘要：随着越来越多的校园网投入运行和接入Internet，教育信息化、校园网络化作为网络时代的教育方式和环境，各高校网络规模的急剧膨胀，网络用户的快速增长，使得校园网网络安全变的重要。校园网安全问题也已经成为当前各高校网络建设中不可忽视的首要问题。作为开放网络的组成部分，校园网也面临着病毒泛滥、非法攻击、未授权访问、盗用网络资源、内部信息非法窃取等一系列安全问题。本文针对校园网面临的安全威胁以及应对的手段进行了探讨。
校园网的网络安全问题如：通信光缆、电缆、电话线、局域网、远程网等都有可能遭到破坏，从而引起校园网络的瘫痪，影响正常教学业务；恶意用户利用校园网内邮件服务器系统；服务器的攻击和利用TCP/IP协议簇的安全漏洞以及校园网中不合理的网络拓扑结构进；黑客的入侵和各病毒的侵害以及构建安全防火墙系统。本文通过对校园网的安全风险分析，提出了网络安全防范和校园网建设的对策。

With the fact that more and more campus covering bringing into service as with a net and switching in Internet, education informationize, the network-rization campus education way as network times and environment, every colleges and universities network scale rapidness expands , cybernaut's fleetness increases by, changeable importance of feasible campus net network safety. Safe campus net problem becomes also already the first problem being not allowed to ignore currently in every colleges and universities network construction. As the network ingredient opening to the outside world, a series of safe problem such as the campus net being attacked be in flood , illegal being also confronted with a virus , not have authorized the network resource , inside information to visit, being embezzling to steal illegally. The means threatening the main body of a book and answering specifically for safety facing the
Campus net network safety problem such as: It both possibility such as optical cable , cable , telephone line , local area network , long-range net communicating by letter is met with destroy, arouse the network paralysis of campus thereby, business affecting regular teaching; The evil intention consumer makes use of campus net inner mail server system; Unreasonable in the leak and campus net attacking and making use of TCP/IP agreement cluster safety server network topology structure moves forward; Invasion and every virus's hacker encroachment and structure build safe fire prevention wall system. Safe risk analysis the main body of a book is passed to campus net, have suggested that the network safety keeps watch the countermeasure preparing campus covering construction as with a net.
