基于协同组的校园信息系统安全模型研究

Research on the Security Model of Campus-wide Information Systems Based on Cooperative Group

针对目前校园网的安全问题进行分析,通过研究现有防御技术及主流的内网安全策略,结合一般高校的关键业务流范型,找到了一种可以实现校园网"安全性、可控性、高效性"三个发展目标的方法。即通过软硬件手段,构建基于三层协同组的校园网信息系统安全模型。本模型的特点是提高了校园网的整体运行效率,发挥了终端信息系统CPU的作用并实现了终端的自动维护。最后通过蠕虫防御仿真对比实验验证了该模型在安全防御中的性能优势。

To make real the aims of ＂security, controllability, efficiency＂ of campus network, a novel securitymodel based on three-layer cooperative group is proposed. This model improved the efficiency of campus network, made full use of the CPU of terminal information system, and realized the auto-maintenance of terminals. Experiment result on simulation of worm defense shows the model＇s effectiveness.
