虚拟机在网络安全实验教学中的应用

虚拟机技术在计算机中的应用越来越广泛。利用虚拟机技术可以高效、快速、低成本地搭建复杂的网络环境，特别是在网络安全方面，无论是在评估网络模型性能，病毒分析系统，还是网络环境模拟方面，虚拟机技术都发挥着关键性的支撑作用。文中介绍了如何利用VMware的网络安全工具虚拟机高效快捷地实现全套的网络安全实验。实践结果表明，通过NST完全可以在有限的单机资源上模拟复杂的网络环境，并实现网络攻防过程的演示教学。

Applications of Virtual Machine in Network Security Experiment Teaching

Virtual machine technology is used more and more widely in computer applications. The complicated net-work environment could be built up effectively, fast and cheaply with virtual machine technology, especially in network security field. The virtual machine technology would play an important support role in performance evaluation of network model￡^-virus analysis system and simulation of network environment, the virtual machine technology. This article describes how to effectively implement complete network security experiments by using VMware Network Security Toolkit （NST）. The experimental results show that NST could fully simulate the complicated network environment and implement the demonstrative teaching of attack and defence process on the limited resources of a single physical machine.
