用于网络安全教学课堂实时演示的虚拟化系统

摘要

采用虚拟化技术，在一台物理计算机上虚拟多台计算机和多个网络，能够在多媒体教室用一台机器对网络安全教学中涉及的大量内容进行实时演示。设计了一个用于网络安全教学课堂实时演示的虚拟化系统VS4NST，给出了该系统的架构和各组件的配置情况，概要描述了数据包嗅探、IPSec、VPN、SQL注入、CA等教学内容的演示方法。在不同配置的物理计算机上的运行实验表明，VS4NST可被目前广泛使用的中低端个人计算机所承载，验证了该系统的普遍适用性。%With virtualizing technology, a physical computer could simulate many computers and networks on it, so the contents in network security teaching can be demoed on the computer in multimedia classroom. VS4NST, a virtual system for network security teaching is designed for live demo in classroom. The architecture and the configuration of components are given, and the demo procedures of network package sniffing, IPSec, VPN, SQL injection, CA etc. are described. The test running in physical computers with different configuration of hardware shows that VS4NST could be hosted by middle or low class of personal computer, so it is universally applicable.
