计算机网络安全课程虚拟实验室建设

Construction of Computer Network Security simulation laboratory

以Packet Tracer 5.3.2仿真软件为基础,构建了计算机网络安全虚拟实验室,介绍了Packet Tracer 5.3.2仿真软件提供的网络安全技术;以广域网安全实验为例,从终端安全接入、无线局域网加密技术、路由器身份鉴别、访问控制列表和基于上下文的访问控制等方面论述了广域网安全实验的内容,通过实验拓扑结构的设计和IP地址规划、安全协议的配置和实验结果测试等步骤完成仿真实验;旨在锻炼学生设计、配置和测试网络安全的能力,加深对计算机网络安全理论和概念的掌握和理解。

The Computer Network Security simulation laboratory was constructed by Packet Tracer5.3.2 simulation software. The network security technology of Packet Tracer5.3.2 was introduced, and the contents of the wide area network security experiment were discussed in the aspects of the terminal security access, wireless local area network encryption techniques, router authentication, access control list and context-based access control. The experiment was accomplished by designing the network structure and planning IP address, configuring security protocol and testing experiment result. The skills for students to design, configure and test the network security are supposed to be exercised by this simulation experiment so as to better master and understand the computer network security theory and concept.
