网络安全课程教学云平台的设计与实现

The Design and Implementation of Cloud Platform for Network Security Course Teaching

传统的网络安全课程实验教学环境一般是基于真实的物理网络环境,这或将对网络环境造成一定的影响,因此我们设计了一款基于云计算的网络安全课程教学平台。首先,该平台根据网络安全课程教学体系设计需求,虚拟出多样化的灵活且易扩展的实验环境;其次,平台上的实验过程是可逆的,对真实的网络环境没有影响,这样就改进了传统的网络安全课程实验教学环境对真实的物理网络环境的影响。经过一学年的教学实际验证,我们设计的基于云计算的网络安全课程教学平台,可以让学生轻松地在平台上创建进行并个性化的虚拟实验,学生的动手实践能力提高了,对理论知识的理解也更加深刻,授课教师更不需担心学生虚拟实验会对网络环境造成影响。

The traditional experiment teaching environments of the network security course are generally based on real physical network environment,which are likely to influence on the real physical network environment.Therefore,this paper designs and implements a teaching platform for network security course based on cloud computing.First,the platform virtualizes a diverse,flexible and scalable experimental environment based on the requirements of teaching system of the network security course.Second,the experimental processes on the designed platform are reversible,and the real network environment will not be affected by the experimental processes.This approach improves the impact of the traditional experiment teaching environment of the network security course on the real physical network environment.After the actual verification of teaching in the past year,the students can easily create and conduct their virtual experiments on the designed platform for network security course teaching beased on cloud algorithum.Through the experiments,the hands-on practical skills of the students are improved,and their understanding totheoretical knowledge is also more profound.On the other hand,the instructors do not need to worry about that the student virtual experiment will have an impact on the network environment.
