本文对软件定义网络的技术背景和应用现状进行了综合性研究。通过对在新型网络环境下职业院校的信息化网络安全问题的分析,针对当前由于职业院校信息化程度越来越高带来的信息化系统安全管理复杂度不断提高,以及在云计算背景下细粒度网络安全管理难以实现的问题,提出了一种基于软件定义网络技术构建的新型职业院校信息化网络安全管理模式,并设计了基于该模式的职业院校信息化安全管理系统,以实现在复杂的职业院校信息化网络环境下,为职业院校提供有效的、全方位、细粒度的网络安全管理服务。
This paper makes a comprehensive study of the technical background and application status of software-defined networks. Through the analysis of the problem of information network security in vocational colleges under the new network environment, in view of the fact that the complexity of security management of information system brought by the increasing degree of informationization in vocational colleges is constantly increasing, Aiming at the problem that the fine-grained network security management is difficult to be realized, a new type of information network security management model based on software defined network technology is proposed and the informational safety management system of vocational college based on this model is designed. To achieve the complexity of vocational colleges in the information network environment, for vocational colleges to provide effective, comprehensive, fine-grained network security management services.
