数字校园网络立体化安全防护的研究

Research on Digital Campus Three Dimensional Network Security Protection

校园网络安全隐患很多,对高校教育信息化应用带来了诸多不便,数字校园的安全需要综合考虑信息安全管理、物理安全、网络安全、主机安全、应用安全等多方面的因素,因而迫切需要建立一个立体化的安全防御体系。文中介绍了数字校园立体信息安全的建设思路,详细分析了内控外防、认证相辅的实现技术和外网出口的安全防御方案,在重点业务核心区域采用层次防御、审计相随的层次化安全防范技术。在多校区管理中,实现整网延伸、安全可信的校园网络信息安全建设原则,构建了按区域、分层次的多校区校园网稳定、安全的体系架构。实现了整体的立体安全防护效果,实践效果达到了网络信息安全的防护作用。

Many campus network security risks bring a lot of inconvenience for information technology applications in education college, digital campus security needs to take various factors into account including information security management,physical security,network security,host security,application security,and thus it is an urgent need to establish a three-dimensional security defense system. In this paper,introduce the three-dimensional digital campus information security building ideas,detailed analysis of implementation techniques of the internal control and external defense,certification complementary and external network security defense export program,the focus of the core business area using hierarchical attendant prevention technology with hierarchical defense and security audit. In multi-campus management,the realization of the entire network extension,safe and reliable campus network information security principles,construct a regional,multi-tiered architecture of campus network with stability and security. Achieve the overall three-dimensional defense effects, practice effect reaches the protection purpose for network information security.
