校园数字教学资源的VPN准入模式的探讨及实现

Campus VPN Access to Digital Teaching Resources and the Realization of Model

随着教育信息化应用的迅速发展,高校的教学资源日渐丰富。很多学校都提供了VPN远程访问数字资源的功能,解决校园网内部资源访问受IP地址限制的问题。但VPN准入模式与校园网络认证、数字资源及网络安全密切相关。通过对多种VPN软硬件准入模式的分析、试验,实现了支持灵活的基于证书、智能卡的客户端认证方法,允许通过在VPN虚拟接口上应用防火墙规则实现用户及组访问控制策略的安全、方便、快捷的准入方案。

With the rapid development application of information technology education,the resources of university teaching are more abundant.Many universities offer a VPN remote access to digital resources;solve the internal resources of the campus network to access the IP address constraints.However,access mode and the campus VPN network authentication,digital resources and network security are closely related.VPN hardware and software through a variety of access pattern analysis,testing,implementation to support flexible based on certificates,smart card,and the client authentication method,allowing the VPN virtual interface through the application of firewall rules to implement user and group security access control policies,convenient and quick access to programs.
