VPN技术是利用有关密码学知识在开放的公共网络上建立虚拟专用网络的技术。随着应用服务模式从C/S结构向Web的迁移,企业必须面对一个新的挑战,即不影响最终用户使用的前提下,实现在任何地方灵活地访问应用服务。SSL VPN(Secure Socket Layer Virtual Private Network)利用SSL的加密特性来进行访问控制,可以很好地解决了上述问题。 VPN technology is the use of knowledge of cryptography in the open public network to establish a virtual private network technology. As the application service model migrates from the C / S structure to the Web, enterprises have to face a new challenge of providing flexible access to application services anywhere without compromising end-user usage. SSL VPN (Secure Socket Layer Virtual Private Network) The use of SSL encryption for access control, can be a good solution to the above problems.
