VPN是网络安全非常重要的一个组成部分,在现代各个单位中得到了越来越广泛的应用,它提出了一种远程接入的方案,有效的解决了现代各个企业之间异地部门的安全通信问题。随着VPN技术的不断发展,在应用层提出的VPN解决方案显出了很大优势,安全、灵活、便捷的特性,使它成为了网络安全中有着非常重要地位的方案之一。本文重点研究与探讨了点对点模式。在系统点对点工作模式的讨论上,又着重讨论了应用层VPN网关的设计问题,例如隧道技术在数据包中转发的问题和虚拟网卡等,然后提出了一种新的解决思路,在一定程度上使得VPN的安全性得以提高。
VPN is a very important part of network security. It has been applied more and more widely in all modern units. It proposes a remote access solution that effectively solves the problem of secure communication between different enterprises in different places problem. With the continuous development of VPN technology, the VPN solution proposed at the application layer shows a great advantage. Its security, flexibility and convenience make it one of the most important solutions in network security. This article focuses on research and discussion of the point-to-point mode. In the point-to-point working mode of the system, the discussion focused on the application layer VPN gateway design issues, such as the tunnel technology in the packet forwarding issues and virtual network adapter, and then proposed a new solution ideas, to some extent VPN security is improved.
