虚拟专网网络边界信息安全问题研究

本文首先阐述了虚拟专网产生的背景以及主要技术,着重分析了虚拟专网的体系结构以及网络边界结构组成,之后从定性和定量两个角度阐述虚拟专网边界安全的评估方法,通过以上分析提出三类边界防护策略,用以提升虚拟专网业务支撑、网络覆盖、安全防护和信息保密能力。

This paper first expounds that the background and main technologies of virtual private network,emphatically analyzes the architecture of virtual private network and the composition of network boundary structure,then expounds the evaluation method of virtual private network boundary security from the qualitative and quantitative perspectives,and puts forward three kinds of border protection strategies.This function improves the service support,network coverage,security protection,and information confidentiality capabilities of virtual private networks.
