基于IPSec与基于SSL的VPN的比较与分析

为了保障VPN传输私有数据的安全性，需要特定的安全技术用于创建和维护VPN网络。目前有几种安全技术得到了较广泛的应用，每种技术都有自己的优点，同时也存在一定的不足。针对其中两种较多采用的VPN技术——基于IPSec协议的VPN和基于SSL协议的VPN，从应用范围、使用的复杂性、安全性以及可扩展性等几个方面对其进行一番比较和分析，并概括出根据实际需求选择合适的VPN的参考标准。

Comparison and analysis of IPSec-based and SSL-based VPN

In order to ensure the security of the private data transferring through VPN, some special security technologies were needed to create and maintain the networks. Several of these technologies have already been widely used nowadays. Each of them has its advantages and disadvantages. Aiming at two technologies which are IPSec-based WN and SSL-based WN, several aspects such as the field of application, management complexity, security and scalability were compared and analyzed, and a reference about how to choose the appropriate VPN technology was summarized.
