用Internet代替租用专线以节省费用——这是一种VPN策略思想。有了强大的加密和认证手段,新的基于硬件的盒子就能够在大多数公用网络上传输秘密信息。但正由于充分考虑了安全性,牺牲了其它一些性能。在对六种基于硬件的VPN设备进行选择时,发现所有设备都能够应付安全方面的挑战,能够抵抗两百多种攻击。并且在大多数情况下,对设备进行远程管理都非常容易。但性能到底如何呢?事实证明是存在问题的,尤其是以T1或较高的速率进
Save money by replacing the leased line with the Internet - a VPN policy idea. With powerful encryption and authentication tools, new hardware-based boxes can transmit confidential information on most public networks. However, due to full consideration of the safety, sacrificing some other performance. When choosing from six hardware-based VPN appliances, it was discovered that all devices were able to meet security challenges and resist more than two hundred attacks. And in most cases, remote management of equipment is very easy. But what about performance? Facts have proved problematic, especially at T1 or higher rates
