Intranet White Papers
Stretching 'VPN' to Fit Web-Based Intranets?
Overview
When the VPN market first emerged, nearly every discussion on the topic started with a question: What is a virtual private network? Over the past two years, I've seen rough consensus form around the following definition: a secure network service, riding over shared infrastructure, but with the same properties we associate with private networks. That is, access limited to authenticated users, protection against eavesdropping and data modification, and ability to define and enforce service levels.
To many, "VPN" also implies a tunneling protocol: PPTP, L2TP, IPsec, perhaps even SSH. Others disagree, saying VPNs enable services—secure remote access, site-to-site Intranet, or business-to-business Extranet—and tunnels are merely one way of supporting VPN services.
