VPN

A VPN, or virtual private network, most often is used to create an encrypted "tunnel" that allows users to pass sensitive data across the public Internet. (Technically, VPNs can be used to create tunnels within a private network for special status, security-related or otherwise.) The effect to users is logging onto the network remotely, as if they were physically connected. Two types of VPN technology dominate the market: IPSec VPNs, which are based on client-installed software, and SSL VPNs, which are Web-browser based.
