Networking - VPN - Remote Site Connectivity Fundamentals A Virtual Private Network (VPN) supplies network connectivity over a potentially long physical distance. In this respect, a VPN is a form of Wide Area Network (WAN). VPNs enable file sharing, video conferencing and similar network services. A VPN can work over both public networks like the Internet and private business networks. Using a method called tunneling, a VPN runs over the same hardware infrastructure as existing Internet or intranet links. VPN technologies includes various security mechanisms to protect these virtual connections. Virtual private networks generally don't provide any new functionality that isn't already offered through alternative mechanisms, but a VPN implements those services more efficiently and cheaply in most cases.
