VPN Security


VPN (Virtual Private Network) is a generic term used to describe a communication network that uses any combination of technologies to secure a connection tunnelled through an otherwise unsecured or untrusted network1.Instead of using a dedicated connection, such as leased line, a "virtual" connection is made between geographically dispersed users and networks over a shared or public network, like the Internet. Data is transmitted as if it were passing through private connections.
