A Virtual Private Network (VPN) is a network technology that creates a secure network connection over a public network such as the Internet or a private network owned by a service provider. Large corporations, educational institutions, and government agencies use VPN technology to enable remote users to securely connect to a private network.
A VPN can connect
multiple sites over a large distance just like a Wide Area Network
(WAN). VPNs are often used to extend intranets worldwide to
disseminate informatioyen and news to a wide user base. Educational
institutions use VPNs to connect campuses that can be distributed
across the country or around the world.
In order to gain access
to the private network, a user must be authenticated using a unique
identification and a password. An authentication token is often used
to gain access to a private network through a personal identification
number (PIN) that a user must enter. The PIN is a unique
authentication code that changes according to a specific frequency,
usually every 30 seconds or so.
