Virtual Private Network At Your Benefits Posted By: Jhon Phill

By admin • December 11th, 2009

“A VPN is a generic term that describes any combination of technologies that can be used to secure a connection through an otherwise unsecured or untrusted network.”

Virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or individual users with secure access to their organization’s network. A virtual private network can be contrasted with an expensive system of owned or leased lines that can only be used by one organization.

A VPN enables you to send data between two computers across a shared or public inter network in a manner that emulates the properties of a point-to-point private link. The act of configuring and creating a virtual private network is known as virtual private networking.

Packets that are intercepted on the shared or public network are indecipherable without the encryption keys. The portion of the connection in which the private data is encapsulated is known as the tunnel. The portion of the connection in which the private data is encrypted is known as the virtual private network (VPN) connection.
