Understanding VPN Service Powered By Docstoc
					VPN or virtual private network is a secure network that mainly relies on infrastructure for
public telecommunication such as the Internet, to provide access to a central network.
The connection uses an encrypted system, as an option when contacting websites. It gives
remote offices or users who are constantly on the move, easy access. The VPN service
requires the remote users who are part of the network to be authenticated. The encryption
technology helps to prevent unauthorized parties from accessing private information.

VPN has many functions including data sharing and access to resources from the
network. Other services include websites, printers and databases among others. A user
will typically experience the central network the same way as being directly connected to
the central network. The use of the VPN technology through the Internet has meant that it
is no longer necessary to acquire expensive telecommunication installations.

Using VPN service and technology helps to reduce costs because the need for physical
lines has been removed, and is no longer necessary for remote users. The basic concept is
that the World Wide Web is used to transmit the messages, yet the same security
available when dealing with a personal computer is available. The VPN providers often
use one of two systems to setup the network connection. There are those who install the
VPN connection as an extra connection on the computer control panel. Others use a
downloadable file that the user can install to make the configuration. Those who are not
familiar with the networks opt for the latter option.

When users communicate using the Internet, the connection or VPN will encrypt the data,
to make sure that it is not read by just anyone who happens to intercept it. The VPN
server on the other end of the communication, takes the message and forwards it to the
appropriate recipient. When the server makes the connection, the recipient is only able to
see the servers IP address, and not that of the sender. This means that the message
remains anonymous when it is in the service. The server does not retain any logs that can
be traced to the sender.

The service providers allow users to explore the Web without worrying about who may
be trying to trace them. Sensitive data can remain secure, and is safe from prying eyes.
The communications between the user and the server is entirely encrypted, ensuring that
the footsteps are also untraceable. The connections are easy to set-up and run, making
them attractive to all internet users.

Any requests made to the server are untraceable, which makes the service very attractive
to many users. The popularity of the VPN networks has been due to this privacy feature.
