VPN (Virtual Private Network) is a way to create a network is "private" and secure by using public networks such as the Internet. Basically a VPN is built on two principles, as the name of the virtual and private. The term virtual means the absence of actual physical representation of the two sites link to it. This means not a dedicated link between the two locations are diinterkoneksi, so no need to draw a special cable between the two locations. Connection is done by using existing networks are also used by many other users.
VPN can send data between two computers over a public network so as if connected by point to point. Data encapsulated (wrapped) with a header that contains routing information for a point-to-point connection so that data can pass through the public network and can reach the end goal.
The term private means that the assurance of confidentiality in the interconnect of the data or information submitted .. As information-important inforrmasi not want to be read by other users who have no right, so that should be created a mechanism to keep the information remains limited. The way to achieve this is to use encryption, so that only trusted parties only, who can access the information.
