What is VPN?

VPN (Virtual Private Network) is a technology developed with the purpose of ensuring secure communication over the Internet and providing data transfer. The most important reason for VPN to be preferred is the cost. It is the easy and secure use of the infrastructure of an operator, as if it were a private network, for those establishments who do not own a back upped, reliable and fast network that needs high funding. This application, where general communication network systems are used, encompasses the 'tunneling protocol' system between the nodes and the security procedures of 'authentication' and 'encryption'.

The data is packed and encrypted at one end of the VPN tunnel and unpacked and decrypted at the other end and conveyed securely. Along the tunnel various protocols maintain the transfer. These are IPSec (IP Security) and SSL (Secure Sockets Layer) protocols.
