VPN stands for Virtual Private Network. VPN is a private network which is constructed within a public network infrastructure (such as global internet). In this private network, access is controlled to permit peer connections only within a defined field of interest and is constructed. A VPN network creates a secure connection over a public network i.e. the internet being one of the most important requirements of daily lives. The Encryption for such a connection is provided by using algorithms for having security and the establishment of a reliable connection which is not possible in the case of a proxy server. There are several different types of Virtual Private Networks. These VPN’s are available depending on the functional requirements and several different methods of constructing them. While selecting a VPN the problem which is to be solved should be considered and risk analysis should be done for that particular implementation.
