What is a VPN? A simple definition of Virtual Private Network, or VPN, as it is commonly known, is the use of a public network - mainly the Internet, to create private, secure wide area networks. A more formal definition of a VPN: a combination of tunneling, encryption, authentication, and access control technologies and services used to carry traffic over the Internet, a managed IP network or a provider's backbone. The traffic reaches these backbones using any combination of access technologies, including T1, frame relay, ISDN, ATM or simple dial-up access. VPN Technologies As stated above, there's one thing all virtual private networks have in common: They all share the same core set of technologies, which consists of tunneling, encryption, authentication and access control. Tunneling. Tunneling is at the core of all VPN implementations. There are basic classes of tunnels: end-to-end tunneling and node-to- node tunneling. With end-to-end the tunnel extends from a remote user!'s PC to the server that the user is connecting to. In this type of scenario, the devices at each end of the connection must handle the establishment of tunnels, and also encrypt and then decrypt the data that's being passed between the two points.

For example, when using a VPN, companies may be able to get rid of their modem pools and remote-access servers. VPNs use the relatively free bandwidth of the Internet or a service provider's network to connect a user to a corporate network or carry traffic between sites. Typically 40-bit to 128-bit sized keys are used in commercial applications. The savings a VPN can offer increases exponentially when applyin!g it to a company with many international sites. Industry experts estimate that there were about 7. In this type of configuration, all the traffic on each LAN is unchanged. The general idea of a VPN intranet is to use the encryption, authentication and access control services of a VPN to segment populations on a corporate network or intranet. The correct key size depends on many factors.
