Full Description

Transmitting information across the Internet is by its nature an insecure method of transmitting data. Virtual Private Network (VPN) technology uses encryption and tunneling to permit organizations to establish secure, end-to-end, connections over third-party networks, such as the Internet. A VPN provides a portion of a security infrastructure while preserving the convenience and flexibility of off campus access. The VPN helps preserve data confidentiality and data integrity.

Vanderbilt will recommend and encourage the use of a VPN located at its network perimeter to enhance secure off campus communication and promote more restrictive access to VU servers. A VPN does not replace, but enhances, security measures that should be found at the operating system, application level and at the department level.
 
There are two parts to a VPN solution: the VPN concentrator and the VPN client software.
The VPN concentrator is a hardware device located on the Vanderbilt campus. The VPN client is software that is installed on the computer that you will use off campus. The client works with the VPN concentrator to create a secure connection, commonly referred to as a tunnel, between your computer and the concentrator.
For example, to use a remote PC, you connect to the Internet, then start the VPN client and establish a secure connection through the Internet to the campus network. When you access any application, the VPN concentrator uses a strong encryption algorithm to encrypt the data and transmits it through the tunnel to your VPN client. The VPN client software decrypts the information so you can read it on your remote PC. If you update the data , the VPN client encrypts and returns the data to the network through the VPN concentrator.

Definition
A VPN uses encryption and tunneling to permit organizations to establish secure, end-to-end, connections over third-party networks, such as:
- POTS (Plain Old Telephone Service): uses a dial-up modem to connect to your ISP
- ISDN (Integrated Services Digital Network): may use a dial-up modem to connect to your ISP
- Cable: uses a cable modem; always connected
- DSL (Digital Subscriber Line): uses a DSL modem; always connected
- the Internet.
One message that should be understood by all participants is that this VPN platform that is located at the network perimeter will terminate the encryption tunnel there, should a department have a need to extend an encryption tunnel closer to their servers they may need to fund their own VPN platform.
