Frequently Asked Questions
What is Virtual Private Network (VPN)?
Virtual Private Network (VPN) is a secure way for connecting and transmitting data using an existing internet connection. VPN technology provides security for data-in-transit by utilizing encryption and authentication. Two common types of VPN are remote access VPN and LAN-to-LAN VPN.
Remote access VPN is used for connecting an employee or vendor to a corporate network using an internet connection and a VPN client. This is also known as client to server VPN. The connection can be established from any computer which has an internet connection.
LAN-to-LAN VPN is used for connecting two corporate networks. This is also known as site-to-site or business-to-business VPN.
Why should I use remote access VPN?
The VPN client software encrypts the data stream so that only the VPN server can understand it. This provides a method for secure communication. Its use also allows a computer to appear to be connected directly into the UC Davis Health network, even though the user is actually connecting via a client through an Internet Service Provider (ISP). The common uses for remote access VPN are: access to files and folders on network drives, access to intranet sites, remote administration of systems and resources, and so on.
How do I request remote access VPN?
You or an UCDH employee will need to submit an "Online Access Request Form". Instructions can be found by selecting the VPN Request Procedure link. Once you have been authorized and account setup completed, you will receive instructions on where to get the client and how to install it on your computer.
