Virtual Private Networking - What is it? Why Use it?

What is Virtual Private Networking (VPN)?

Virtual Private Networking (VPN) uses encryption and key exchange to provide secure communications over insecure networks. Typically, VPN is used to connect a remote computer or network back to an organization's primary network where protected resources, like your access to email or shared drives, reside. When you connect through a field office network, you're automatically connecting through a Virtual Private Network. However, you can also use VPN on an individual basis to connect to protected resources when you're not on the IASTATE network.

When should I use VPN?

Any time you need to access sensitive resources at ISU from outside the ISU network and/or on your personal computer, you should use VPN. Some resources will require VPN while others use alternate forms of security. You should always use VPN when accessing ISU resources over a wireless network.
