If you are using the wireless network on campus, you might want to encrypt your data. Otherwise, anyone with a wireless laptop can monitor your data between your laptop and the wireless access point (WAP).

Typically we have users set up the Library proxy server for this purpose, but this doesn't work for everyone. For these people, the VPN? is the only other option. Finally, many ISPs have started blocking ports which certain applications (such as Outlook) need to work correctly. If your ISP is blocking ports, you will want to use VPN.
