Wireless is a shared medium that is broadcast via radio waves. This means that data transmitted by wireless users can be easily captured, making sensitive information (such as social security numbers and credit cards) transmitted wirelessly inherently insecure.
It's important that you take additional steps to encrypt and protect sensitive information that you send over a wireless network. And that means anywhere you connect wirelessly; like in the UMC, at Starbucks, at DIA or even home wireless networks. One way to protect yourself is to use the campus's VPN (Virtual Private Network). A VPN provides a secure encrypted tunnel from your computer to CU's network whether you are on or off campus.
VPN software is available, at no cost, for download from OIT for Windows, Mac and even Linux and Solaris machines.
