Network & Internet Services

Clearing a web browser’s cache can correct problems you may have using a web browser while on the CU Boulder network or using an OIT web based program, like our learning management systems. OIT recommends that you perform this simple step before you start to surf the Web for the first time on the campus network.

Wireless network security is a serious issue. Wireless is not only a shared medium, but also a medium that is broadcast via radio waves which means that anyone with a wireless card could monitor your network traffic, including your passwords, account numbers, etc. Thus the data is inherently insecure.

In order to protect data sent over the wireless network, please ensure it is encrypted using SSL, SSH, or VPN.

For more information, visit the Office of Information Security website and OIT's Virtual Private Network (VPN) information.

Use of VPN encryption software is subject to United States Department of Commerce regulations.

To make internet connection resources more widely available, a few restrictions apply to all CU Boulder VPN users. These restrictions enable more people to get connected and help maintain the stability and security of the service.
