Network Access Control (NAC)

To provide a more stable and secure network, DU employs a Network Access Control (NAC) system to assure that devices connected to the network meet these minimum security requirements:
  • Each desktop computer or other listed device must be authenticated using your DU ID and password.
    Guests: if you do not have a DU ID and wish to access the campus network please contact the department (or responsible party) that you are visiting or are associated with and ask them to complete the DU Network Guest Form.
  • In addition systems running Microsoft Windows:

The Policy Key

To ensure compliance with these requirements, when first connecting an affected device to a wired connection at DU, one with an ethernet cable between the computer and the wall port, users will be required to authenticate and to download and install a software Policy Key. The Policy Key automates the required policy checks.

The Policy Key is only active on your computer when it is plugged into a wired port at DU. It will not interfere with wired connections when using your computer off campus. For example, you will be able to use your computer on a wired connection at DU, unplug it, take your computer to an off campus wired network and use it as you would have before the Policy Key was installed.

Installing the Policy Key

The first time a device is connected to the DU wired network and a browser is opened, you will be prompted to enter your DU ID and Password.

Before being allowed to access the University network and the Internet, you must enter your credentials to authenticate. Once you are successful you will be guided through the steps to download and install the Policy Key.

For detailed information on the Policy Key install process please see:
