Network Access Control may change how you connect to the campus network
It's time to brush up on your Windows patches and anti-virus updates. No really. They mean it this time.
Beginning with the fall 2006 semester, your access to the UA computer network from campus residence halls and the new UA Wireless network will change as the University strives to limit network exposure to security vulnerabilities. In blunt terms, if your computer security (including PDAs) isn't up to date, you won't be allowed on parts of the campus network.
Portions of the campus network will begin to phase in Network Access Control (NAC) in August. Essentially, NAC is a way for the campus network to ensure that your Windows computer has appropriate anti-virus protection and your operating system has been updated with the latest security patches. This is necessary to protect all campus network users from rapidly spreading computer viruses and attacks due to unprotected machines on the campus network. This is no small problem.
Here's where you come in
The implementation of the NAC solution and the rollout of the new UA Wireless will require at least two significant changes in how you access the network. You may have to reconfigure your computer's wireless connection to work with the new UA Wireless, as well. (For wireless connection information, contact CCIT's Computing and Network Support, Computer Center 224, 621-4357, support.ccit.arizona.edu.)
1. Each time you make a new network connection you will be required to sign in with your UA NetID and password. This ensures that it is really you, an authorized individual who is allowed to use the campus network. Initially, only Windows users will be required to meet the NAC criteria. Mac and Linux users will only sign in with their UA NetID where required. 
2. You will be required to download a Policy Key (software on your computer) that communicates with the UA network about the security status of your system. This Policy Key does not gather personal information from your computer nor transmit that information to any third party. Your system's basic security information (patches and anti-virus) is used to determine if your machine is a risk to the campus network and NAC makes a determination whether to grant network access or to place your machine in quarantine. It is suggested, but not yet required, you have anti-spyware installed and running, as well.
If your machine is determined to be a risk to the campus network, you will be directed to a quarantined network area. There you will find links to download necessary security updates and anti-virus. Once these are installed on your computer, you will be able to access the network.

If you are having problems connecting with the NAC in the residence halls or on the UA Wireless network call OSCR at 626-TECH (8324) or visit the OSCR Underground Help Desk (ILC 136).
