NAC is network access control, and it is used to mitigate risks inherent in improperly protected computers. It also provides a mechanism of login, which is necessary to comply with regulatory requirements.
Taking advantage of unpatched computers is one of the most commonly used methods for spreading malware. This presents a risk not only to the individual computer user, but to others through the network. Using tools to help identify these issues is another step in minimizing these risks.
Generally yes. All Microsoft Windows PCs (2000, XP, Vista and 7) and Macintosh OS X (10.4, 10.5 and 10.6) are required to use the policy key in order to maintain network access.

On Windows, you can right-click any blank space on the task bar at the bottom of your screen and select the option "Task Manager." When the Windows Task Manager appears, click the "Processes" tab, then "Show Processes from All Users" and look for the process "SCClient.exe" and "scManager.sys."
On Macintosh machines, open the Activity Monitor, click "Show All Processes" and look for "SafeConnect" and "scManagerD."
The policy key continuously validates that your system has the minimum security software running and up-to-date. It will provide occasional warnings when certain conditions occur, such as antivirus definitions becoming outdated or Windows update or AV protection being disabled.
NOTE: As a rule of thumb, only install a single AV client, as system problems may otherwise arise.
The policy key is part of an effort to help you keep your computers free from viruses, spyware, and operating system security vulnerabilities. Machines protected in this way generally perform better and are less likely to experience downtime due to damage caused by malicious software.
Your privacy is very important to us. The policy key scans only for Windows update services compliance, anti-virus and anti-spyware status. No user data is collected or stored.
Windows Update will fail if your Windows operating system is not properly licensed. You must have a legal copy of the operating system to connect to the university network. Please contact Microsoft or your PC manufacturer with questions.
