How often will my system be scanned by the PolicyKey?

The PolicyKey [1] continually scans your system to ensure that you meet the security requirements [2]. 

At the beginning of each term, you will need to log on to the wireless network. If the PolicyKey is still active on your machine, you will not be required to install the software again.  

If you haven't been connected to the wireless network for 60 days or more, you will be required to re-install the PolicyKey Software.

Repeat scanning and additional security measures may be initiated if a widespread security threat or vulnerability occurs.
