At times it becomes necessary to isolate a computer from the campus network in order to protect the integrity of the network and/or the institution. One situation where this becomes necessary arises from use of a computer to conduct illegal activities or activities that violate university policy; another arises from a computer generating network traffic that adversely impacts the performance of the network. Network quarantine is the mechanism employed by ITS to isolate offending computers from the campus network until these kinds of problems can be rectified.
