The School of Medicine deployed the Network Access Control (NAC) agent to most computers in the School earlier this year. The NAC agent is helping to secure our network against viruses and malware by forcing machines attached to our network to remain current with the latest Windows security patches, antivirus, and other software patches. In the near future, machines that do not have the NAC agent installed will be blocked from the network. If you do not have the NAC agent installed, please install it now. The software is available from the UNC shareware site (https://shareware.unc.edu/#n). To see if it has been installed on your machine, look for an icon in your task menu (lower right corner of your screen) that is a red circle with a white e.
Java exploits are the number one cause of virus and malware on desktop computers. Next week, the NAC agents will begin pushing out alerts to machines that have old versions of Java installed. Those machines will first receive instructions on how to uninstall the older versions of Java. If, after two weeks, the older Java has not been removed, the machine will be blocked from the network until the older version of Java has been removed.
