Network Access Control (NAC)

Beginning January 2012, ITS will implement a Network Access Control (NAC) system across all the campus wired/wireless networks. 


The purpose of a NAC system is to prevent compromise of the computers that connect to the network or other network resources. When a computer infected with a virus connects to the SSU network, it can infect other connected computers or even damage infrastructure such as servers and network gear. The best mitigation against this risk is to ensure that any computer seeking connection to the SSU network has effective Antivirus (AV). A Network Access Control system enables IT departments to deny network access to unprotected computers and to guide the user to links where appropriate Antivirus can be downloaded.


This is how it works. The NAC checks each computer as it connects to be sure AV is installed, running and that it is a current version. If not, the user is automatically quarantined. To be removed from quarantine, the user must either enable/update their existing Antivirus or download/install a new one. Links are provided to both free and fee-based AV’s. Even though the computer has been quarantined, our NAC allows access to AV vendors’ web sites.


Since the beginning of the Fall 2011 semester, the ImpulsePoint NAC system has been successfully deployed for all SSU students and guests on the wireless network, and all wired users in the residence halls.
