Network Access Control (NAC)

Network Access Control

NAC Information

TCNJ employs a Network Access Control or NAC device to help prevent a computer from becoming a victim of virus, spyware, spam, or trojans, and also from spreading such malware.  The NAC also replaces the IT registration database and the Resnet registration application with an electronic equivalent that associates a TCNJ community member with a computer.

The NAC works by electronically enforcing the Computing Access Agreement and Resnet Access standards.  These security requirements are available at the following websites:

http://it.pages.tcnj.edu/security/network-access-control-nac/computer-access-agreement/

http://www.tcnj.edu/~resnet/documentation.php

 

A summary of the College’s security requirements is:

  • use appropriate and up-to-date anti-virus software
  • keep your computer up-to-date with operating system patches
  • do not use peer to peer file sharing applications
  • do not disrupt the work of others

 

Anti-virus software is available from TCNJ free of charge here:  http://www.tcnj.edu/~resnet/software.php

Allowed antiv-virus software vendors include Avast!, AVG, Authentium, AVGuard, BitDefender, EZ AntiVirus, Kaspersky, McAfee, Microsoft OneCare, NOD32, Panda, Sophos, Spysweeper AV, Symantec, TrendMicro, and ZoneAlarm.

The information collected by the NAC includes your username, IP address, MAC address, and security profile of your machine gathered from the state of your anti-virus software, operating system update settings, and any peer to peer file sharing applications.  This information resides on a TCNJ server and is not transmitted off campus.


Fall semester 2011

Labs and Faculty/Staff (Wired Computers) – The SafeConnect Policy Key client should be preinstalled on your TCNJ-owned computer.  Provided that the SafeConnect Policy Key client is installed:

– When you login to the network your credentials are automatically passed along to the NAC so you will not see a second login prompt for the NAC

– Your TCNJ-owned computer receives anti-malware and operating system updates automatically so it will never be blocked from accessing network or Internet based resources

If you bring your personally-owned computer to campus you will be prompted to install the SafeConnect Policy Key client and comply with the College’s security requirements (listed above).

Wireless (Campus Wide) – Your computer will be blocked from accessing the Internet if it does not comply with the security standards of the College.
