What is NAC?

Network Access Control (NAC) is a computer networking solution that manages access when your computer connects to the campus network. As your computer connects, it may not be permitted to access the campus network unless it complies with NAC requirements; including anti-virus protection, automatic system updates and supported operating system. While your computer is being checked by the NAC agent (ClearPass OnGuard) it can only access resources that can remediate (resolve or update) any issues. Once the NAC requirements are met, your computer will be able to access the campus network and the Internet.

Goals of NAC

The main benefit of implementing NAC is to prevent potentially compromised computers (those that that lack antivirus, patches, or host intrusion prevention software) from accessing the campus network and placing other computers at risk of cross-contamination by computer worms or viruses that can permanently harm your computer and other computers across the network.

NAC Software

The university is using ClearPass OnGuard to check computers attempting to connect to the campus network for compliance with NAC requirements. For information on installing and running ClearPass OnGuard on your computer, please refer to the online tutorials.
