Cisco NAC FAQ

 

Q: What is Cisco NAC?

A: Cisco NAC is a solution provided by Cisco, Inc. that performs network validation. The software performs the following functions:

  • Requires authentication to the NIU Network
  • Validates whether the system connecting to the network meets the minimum security requirements.
  • Temporarily quarantines the system until it meets the minimum security standards.
  • Provides temporary access to NIU websites and the Windows Update services
  • Once the system meets the requirements, it will allow access to the NIU Network

Q: Why Cisco NAC?

A: Student machines are introduced to the campus that potentially contain harmful viruses and malware. On move-in weekend in particular, worms and viruses attempt to spread to unpatched/vulnerable machines. ResTech and ITS determined that the best way to prevent this from happening is to insure that virus software and Operating System critical update/patches are current and maintained.

Q: Can I use my XBOX, Nintendo, and/or Playstation?

A: Yes! These devices are automatically allowed to join the NIU Network without going through Cisco NAC. Nintendo DS and Sony PSP units cannot access the wireless in the residence halls, but look for updates released by their manufacturers as they continue to improve their products and make them compatible with more systems.
