Questions & Answers
What is Network Access Control (NAC)?
Network Access Control is a system that ensures only authorized devices can connect to the wired network. NAC verifies the identity of the end user before granting access to the wired network.
Why do we have to authenticate on the wired network?
After a recent audit finding by the university, we are being tasked with remediating unauthorized access to university wired network resources. Presently, anyone could plug their device into our wired network ports and gain full network access. This would leave university systems vulnerable to access from non-affiliated users. By implementing network access control, we improve cybersecurity by excluding unauthorized users’ ability to access the network.
What is a MAC address?
A MAC (medium access control) address is a unique code given to a device’s network connection (like Wi-Fi or Ethernet) that helps identify it on a local network. It's kind of like a name tag that lets other devices know who it is when sending or receiving information.
What if I don't know my MAC address?
You will not need to know your device's MAC address. When you login for the first time the device's MAC address will automatically be registered.
How will I connect a device that does not have the capability for interactive (web) authentication? (IOT, Printers, TVs, etc.)
As this change is rolled out, IT administrators will be given access to register the MAC addresses for devices that can’t do interactive (web) authentication (printers, SCADA, laboratory equipment, cameras, computer labs, etc.).
Will devices that are currently connected still need to be registered?
Yes, everything will need to be authenticated.
What happens if there are MAC address conflicts?
There should never be a MAC address conflict since these addresses are individually encoded to each specific device.
Is there a limit on how many devices a user can register?
No, there will not be a limit.
Will NAC slow down my connection?
No, once your device is authenticated to the network, there is no performance impact
Will this affect wireless connectivity?
No, this will not affect wireless connectivity
Will I be able to connect to the wired network if I am not an active student or employee?
No, you will not have the ability to connect to the wired network. If you need internet connectivity, you may use OSUGUEST Wi-Fi. If you need a wired connection, please contact the IT department of the college you are working with
How often will I have to authenticate?
You will have to authenticate the device once every 130 days. This time frame is subject to change
Will I have to re-authenticate if I move to a different building?
No, you will not have to re-authenticate. Once your device is authenticated, you will be able to connect to the wired network in any building.
What if I'm using a USB Ethernet Adapter or docking station?
MAC address authorization is tied to the NIC MAC address.
If you:
- Change USB Adapters
- Switch docking stations
- Replace your device's network card
You may be prompted to authenticate again.
I get a certificate error when I connect to the wired network on a Mac
Unfortunately, this is expected behavior if the default browser of the Mac device is Safari. Safari does not register that this is a cpative portal redirection and will stop the connection. To proceed, you may accept the certificate, or you may try connecting to the network via different browser(i.e. Chrome, Firefox).
