Why am I getting quarantined on the campus wired network?

If your computer is being quarantined by **Cisco Identity Services Engine (ISE)**, it generally means that the device has failed to meet certain network security policies or compliance checks defined by the ISE system.

  1. Outdated or Missing Software
    1. Your computer might lack the required security updates, antivirus software, etc.
  2. Non-compliance with Network Policies
    1. If your system does not comply with certain requirements like encryption, certificate installation, or login credentials, it may be quarantined.
  3. Infected or Compromised System
    1. If ISE detects malware, abnormal behavior, or suspicious network traffic from your machine, it may be quarantined.
  4. Unauthorized Device
    1. If your device is not recognized or authenticated correctly (e.g., wrong credentials or missing certificates), it may be quarantined.

What to do if your computer gets quarantined?

  1. Unplug and reconnect your network cable, then restart your device. If that doesnt work try step 2:
  2. Unplug the Ethernet cable, then connect to Eduroam
    1. Once connected to Eduroam, power cycle computer (hold power button until machine powers off) 
    2. Power the device back on and connect Ethernet and login.  
  3. If you are still having issues, please contact the OneIT Service Desk at 704-687-5500 or submit a ticket.
