Reasons for Isolation

Some explanations can, but not always, be attributed to the following unless an exception has been made:

  • Devices that exhibit behavior consistent with an active infection
    • Regular and reoccuring notices implying an underlying infection that hasn't been mitigated
    • 2+ types of malware notices present simultaneously which might indicate an active and spreading infection
    • Critical notices having a severity, determined by the analyst, to warrant isolation
    • Unresponsive device owners concerning prolonged notices over 3 days from unmitigated infections
    • See also APM 30.14 Proactive UI Network Security Measures
  • Devices that have software or Operating Systems past End-of-Life (EOL) and highly susceptible to attack
    • ex: Windows 7

What Next?


  • Local Support / TSP:

    • Determine and complete the level of remediation necessary

    • Network capabilities will be restored to the device when OIT Security is notified of completed remediation
