Cyber Incidents

Responding to a Cyber Incident

Cyber incidents are becoming increasingly common.

If the cyber incident includes a threat to life or property – call 911.

  • If you believe your system is or has been attacked, look for signs of suspicious activity or anomalies on your system or network traffic.
  • If you suspect your system is compromised, remove its access to the internet immediately and turn it off.
  • Notify the University’s Information Security Team by making a report through the Security Matters website
  • If you suspect any criminal activity, report the matter to Campus Safety.


Cyber attacks are critical and complex processes that require swift action to mitigate damage and prevent further compromise.

Cyber incidents can affect the security and privacy of the University’s network.
