California law requires individual notification where the security of personally-identifiable or other confidential information has been compromised.
If you suspect that a computer or system for which you are responsible has been compromised:
If the system contains Level 1 or Level 2  data, this is an information security emergency. Telephone the Campus Information Security Office (ISO) at (707) 826-3815 immediately, or ask your supervisor to send an email to firstname.lastname@example.org .
Make no public statements about the incident. All questions must be referred to the ISO during any investigation. After the investigation, specific referral directions will be issued by the ISO.
For after-hours emergencies, please email email@example.com  or call UPD at (707) 826-5555.
