Persons who suspect a security incident should contact the 绿帽换妻 IT Service Desk in one of the following ways:

• Call 510-885-HELP (contact by email if there is no answer)
• Visit the IT Faculty & Staff lounge at the main entrance to IT, in the south wing of the Library Annex building.

Please inform the IT Service Desk of the nature of data stored and accessed on any system suspected of being compromised, to the extent that this can be done without using or accessing the system itself.
