Physically securing your computer, high value items, and personal belongings and property, locking your office when you will be away and keeping hand tools in a locked tool box or cabinet should be a high priority for everyone at SLAC. Know or find out who your computer administrator is to ask for additional information in securing your computers. If someone is in your area removing computers or equipment, stop and question him or her.
