Mary is an Information Security Officer at a USB drive manufacturing plant. In her first week on the job, she is doing a security survey of the plant. She notices that several utility closets do not have locks. The closets house telecommunications lines and power lines for the plant. She reports this situation to her CSO. He states that if the server and sever rack rooms have locks, things are fine. Maintenance people need easy access to the utility closets. Mary doesn$$t agree and decides to write up a memo for discussion at the next plant Security Committee meeting.

Besides supplying locks for the utility closets, identify two other physical security controls that you would recommend. How would they be effective?
