The usual suspects
One morning Wilma, the print shop manager at a beer distributor, discovers that her computer has a virus. It’s no big deal — sometimes bad things happen to good computers — so she cleans up the system and gets on with her day.
But a few days later the system is infected again.
Considerably more annoyed this time, she contacts Betty (the company’s sole IT person) to get some assistance and make sure the system is 100% clean. After disinfecting the system, Betty checks the browser history and finds that someone has been making late-night visits to X-rated websites.
The question then becomes, Who is using company resources to watch porn? At most companies, suspicion would immediately fall on the nighttime cleaning crew. But the print shop is located in the warehouse, to which the cleaning crew doesn’t have access.
