Don't think for one minute your old security guard is a non techie person. He could probably hack his way into your system while you are sleeping. Breaches do occur from inside a firewall probably more frequently than from out in the internet.
A former security guard at a General Motors Corp.'s technical center has been charged with stealing documents containing the names and Social Security numbers of about 100 GM employees and using those numbers to hack into the company's employee-vehicle database, county police said. The ex-employee, James S. Green, of Washington Township, Mich., then sent e-mails to those employees asking them questions about their vehicles.
