Abstract: A security system for electronic devices such as computers that advantageously combines a conventional chassis assembly with an entrapment system that integrally inhibits unauthorized removal of not only the device, but also its internal components. The integrated security system preferably comprises an electronic device having a chassis and a cover attachable to the chassis, a security base plate, a first plurality of locking members attached to the base plate or the chassis, a second plurality of locking members formed in the base plate or the chassis and cover, the second plurality of locking members being adapted to receive and capture a separate one of the first plurality of locking members to secure the device to the base plate and to integrally lock the cover to the chassis while the device remains secured to the base plate, and a lock operably coupled to the device and the base plate to prevent removal of the device from the base plate.
