ABSTRACT:

BACKGROUND
This disclosure relates to a computer and, more particularly, to a computer provided with a detector that detects intrusion into the interior of the computer and provides an indication of same.
It is often desirable, for security and other reasons, for the owner, or user, of a computer, to know if someone has accessed the interior of his computer. For example, in network systems including a large number of desktop computers, various components in the chassis of the computers often have to be replaced by the systems manager. In these situations, it is desirable that the user of the computer know that someone has accessed his or her computer and made the replacements.
Also, since valuable, sensitive, and secret data can be removed from the computer by physically removing the hard drive from the computer, it is important that the user also know when an intrusion of this type has taken place.
SUMMARY
Therefore, the present disclosure is directed to a computer having a detector for detecting an intrusion into the chassis of the computer.
To this end, an embodiment of the present invention features an electrical switch adapted to open when the cover of the chassis of the computer covers the chassis and close when the cover is removed from the chassis. A mechanism is provided that turns on in response to the closing of the switch for providing an output, and an indication device is connected to the mechanism and is adapted to provide a corresponding indication when the mechanism turns on.
The embodiment provides an advantage of indicating chassis intrusion in a relatively simple manner, yet prevents overriding or clearing of an intrusion event.
