Abstract

Apparatus and process are disclosed by which to disable a computer's access to all or a part of the computer's memory system or associated peripherals, so as to protect the computer from accidental or malicious damage of data files or programs that may result from the activity of computer users or computer viruses. This result is achieved by providing the authorized user with a token whereby the user can configure the security gateway to completely or partially disable the peripheral device without disrupting the operation of the computer or other peripherals. The principal hardware component of one embodiment of the invention is the security gateway which in a typical configuration simply adds new security functions to the programmable controllers that are typically used for an I/O controller or hard drive controller, although this is not always necessary. The process can just as easily be incorporated into a local network controller, a communications controller, or a main processor board for a system. The speed of the security gateway can be further enhanced by adding additional computational or encryption hardware to the chip sets used in said I/O or hard drive controllers.
