SYSTEM AND METHOD FOR CONTROLLING DEVICE-TO-DEVICE ACCESSES WITHIN A COMPUTER SYSTEM

摘要

An apparatus and a method for providing access security for a subject device (414A-D). The apparatus includes a security check unit (416, 418) configured to be coupled to a transmission medium (408, 412). The security check unit (416, 418) is configured to monitor signals on the transmission medium (408, 412) and to detect an attempt by a first device (414A-D) coupled to the transmission medium (408, 412) to access a second device (414A-D) coupled to the transmission medium (408, 412) based upon the signals. The security check unit (416, 418) is also configured to determine an identity of the first device (414A-D) based upon the signals and to control access to the second device (414A-D) by the first device (414A-D) dependent upon the identity of the first device (414A-D).
