ABSTRACT:
A method, apparatus, and computer program product for controlling access to a target device utilizes an initiator identifier to either permit or deny access to a selected portion of the target device. To that end, a message having the initiator identifier is directed from the initiator device to the target device to request access to the selected portion of the target device. Upon receipt by the target device, it is determined if the initiator identifier is in a permitted set of identifiers associated with the selected portion of the target device. If the initiator identifier is in the permitted set, then access to the portion of the target device is permitted and the initiator can access the target in accordance with conventionally known processes.
