| 1. A system for securing remote administrative access to a processing device including a processor operative under programmed
instructions comprising:
means for receiving a series of incoming binary data packets at a designated port of an associated document processing device,
the designated port being associated with administrative control of the associated document processing device, each data packet
including source data, destination data, and a data portion for communicating administrative control data for configuration
of the document processing device;
means for receiving binary mask data defining an address space from which remotely generated requests for administrative control
of the document processing device is acceptable;
means for storing received binary mask data on a data storage local to the document processing device;
means for receiving binary reference address data representative of at least one address within an address range defined by
the address space;
means for generating a first binary value in accordance with a comparison of the binary reference address data with the binary
mask data;
means for generating a second binary value in accordance with a comparison of an incoming first binary data packet with the
binary mask data, wherein the first binary data packet is incoming at the designated port associated with the administrative
control of the associated document processing device;
determining means for determining acceptability of the incoming first binary data packet in accordance with a comparison of
the first and the second binary values associated therewith; and
means for selectively commencing, by the associated document processing device, processing of received administrative control
data of the incoming first binary data packet in accordance with an output of the determining means.
