Abstract
A system and method are disclosed for preventing detection of a computer connection to an external device. The external device is connected to the computer via a connectionless port. A key to be used to generate valid authorization information to be included in all valid data packets sent between the computer and the external device is provided. The external device is configured to reply to any packet in which the required valid authorization information is not present with the packet that would be sent if the connectionless port were not in use.
