Abstract
A database unit monitors the communications occurring within at least one communication system for hardware identification codes of communication or broadcast units. Upon detecting the hardware identification code, the database unit compares the one received with a stored hardware identification code for the unit. When the stored hardware code does not match the one received, the database unit indicates that the unit has undergone an unauthorized modification.
