ABSTRACT:
A database unit monitors the communications occurring within at least one communication system for a change status indicator of communication or broadcast units. Upon receiving the change status indicator, the database unit compares the one received with a stored change status indicator for the unit. When the stored change status indicator does not match the one received, the database unit indicates that the unit has undergone an unauthorized modification.
