• a method wherein the connections with the wired network and with the wireless network are established by sending a request from the equipment, this request comprising an identifier of the equipment, according to a predetermined connection configuration protocol,
• and wherein:
• a) connection configuration requests sent by one or more equipments are monitored, at least on the wireless network,
• b) the content of these connection configuration requests is analyzed and equipment identifiers are extracted from them,
• c) from an equipment identifier extracted in step b), it is determined if this equipment has also sent a connection configuration request at least to the wired network with the same identifier, and
• d) an alarm is raised if the result of step c) is positive.
