Technique for remote administration of a device by an administration server

A technique for remote administration of a device to be administered. A relay device receives a request to activate a filter for administration of the device to be administered from a referring administration server. This activation request includes information relating to rights assigned to a third-party administration server for delegating the administration of the device to be administered. The relay device then applies a filter to a message received from the third-party administration server intended for the device to be administered, the message received from the third-party administration server being filtered by the filter when it does not comply with the rights assigned to the third-party administration server.
