Abstract: An appliance communicates via a communication network via various communication services available for transmitting data via the communication network. The appliance can detect an anomaly in a communication that is established with the appliance via one of the communication services, and implement a defense communication mode. In the defense communication mode, the communications to be established with the appliance via a communication service for which a detection has occurred are inhibited, while the communications to be established via another communication service are allowed.

Abstract: A communication device for implementing a system for remotely managing at least one item of equipment by a management application able to communicate via a telecommunication network with an application embedded in the item of equipment. The device includes a first communication interface allowing implementation of a local communication link with the embedded application, a second communication interface allowing access to the telecommunication network, and a communication management device configured to communicate with the embedded application via the first interface and with the management application via the second interface, serving as communication relay between the embedded application and the management application, and configured to transmit to one of the two applications a message received from the other application, according to predefined transfer rules and as a function of at least one parameter received with the message.

Abstract: An apparatus and associated methodology for processing at least one data packet received by a receiving entity from a machine after transmission via at least one data transmission network. Identification data is obtained of a device involved in the transmission of said data packet. A decoding function associated with said device is identified using the identification data. The decoding function is an inverse function of an encoding function applied by the device to a packet before transmission. The received packet is decoded through the application of the decoding function.
