Abstract: A data collection network is disclosed. The network includes a plurality of devices and a collection apparatus suitable for collecting data generated by the devices. The network further includes a plurality of data-diode-type equipment items respectively associated with the devices, each device being connected to the collection apparatus via the associated data-diode-type equipment item. Each data-diode-type equipment item is arranged to render unidirectional the connection between the associated device and the collection apparatus, in the direction from the device towards the collection apparatus. Such a network thus makes it possible, in the event of an intrusion into one of the devices or into the collection apparatus, to prevent the intrusion from spreading to other devices.
