1. A communication module for data transmission between at least one hardware component which is integrated into an internal network of a technical system and a back-end computer system which is connected to a packet-switched data network, characterized in that the communication module comprises:
a point-to-point connection, wherein communication is carried out via the point-to-point connection according to a non-routable protocol that prevents rerouting of communication and precludes unauthorized access to the internal network,
a device-proximal gateway is configured and arranged to provide a data transmission interface between the point-to-point connection and the internal network, and
a network-proximal gateway connected to the device-proximal gateway via the point-to-point connection without intermediate stations, the network-proximal gateway configured and arranged to provide a data transmission interface between the packet-switched data network and the point-to-point connection, wherein the point-to-point connection is the only connection between the network-proximal gateway and the device-proximal gateway, and wherein the network-proximal gateway is directly connected to the packet-switched data network without intermediate stations.
