1. A transmission device for transmitting data between a first network and a second network, the transmission device comprising:
a first unidirectional transmission unit, which is couplable to the first network and designed to exclusively receive data transmitted from the first network to the transmission device;
a second unidirectional transmission unit, which is couplable to the second network and designed to exclusively send data from the transmission device to the second network;
a detection unit, which is arranged between the first unidirectional transmission unit and the second unidirectional transmission unit and designed to receive the data received by the first unidirectional transmission unit and to detect anomalies in the received data; and
a modeling unit arranged between the first unidirectional transmission unit and the second unidirectional transmission unit, wherein the modeling unit is designed to provide a model on a basis of preconfiguration data comprising a specific network topology of subscribers in the first network, and wherein the modeling unit is designed to make the model available to the detection unit so that the received data could be analyzed by the detection unit,
wherein a unidirectional communication connection in the transmission device exists exclusively from the first network to the second network and communication in the transmission device from the second network to the first network cannot occur.
