Abstract
For detecting a cyber-attack on a machine controller, a concurrent simulation of the machine is run in a secured access domain. From the machine controller actual control data are transmitted to the machine and resulting monitoring data are transmitted to a monitoring device. Furthermore, sensor data of the machine are transmitted to the concurrent simulation on a first secured transmission path. Based on the sensor data, the concurrent simulation simulates an operational behavior of the machine, thus inferring simulated monitoring data. The simulated monitoring data are then compared with the resulting monitoring, and an alarm signal is triggered depending on the comparison.
