Die Komponenten in modernen Produktionsanlagen werden immer mehr vernetzt. Mit erhöhter Flexibilität und Rekonfigurierbarkeit steigt aber auch die Gefahr von Cyber-Angriffen. Um die Produktionsanalagen besser vor Cyber-Angriffen zu schützen, werden neuartige auf Systemtheorie basierte Algorithmen zur frühzeitigen Detektion von Cyber-Angriffen entwickelt. Darüber hinaus wird untersucht, wie der Einfluss der Cyber-Angriffe auf das Systemverhalten unterdrückt werden kann.
