Within the research work, different self-learning frameworks to analyze passively captured network traces from PROFINET-based industrial system for protocol-based and process behavior-based anomaly detection are developed, and evaluated on a real-world industrial system.enIndustrielles SteuerungssystemNetzwerksicherheitNetzwerk-Intrusion-Detection-SystemAnomalieerkennungselbstlernendIndustrial Control SystemNetwork SecurityNetwork Intrusion Detection SystemAnomaly Detectionself-learningdoctoral thesis
