Residual Observability and Attack Detectability in Encrypted OPC UA Traffic
Song Son Ha, Florian Foerster, Henry Beuster +3
OPC Unified Architecture (OPC UA) encryption conceals application-layer semantics and restricts intrusion detection to residual communication structure. Although machine learning-b…
Converging Safety and Security: IO-Link Wireless and OPC UA over 5G under prEN 50742
Henry Beuster, Thomas Robert Doebbert, Gerd Scholl
The integration of wireless communication technologies in industrial automation offers greater flexibility, but also exposes safety systems to a broader threat vector. Emerging reg…
Impact of Benign Connectivity Variations on Intrusion Detection for Encrypted OPC UA Traffic in Industrial Private 5G Networks
Song Son Ha, Florian Foerster, Henry Beuster +3
Machine learning (ML)-based intrusion detection systems (IDSs) are increasingly used to monitor encrypted industrial communication. However, their behavior under realistic private…
An Experimental Study of Machine Learning-Based Intrusion Detection for OPC UA over Industrial Private 5G Networks
Song Son Ha, Kunal Singh, Florian Foerster +4
Industrial deployments increasingly rely on Open Platform Communications Unified Architecture (OPC UA) as a secure and platform-independent communication protocol, while private Fi…
Testbed and Software Architecture for Enhancing Security in Industrial Private 5G Networks
Song Son Ha, Florian Foerster, Thomas Robert Doebbert +3
In the era of Industry 4.0, the growing need for secure and efficient communication systems has driven the development of fifth-generation (5G) networks characterized by extremely…
