The embodiment of the invention relates to an OPC UA-based anomaly detection and recovery system and method. The present invention relates to an anomaly detection and recovery system (ADRS) for an OPC UA based industrial automation network comprising an OPC UA device. The ADRS includes an anomaly detector configured to monitor an OPC UA traffic flow, the OPC UA traffic flow including OPC UA messages of the OPC UA devices, and the anomaly detector configured to analyze the OPC UA traffic flow for anomaly detection using OPC UA semantics of the industrial automation network. 本公开的各实施例涉及基于OPC UA的异常检测和恢复系统以及方法。本发明涉及一种异常检测和恢复系统(ADRS)，用于包括OPC UA设备的基于OPC UA的工业自动化网络。ADRS包括异常检测器，异常检测器被配置为监控OPC UA业务流，OPC UA业务流包括OPC UA设备的OPC UA消息，并且异常检测器被配置为使用工业自动化网络的OPC UA语义来分析OPC UA业务流以进行异常检测。
