摘要: 本发明基于OCSVM算法提出了工业控制系统通信行为的异常检测方法。该发明构建工业控制系统通信行为的正常行为轮廓模型和异常行为轮廓模型,即双轮廓模型,并通过微粒子群算法(PSO)进行参数优化,获得最优的入侵检测模型,识别出异常的Modbus?TCP通信流量。该发明通过双轮廓检测模型的协同判别以降低误报率,提高了异常检测的效率及其可靠性,更适用于实际应用。
英文摘要: The invention relates to a Modbus TCP communication behavior abnormity detection method based on an OCSVM double-contour model. The method comprises steps that a normal behavior contour model and an abnormal behavior contour model of communication behaviors of an industrial control system are constructed, namely a double-contour model, parameter optimization is carried out through a particle swarm optimization algorithm (PSO), an optimal invasion detection model is acquired, and the abnormal Modbus TCP communication flow is identified. Through the method, the false alarm rate is reduced through cooperation discrimination of the double-contour detection model, efficiency and reliability of detection on abnormity are improved, and the method is more suitable for practical application.
