Abstract
A traffic anomaly sensing systemincludes a preprocessing unit, a local graph feature generation unit, a global graph feature generation unit, a learning unit, and an anomaly determination unit. The preprocessing unitgenerates a communication history graph from traffic data. The local graph feature generation unitgenerates, from the communication history graph, a local graph feature about a certain vertex. The global graph feature generation unitgenerates, from the communication history graph, a global graph feature about a vertex. The learning unitgenerates a feature vector by combining the generated local graph feature and the generated global graph feature and generates a learned model for each host identifier. The anomaly determination unitdetermines whether the traffic data is anomalous or not by inputting the graph feature to the generated learned model.
