Rapid and accurate anomaly traffic detection is one of the most important research problems in cyberspace situational awareness. In order to improve the accuracy and efficiency of the detection, a two-stage anomaly detection method based on user preference features and a deep fusion model is proposed. First, a user-preference list of attack detection tasks is constructed based on the resilient distributed dataset. Following that, the detection tasks are divided into multiple stages according to the detection framework, which allows multiple worker hosts to work in parallel. Finally, a deep fusion classifier is trained using the features extracted from the input traffic data. Experimental results indicate that the proposed method achieves better detection accuracy compared to the existing typical methods. Furthermore, compared with stand-alone detection, the proposed method can effectively improve the time efficiencies of the model’s training and testing to a large extent. The ablation experiment justifies the use of the machine learning method.
