Abstract:

The acquisition of network traffic data is relatively easy, while marking the traffic data is comparatively challenging. Semi-supervised learning utilizes a small amount of labeled data and a large amount of unlabeled data for training, reducing the demand for labeled data and effectively adapting to anomaly detection in massive network traffic data. This paper conducted an in-depth investigation into the field of semi-supervised network anomaly detection in recent years. Firstly, it introduced some basic concepts and thoroughly analyzes the necessity of using semi-supervised learning strategies in network anomaly detection. Then, from the perspectives of semi-supervised machine learning, semi-supervised deep learning, and the combination of semi-supervised learning with other paradigms, it analyzed and compared the recent literature on semi-supervised network anomaly detection and summarized the findings. Finally, the current status and future prospects of the field of semi-supervised network anomaly detection were analyzed.
