Abstract:

Software Defined Networking (SDN), an emerging networking paradigm, has introduced more severe Distributed Denial of Service attacks (DDoS) along with convenience. Existing works typically use machine learning models to detect DDoS attacks, but ignore the additional overhead that models impose on SDN controllers. In order to detect DDoS attacks more efficiently and accurately, this paper adoptd a strategy of multi-level detection modules: the first-level module detectd suspicious traffic by calculating the joint entropy of the traffic in the current window; the second-level module used a semi- supervised model that used techniques such as feature selection, multi-training algorithms, and multiple clustering to improve detection performance by training multiple local models. Compared with other existing models, this model performs best on multiple data sets and has better detection accuracy and generalization ability.
