摘要:

As the core of moving target defense, defense strategy has been the focus of research. However, the existing defense strategies of moving targets defense lack pertinence and still belong to the real-time and passive defense state. In order to realize the advance deployment of defense measures, network traffic should be accurately predicted in the long-term. In this paper, a traffic prediction model based on segment lifting wavelet transform and LSTM network is proposed (LSTM-SLWT). Furthermore, the distance between the reconstructed traffic and the predicted approximate sequence is calculated by using the dynamic time warping algorithm, and the distance is considered as the possible DDoS attack intensity. Then the genetic algorithm is used to select the mutation element variation range that can carry out effective defense. So as to verify the effectiveness of the proposed method, this paper conducted a prediction experiment on the traffic of different time lengths. Experimental results show that the prediction effect of LSTM-SLWT is better than that of LSTM and the traditional LSTM-LWT prediction model. Moreover, the effective defense strategy is selected on the basis of traffic prediction, which can reduce the defense cost while ensuring the security of the system. © 2022 IEEE.
