Abstract:

In order to solve the problems of low prediction accuracy and slow convergence speed of existing network security situation prediction models, a prediction method based on temporal convolution network (TCN) and bi-directional long short-term memory (BiLSTM) network is proposed. This method firstly applies the advantages of TCN in dealing with time series problems to the sequence characteristics of learning potential values in situation prediction, then introduces the attention mechanism to dynamically adjust the weights of attributes. Secondly, the proposed method uses the status before and after learning potential values of BiLSTM model to extract more information from the series for prediction. Particle swarm optimization(PSO) algorithm is used to optimize the hyperparameters to improve the prediction ability. The experimental results show that the fitting degree of the proposed prediction method can reach 0.999 5, and its fitting effect and convergence speed are better than other models.

Key words: network security, situation prediction, temporal convolution network (TCN), bi-directional long short-term memory network (BiLSTM), particle swarm optimization (PSO), attention mechanism
