Abstract:

To solve the problems of low classification accuracy and insufficient feature extraction of small samples in existing intrusion traffic detection models, an improved residual network algorithm based on adaptive synthetic (ADASYN) sampling and Inception-Resnet modules is proposed. The algorithm can optimize the unbalanced data set and improve the feature extraction ability of small sample effectively. Firstly, the unbalanced data training set is oversampled to improve the data distribution, and then the non-data part is processed and integrated with the data part to reduce the complexity of pretreatment. Finally, the improved residual network model is used to train the data, and the performance evaluation and algorithm efficiency comparison are carried out. The experimental results show that the detection accuracy of intrusion traffic by the improved residual network model reaches 89.40% and 91.88% respectively in the case of multi-classification and binary classification. Compared with the classical deep learning algorithm, the improved residual network model has higher accuracy and lower false alarm rate, which has higher reliability and engineering application value.
