Abstract:

As the scale of computer networks and applications grows exponentially, the potential damage caused by attacks increases significantly and becomes more apparent. Traditional abnormal traffic detection methods can no longer meet the needs of Internet security, so machine learning-based algorithm has become one of the effective methods for complex and growing network attacks. This paper presents an abnormal traffic detection algorithm based on deep neural network. By comparing the current classical data sets, this paper chooses ISCX data set which contains more attack and protocol types for experimental analysis. The experimental results show that compared with naive Bayesian algorithm, the proposed algorithm greatly improves the accuracy and reduces the false alarm rate. It is an efficient algorithm for abnormal traffic detection.

Key words: abnormal traffic detection, machine learning algorithm, network attack, neural network algorithm, ISCX data set
