Research on malicious traffic detection based on image recognition

With the rapid development of the internet, information security problems caused by malicious traffic are becoming more and more serious. Malicious traffic invades the target system, interferes with the regular operation of the target internet device, steals user privacy, and destroys network availability. Therefore, this paper proposes a malicious traffic detection method based on image recognition technology, which is used to detect network traffic data, mine malicious traffic, provide early warning for users, and avoid network security threats. Based on the feature extraction of the text information of the network traffic data, the method converts the string data of the network traffic into picture data containing feature information, and combines the convolutional neural network (CNN) to realise the analysis of the attack vector detection on network traffic. Experimental results show that, compared with traditional machine learning methods, this method has a more efficient and accurate identification ability for malicious traffic attacks.
