Network attack recognition model training method and device and network attack recognition method and device

The invention provides a network attack recognition model training method and device and a network attack recognition method and device, and the method comprises the steps: obtaining a plurality of traffic packets passing through a target object and an initial network attack recognition model, and obtaining a first network attack tag of the traffic packets; for any traffic packet, generating a traffic image based on the traffic packet; inputting the traffic image into the initial network attack recognition model to output a second network attack tag; and training the initial network attack recognition model based on the first network attack tag and the second network attack tag to generate a target network attack recognition model of the target object. Therefore, the one-dimensional traffic packet is converted into the two-dimensional traffic image, and the target network attack recognition model is generated through traffic image training, so that the to-be-recognized traffic packet can be subsequently conve
