The invention provides a network attack detection method, system and device and a medium, and the method comprises the steps: obtaining a plurality of continuous network flow data in a to-be-detected network, and extracting a plurality of flow features in each piece of network flow data; performing data standardization conversion on all the flow characteristics to obtain a plurality of characteristic values in the same numerical range after conversion; taking each characteristic value under each network flow data as a numerical value of each channel in pixel points of multiple channels in sequence to obtain a plurality of pixel points, and splicing each pixel point corresponding to a plurality of continuous network flow data in sequence to obtain a flow characteristic image of the to-be-detected network; and inputting the traffic feature image into a pre-trained attack stage classification model to obtain an attack stage classification result, and determining a target attack stage of the network attack behavi
