Network data detection method and device, electronic equipment and storage medium

The invention provides a network data detection method and apparatus, an electronic device and a storage medium. The method comprises the steps of obtaining to-be-detected network data; based on the threat detection model, detecting the to-be-detected network data to obtain a detection result, the detection result being used for representing a threat condition of a network behavior corresponding to the to-be-detected network data to the network system; the threat detection model is obtained by training based on a target data sample set, the target data sample set is obtained by oversampling historical network data of a network system based on an attention mechanism, and the number of positive samples in the target data sample set is equal to the number of negative samples. According to the embodiment of the invention, the historical network data is oversampled through the attention mechanism, redundant data in the oversampling process can be reduced, data loss can be avoided, the threat detection model can be
