NETWORK ANOMALY DATA DETECTION METHOD AND DEVICE AS WELL AS COMPUTER EQUIPMENT AND STORAGE MEDIUM

摘要

A network abnormal data detection method, comprising: receiving access request data sent by a client; searching the access request data for historical access request data corresponding to a user session identifier; obtaining a packet header string of the access request data; performing word segmentation on the packet header string according to a preset step size to obtain a word segmentation set; obtaining a word segmentation weight matrix according to the historical access request data and the word segmentation set; inputting the segmentation weight matrix into an abnormal data detection model to obtain a data abnormal probability; and determining whether there is abnormal data in the packet header string according to the data abnormal probability.
