Abnormal flow detection method and device, readable storage medium and electronic equipment

The embodiment of the invention provides an abnormal flow detection method and device, a readable storage medium and electronic equipment. The method comprises the following steps: classifying a received second flow segment into two groups of flow, namelya first flow group and a second flow group, by adopting a first classification model, wherein the first classification model is obtained by calculating a received first flow section by adopting a single classification algorithm, the first flow section and the second flow section are adjacently received flow sections, and the first flow section is received before the second flow section; extracting abnormal flow features from the first flow group and the second flow group, and if the abnormal flow features are extracted, adding the abnormal flow features into an abnormal flow feature set; and according to the abnormal flow feature set, detecting whether the received flow is abnormal flow, and if the received flow is abnormal flow, discarding the flow.
