description The invention relates to a network security detection method and device and a computer readable storage medium, and relates to the technical field of the Internet. The method disclosed by the invention comprises the following steps of acquiring a flow value at a current sampling moment in a network; predicting the flow value of the current sampling moment by using a local weighted regression modelcorresponding to the flow value of the previous sampling moment; and comparing the acquired flow value with the predicted flow value, and determining that the risk exists in the network when a difference value between the acquired flow value and the predicted flow value exceeds a threshold value. According to the method disclosed by the invention, the flow value of the current sampling moment ispredicted each time, and the model is retrained by utilizing the flow value of the adjacent historical sampling moment, so that the local weighted regression model can be dynamically corrected in realtime, the potential risks
