Abstract
A network traffic anomaly detection method and apparatus is provided. The method includes: acquiring network flows generated by a network monitoring node within a set period of time; for any one of attributes in the network flows, aggregating the network flows at a set time interval according to the attribute to generate N time sequences with respect to the attribute; determining N samples to be detected corresponding to the network flows according to the N time sequence, calculating respective angular dissimilarity degrees between a first time sequence and N−1 second time sequences corresponding to a first attribute in the other N−1 samples to be detected, and determining a first detection result with respect to the first time sequence; and determining whether each of the samples to be detected is an abnormal data stream according to a detection result.
