Abstract
A method for detecting hidden malicious traffic based on a traffic interaction map and a device are provided. The method includes monitoring traffic passing through a gateway by a detection system operating in the gateway; obtaining a data packet granularity feature by performing feature extraction of granularity of a data packet on the traffic monitored; constructing a traffic interaction map according to the data packet granularity feature to represent a long-term interaction mode of the traffic by a graph structure of the traffic interaction map; and detecting an abnormal local structure on the traffic interaction map by a detection algorithm of graph learning based on the traffic interaction map, and marking the abnormal local structure as the corresponding hidden malicious traffic.
