Abstract

A threat detection method includes: obtaining packets in a Transmission Control Protocol (TCP) session between a first device and a second device; obtaining a first data flow transmitted from the first device and a second data flow transmitted from the second device in the TCP session; obtaining time information of each of a plurality of first packets in the first data flow and time information of each of a plurality of second packets in the second data flow; calculating an activation rate, a response rate, and a quantity of interactions based on the time information; and if the activation rate is greater than or equal to a first threshold, the response rate is greater than or equal to a second threshold, and the quantity of interactions is greater than or equal to a third threshold, determining that the first device is threatened.
