Abstract

The invention relates to an attack detection method and device, computer equipment and a storage medium. The method comprises the steps of obtaining current flow information corresponding to current time; determining a target refining time period corresponding to the current time in a current flow period, wherein the current flow period is divided into a plurality of refining time periods according to a preset time granularity; obtaining target reference flow information corresponding to the target refining time period, wherein the target reference flow information is obtained through calculation according to target historical flow information of a plurality of target historical flow periods in the target refining time period, and dividing the target historical flow period is divided intoa plurality of refining time periods according to the preset time granularity; and performing attack detection according to the target reference flow information and the current flow information. Themethod is high in attack detection accuracy.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an attack detection method, device, computer equipment and storage medium. Background technique [0002] With the rapid development and wide application of network technology, people use the Internet to obtain information in daily life and production activities. Devices on the Internet are often subjected to network attacks, such as distributed denial of service (Distributed Denial of Service, DDOS) attacks, DDOS attacks use multiple distributed attack sources to send a large number of data packets to the target object, to consume a large amount of network resources, resulting in the failure of the device Network services are paralyzed. Traditional attack detection generally determines a fixed traffic threshold. When the access traffic exceeds the set traffic threshold, an alarm is issued. However, the access traffic is not fixed, resulting in low accuracy of attack det...
