Abstract

The invention provides a network attack detection method and device. The method comprises the following steps: acquiring a plurality of target access requests which belong to the same session and aresent to a target server by a target terminal; determining a detection feature item, and determining an access feature value of the detection feature item according to the plurality of target access requests; obtaining a target detection rule corresponding to the detection feature item; judging the access characteristic value by using a target detection rule to obtain a first attack detection result; wherein the first attack detection result is used for representing whether a network attack behavior on the same session exists or not. The multiple target access requests of the same session are detected as one group to extract the access characteristic values, and the information carried by the extracted access characteristic values is more comprehensive, so that the attack detection accuracyis higher.

Description

technical field [0001] The present invention relates to the technical field of network security, more specifically, a network attack detection method and device. Background technique [0002] On the Internet, the process of interaction between a terminal and a server may be attacked by malicious programs such as hackers. In order to ensure the security of network access, an application firewall is usually deployed on the access path between the terminal and the server, and based on the protection rules of the application firewall, attack detection and attack processing are performed on the access process. [0003] At present, there are two main forms of application firewalls: one is to use the hardware server as the main body of the firewall, which is connected to the network topology in the form of an independent device; the other is to use the cloud application firewall to modify the DNS resolution method of access requests Integrate Cloud Application Firewall into networ...
