Abstract

The invention aims to provide an attack protection method and device based on dynamic adjustment; the method comprises the steps: determining whether a target IP has packet loss or not according to the incoming flow of a source IP and the incoming flow of the target IP; when packet loss exists in the target IP, performing first adjustment processing on the current speed threshold value of the source IP according to the obtained current speed threshold value of the source IP, the current speed threshold value of the target IP and the current total flow of the target IP to obtain a new speed threshold value of the source IP; or, when the destination IP does not have packet loss, performing second adjustment processing on the current speed threshold of the source IP according to the obtained current speed threshold of the source IP, the current speed threshold of the destination IP, the current total flow of the destination IP and the current packet loss rate of the destination IP to obtain a new speed threshold of the source IP, thereby realizing dynamic adjustment of the current speed threshold of the source IP according to the system flow condition. According to the invention, mistaken interception rate is reduced, and meanwhile the defense effect and the user experience are improved.

Description

technical field [0001] The present application relates to the computer field, in particular to an attack protection method and device based on dynamic adjustment. Background technique [0002] In the existing technology, with the rapid development of the mobile Internet and the Internet of Things, more and more hardware devices with vulnerabilities are exposed on the Internet. Through the use of vulnerabilities, the scale of hackers controlled by hackers is also increasing. Hackers can easily launch large-scale DDOS attacks through a large number of bots under their control. The attack method of random source IP can be filtered through the real source IP authentication mechanism, but the real source IP attack can easily break through various source IP authentication mechanisms because of its complete protocol stack behavior and even real user access behavior. To achieve the attack effect, the access frequency of the attack source IP must be higher than that of the normal so...
