Abstract

The invention discloses a processing method and system of a denial of service attack, a Web application firewall (WAF), and a router, is mainly applied to a CC attack process, and relates to the technical field of Internet, mainly for the purpose of solving the problem of threatening security of a target website when the target website is attacked in a time interval of cloud protection performed by a cloud server in the prior art. The method provided by the technical scheme comprises the following steps: a WAF obtaining access information of the target website; performing superposing processing on the access information and performing real-time monitoring on the superposed access information; and if it is monitored that the superposed access information exceeds a preset access threshold, performing interception processing on the access information.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a processing method for denial of service attacks, a WAF, a router and a system. Background technique [0002] Distributed Denial of Service (DDoS) attack refers to the use of client / server technology to combine multiple computers as an attack platform to launch a Denial of Service (DOS) attack on one or more targets. Thereby improving the damage degree of DOS attack. With the development of the Internet, DDoS attacks also develop, and there are more and more types of DDoS attacks. Among them, CC (Challenge Collapsar) attack is a type of DDoS attack. CC attacks are mainly used to attack website pages, simulating multiple Users keep visiting a target website, occupying a large amount of central processing unit (Central Processing Unit, CPU), causing the server resources to be exhausted until it crashes. [0003] At present, CC attacks can be prevented through cloud protecti...
