Problems solved by technology

However, CDN is very effective in DDoS defense for static resources, and for common dynamic resources, this method will cause a large number of back-to-source visits, resulting in a large number of false killings and occupying a large amount of bandwidth

Abstract

The present invention provides a dispatching system-based DDoS (distributed denial of service) defense method and a DDoS (distributed denial of service) defense system. The method includes the following steps that: when a DDoS attack to a first IP address is monitored, a currently available second IP address is obtained; and when a dispatching request sent by a user terminal which accesses the first IP address is received, the second IP address is sent to the user terminal, so that the user terminal can access a service target through the second IP address. With the dispatching system-based DDoS (distributed denial of service) defense method provided by the embodiments of the present invention adopted, influences of the DDoS attack can be reduced to a controllable range, defense cost can be reduced, influence on the service target accessed by a user which is caused by wrong attack killing can be greatly reduced, and the experience of a user subjected to attacks can be improved.

Description

technical field [0001] The present application relates to the technical field of network security, and in particular, to a DDoS defense method based on a scheduling system and a DDoS defense system. Background technique [0002] DDoS (Distributed Denial of Service) attack refers to the use of client / server technology to combine multiple computers as an attack platform to launch DDoS attacks on one or more targets, thereby multiplying the risk of denial of service attacks. power. The principle of a DDoS attack is to find the resource bottleneck of the attacker, and to make the victim's business unavailable by consuming resources. Current relevant defense solutions include: [0003] DDoS traffic cleaning: The most commonly used method of preventing DDoS at present. It detects DDoS attacks through DDoS detection devices and warns them. When a DDoS attack is found, the bypass traffic cleaning device is notified to pull the traffic of the attacked destination IP, clean the atta...
