Problems solved by technology

[0003] High cost: Purchasing professional DDOS protection services costs tens of thousands of yuan per month, and hundreds of thousands of yuan a year, which is overwhelming for small and medium-sized companies and start-up companies
[0004] Low performance: The general practice in the industry is to clean and filter traffic, but this adds an additional layer of processing, which consumes an additional layer of time

Embodiment Construction

[0033] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, the DDOS defense method based on the fault automatic migration system includes:

[0035] Step S1, during domain name resolution, determine whether each VIP address in the VIP cluster is attacked by DDOS;

[0036] Step S2, if the judgment result is yes, the VIP address attacked by DDOS is discarded, and the traffic is directed to the VIP address not attacked;

[0037] Step S3, if the judgment result is no, then guide the traffic balance to each VIP address in the VIP cluster.

[0038] According to the DDOS defense method based on the fault automatic migration system of the embodiment of the present invention, the technology of automatic migration is adopted to avoid the attack traffic, the attacker generally attacks the VIP, and the VIP attacked by the DDOS will be automatically abandoned, and th...

Abstract

The present invention relates to the technical field of network security and in particular to a DDOS defense method and system based on a fault automatic migration system, wherein the DDOS defense method includes: determining whether each VIP address in a VIP cluster is attacked by DDOS during domain name resolution; if so, discarding the VIP addresses attacked by the DDOS, and guiding the trafficto the VIP addresses that are not attacked; and if not, uniformly guiding the traffic to each VIP address in the VIP cluster. The technical solution of the present invention realizes the avoidance ofattack traffic by the automatic migration. An attacker generally attacks the VIPs, and the DDOS attacked VIPs are automatically discarded, and the normal traffic is guided to other VIPs that are notattacked, thereby preventing the server from being attacked, solving the problem of DDOS attack, and greatly reducing the cost and the difficulty of use.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a DDOS defense method and system based on a fault automatic migration system. Background technique [0002] With the popularization and development of Internet applications, everyone pays more and more attention to user experience, so there are many DDOS (Distributed Denial of Service Attack) products on the market. At present, high-defense IP is generally used, followed by a powerful processing cluster. The cluster analyzes the traffic, adopts technologies such as human-computer identification and anomaly detection, to clean and filter the traffic, and only allows legitimate traffic. Traffic is shielded or discarded to protect against DDOS. The disadvantages of existing DDOS protection methods are obvious: [0003] High cost: Purchasing professional DDOS protection services costs tens of thousands of yuan per month, and hundreds of thousands of dollars a year, which i...
