This article mainly introduces "how servers resist DDOS attacks". In daily operation, I believe many people have doubts about how servers resist DDOS attacks. Xiaobian consulted various materials and sorted out simple and easy operation methods. I hope to help you answer the doubts about "how servers resist DDOS attacks"! Next, please follow the small series to learn together!

How does the server defend against DDOS attacks? With the rapid development of the Internet, people's work and life are increasingly dependent on the Internet. The number of domestic websites has increased significantly every year. Good servers can build good websites. Recently, hacker attacks often occur. How can servers resist DDOS attacks?

Dealing with DDoS is a systematic project. It is unrealistic to rely solely on a certain system or product to prevent DDoS. It is certain that it is impossible to completely eliminate DDoS at present, but it is possible to resist 90% of DDoS attacks through appropriate measures. Based on the cost of both attacks and defenses, if the ability to resist DDoS is enhanced through appropriate methods, it means increasing the attack cost of attackers. Then most attackers will not be able to continue and give up. This is equivalent to successfully defending against DDoS attacks. The following is the author's experience and suggestions to resist DDoS over the years and share with you!

1. Use high-performance network equipment

First of all, it is necessary to ensure that network equipment cannot become a bottleneck, so when choosing routers, switches, hardware firewalls and other equipment, we should try to choose products with high popularity and good reputation. It is also better if there is a special relationship or agreement with the network provider, and when a large number of attacks occur, it is very effective to ask them to do traffic control at the network junction to combat certain types of DDoS attacks.

Avoid the use of NAT as much as possible.

Whether it is a router or a hardware protection wall device, we should try to avoid the use of NAT, because using this technology will greatly reduce the network communication capacity, in fact, the reason is very simple, because NAT needs to translate the address back and forth, and the translation process needs to calculate the checksum of the network packet, thus wasting a lot of CPU time, but sometimes NAT must be used, and there is no good way.

How do servers defend against DDOS attacks? If you have read the above article content, for the server how to resist DDOS attacks believe that everyone has a number of hearts, DDOS attacks have many different forms of expression, subdivided is very complex, it is recommended that you choose high defense server, defense ability is relatively strong.

At this point, the study of "how to resist DDOS attacks on servers" is over, hoping to solve everyone's doubts. Theory and practice can better match to help everyone learn, go and try it! If you want to continue learning more relevant knowledge, please continue to pay attention to the website, Xiaobian will continue to strive to bring more practical articles for everyone!
