How to do a good DDoS defense, I believe that many inexperienced people do not know what to do. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

DDoS attack is a sharp weapon in the hands of hackers, a headache for all operators, and a powerful opponent that any company will be frightened to hear of. DDoS's full name is Distributed Denial of Service, which means "distributed denial of service" in Chinese. Is the use of a large number of legitimate distributed servers to send requests to the target, resulting in server congestion and can not provide normal services, can only announce game over.

From the perspective of enterprise customers, DDoS defense is a long process, attack methods and tools will be constantly refreshed, so how to do a good DDoS defense? F5 gives four suggestions!

The first suggestion is that users need to realize that network attack and defense and compliance are two different things, and security deployment should not aim at compliance, but should focus on attack and defense and put attack and defense in the first place.

The second suggestion is that users need to change the unified security policy. for key applications, they need to configure the security policy according to different grayscale traffic after finishing the fine division of the application traffic. The attack and defense model of F5 product + service has been proved to be effective by many users and can be used for reference.

The third suggestion is not to pin all the security defense capabilities on the fully automatic security mode, on the other hand, full automation also means security risks, and the best way to deal with it is to do controllable risk management.

The fourth suggestion is to choose transparent mode and Bypass mode carefully! Many customers are attacked because of these two modes, and the ultimate goal of today's DDoS attacks is not to paralyze the business, but to cover up lawbreakers stealing core data like no man's land after thoroughly penetrating transparent mode and Bypass mode. The solution given by F5 is to build a super-flexible full-agent architecture to deal with modern attack and defense.

Under the framework of F5's Advanced WAF (API Security-- next-generation WAF) + service, after big data's collection, machine learning and intelligent baseline judgment, all the work of the final plan is completed by F5, and the customer decides whether to enter the defensive state through "one-click switching". " F5 uses machine learning to judge normal traffic, abnormal traffic and user behavior, then deals with it by AIOps, and finally gives the customer the right to choose.

Attack and defense is the first goal, traffic precision is the realization method. What F5 hopes to achieve is to build a complete DDoS defense system through one-click operation after machine learning, rather than simply fully automatic.

After reading the above, have you mastered how to do a good job in DDoS defense? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
