In this issue, the editor will bring you about how to solve the problem of the website being attacked by DDOS and how to use layer 7 protocol to defend. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

With the continuous progress of the mobile Internet data network, in order to provide you with a variety of convenience, the operation scale of DDoS attacks is also getting larger and larger, and now it has already entered the era of Tbps DDoS attacks. Not only the operation scale of DDoS attacks is getting larger and larger, but also the denial of service attacks are becoming more and more complicated. many traditional security countermeasures of ddos attacks have been unable to solve the evolving attack methods. In order to ensure that enterprises can thoroughly solve a variety of new ddos traffic attacks, enterprises must enhance and update the security protection countermeasures against ddos attacks. Next, SINE security protection will talk about which security protection countermeasures enterprises need to do well to solve the brand-new DDoS attacks in 2020.

1. DDoS security protection in the transport layer

The transport layer (L7) DDoS attack has long gone beyond the transport layer (L3Acer 4) attack and has become the most common attack scalar. According to the relevant data analysis, 32% of enterprises show transport layer attacks, compared with 38% of enterprises suffering from transport layer attacks. Among all kinds of attacks, httpsudp attack ranks first. In addition, SSL, DNS and SMTP attacks are all common transport layer attacks. This kind of development trend indicates that the modern DDoS security protection is not only for better security protection against transport layer DDoS attacks. In order to provide adequate protection for enterprises, contemporary DDoS security protection countermeasures must contain embedded security protection countermeasures that can protect against transport layer (L7) attacks.

2. SSL DDoS flood safety protection

At this stage, the total traffic of data encryption accounts for more than half of the total traffic of mobile Internet. About 75 per cent of the world's corporate websites are all delivered through HTTPS, a higher proportion in foreign and French sales markets. Unexpectedly, such increases also provide a key security test: compared with basic post requests, data encryption post requests will require about 15 times the system resources. This means that complex attackers can bring down a corporate website even with a small amount of total traffic. As more and more total traffic is encrypted, SSLDDoS flooding has become a more and more common attack scalar for hackers. Because of the lethality of SSL's DDoS attacks, high-quality security countermeasures that can protect against SSLDDoS floods are indispensable for enterprises that expect adequate protection.

3. Website DDOS security protection

Attackers are constantly looking for new ways to avoid traditional security measures and attack enterprises with attacks that have never been done before. Even if some minor changes are made to the attack machine code, hackers can create attacks that cannot be identified by manual machine code. Such attacks are commonly referred to as "cyber warfare" attacks. The most common cyber war attacks are large-bandwidth DDoS attacks and augmented attacks. According to relevant data analysis, 43% of enterprises have been attacked by large-bandwidth attacks, and 40% of enterprises claim to have suffered increased DDoS attacks. This kind of development trend shows the importance of the security protection role of cyber war attacks in contemporary DDoS security protection measures.

4. protect against the characteristic behavior of attack.

As DDoS attacks become more complex, it becomes more difficult to distinguish between reasonable and legitimate total traffic and intentional total traffic. The common measure chosen by many security manufacturers is to test the attack according to the total flow threshold and apply the speed limit to limit the maximum total flow. As everyone knows, this is also a kind of very rough attack blocking methods, because this kind of security protection methods can not distinguish between the real total traffic and the total attack traffic. Especially during the peak period of total traffic, simple security protection measures such as speed limit can not distinguish between reasonable legal total traffic and attack total traffic, and will eventually block reasonable and legitimate customers. Therefore, the selection of DDoS security protection countermeasures based on the test (and mitigation) of behavior analysis is indeed a necessary role in effective DDoS security protection.

The above is the editor for you to share how to solve the website by DDOS attacks and the use of layer 7 protocols for defense, if there happen to be similar doubts, you might as well refer to the above analysis to understand.
