What is a high defense server? High-defense server is a server that can resist DDoS/CC and other attacks. in the era of cloud computing, games, APP, finance, e-commerce and other businesses with demand can obtain this high-defense capability by accessing DDoS high-defense service.

I. the principle and defense mode of high-defense server

1. Network defense

And if we want to take a closer look at the defense way of the high-defense server, then in fact, among the high-defense servers on the Internet, there is another kind of server that strengthens the network defense. This kind of server is the same as the ordinary server in hardware, except that there is a special IP hidden design on the data, so that there is no way for outside attacks to directly find this server to attack. This is also a very effective form of defense.

2. Physical defense

Generally speaking, the high-defense server we come into contact with refers to the physical defense, that is, a layer of fire wall is added to the hardware that shuts down the server directly. such a hardware firewall is undoubtedly like a layer of "armor" of the server. can play a good defensive role. Therefore, the general default high-defense server is the high-defense server above this kind of physical defense, which can make everyone enjoy better defense through the promotion of hardware.

Second, how to choose a high defense server

1. Network resources

Bandwidth-High defense servers are mainly used to defend against network attacks, while most of the network attacks ddos attacks and cc attacks consume or occupy network resources. The bandwidth of the server should be large enough to play a certain role in defending against network attacks. At the same time, the size of the bandwidth affects the access speed of the website.

Line-the line is mainly divided into single-line, double-line and multi-line BGP. Single-line general default telecommunications line, double-line, that is, the combination of two lines, now the mainstream double-line is telecom + Unicom, telecom + mobile. High-defense server rental is divided into different types according to the line, although the two-line is more appropriate, but also according to their own budget and economic conditions.

two。 Hardware configuration

High-defense server is a kind of server, the composition of hardware configuration is also cpu, hard disk, memory and other factors, the specification, size and grade of the computer room affect the configuration of high-defense server. If the leasing aspect is adopted, the impact is more obvious; if it is hosting, the hardware configuration is borne by the user, and there is no need to worry about the server configuration of the computer room.

3. Defense capability

The choice of high-defense servers is mainly focused on defense capabilities, especially in industries that are vulnerable to network attacks. According to the concept, the defense capability of the high defense server is at least 50G. High-defense server is divided into stand-alone defense and cluster defense, choose and buy when to distinguish, can not be muddled to deal with. The stronger the defense capability, the higher the cost. We can use basic defense + elastic defense to defend against DDOS attacks and CC attacks. The choice of defense size should closely measure your own cost and the situation of being attacked on a daily basis, consider it together, and don't choose blindly.

On how to choose a high-defense server, you know how much to share here, I hope that the above content can have a certain reference value for everyone, you can learn to apply. If you like this article, you might as well share it for more people to see.
