What is a high defense server? High defense server refers to the type of server with independent single defense of more than 50G, which can provide network security maintenance for a single customer. High-defense server mainly refers to an independent server with a hard defense of more than 50G [1], which can provide security maintenance for a single customer. Generally speaking, it belongs to a kind of server. According to the environment of each IDC computer room, some provide hard defense and some use soft defense. To put it simply, server types that can help website denial of service attacks, regularly scan existing network master nodes and find possible security vulnerabilities can be defined as high-defense servers.

First, the principle of high-defense server

1. Regularly scan for vulnerabilities to remove security risks

In addition to loopholes in any website, there will be some possible security risks. So if you want to avoid malicious attacks, you need to scan and clean them in time. While renting a high-defense server, the service will regularly clean up the loopholes and security risks of some websites, so as not to give attackers any opportunity. Generally speaking, most attackers attack the backbone nodes, so the service will scan the backbone nodes regularly to eliminate security risks. At the same time, the corresponding firewall will be configured in the backbone node. This can greatly improve the security of the website and reduce the risk of malicious attacks on the network.

two。 Use load balancing devices to greatly reduce malicious attacks

The use of load balancing equipment means to make full use of all network devices to ensure the security and stability of the network environment. It generally includes routers, firewalls and other devices. How is the defense of the high defense server carried out? When the outside world attacks, the router is the first to be attacked, and other machines are not affected at this time. Generally speaking, a dead router will be restored after a restart without causing any loss. But if there are other devices, it is very likely to lose data, and the process of turning on the server is also very long. If you use a load balancing device such as a router, after one is attacked and crashes, the other will work immediately, minimizing the attack of ddos.

Second, the characteristics of high-defense server

1. High security of adaptation service

When using a shared host, different users will have different permissions, which is a security risk. On the other hand, independent high-defense servers can set their own host permissions and freely choose firewalls and antivirus facilities. The server can set its own security policy, unlike virtual hosts, which are separated by system permissions and will not be affected by other websites. The independent high defense server supports automatic updating of system application software to reduce security risks.

two。 Strong ability to defend against ddos attacks

High-defense servers generally have two main characteristics when defending against high-traffic attacks. One is to place the high bandwidth occupied by the traffic, and the other is the firewall traction system with intelligent identification of the traffic. Therefore, the defense against ddos attacks is still very strong.

3. Exclusive computer hardware resources

The shared host is a shared resource, and the server is slow to respond and connect. The independent high-defense server can choose enough network bandwidth resources and server grade to ensure the host response and the high speed of the network. In an independent host environment, you can closely check and test your own behavior and procedures to maximize the stability of the server.

About the characteristics of the high defense server is shared 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.
