As the name implies, "high defense server" is a server that can resist DDoS/CC attacks for enterprises. 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 services. DDoS is an attack mode that exhausts the system resources of the attack target so that it can not respond to normal service requests. The protection system of DDoS is essentially an intelligent system based on resource competition and rule filtering. In view of the popular DDoS/CC flow attacks, DDoS high defense service can be effectively weakened by cloud cleaning cluster, database monitoring traction system and other technologies.

First, the advantages of high defense server

1. Protect against different attacks

The protection performance of the ordinary server is still relatively weak, if we must say why we choose the high-defense server, then the high-defense server can effectively help us to do a good job of protection. Our common SYN, httpget and other attacks can be weakened by high-defense servers, which can play a good protection function. And it can provide more than 60G protection capability, especially many websites have some special protection requirements, then you can also directly choose a high-defense server, because it can provide dynamic defense against CC attacks, etc., effectively ensure the security of our website.

two。 Effectively ensure to meet the requirements of network security

Now many websites are directly related to some confidential content, as well as the corresponding bank card information, so it is necessary to ensure a high degree of protection. With the increase in the number of Internet attacks, webmasters have a higher demand for security. Why choose a high-defense server, or from the overall performance point of view. If our website itself needs high protection security, we must choose an independent high-defense server, which can effectively do a good job of security protection, but also can find out the loopholes of the website, which can make our website more perfect.

Second, the defense mode of high-defense server

1. Configure the firewall on the node

For the risks caused by malicious network attacks, the configuration of firewalls on nodes can filter automatically, which greatly improves network security.

2. Scan nodes periodically

Many IDC services scan backbone nodes regularly to clean up possible security risks and because most malicious network attacks attack backbone nodes.

3. Sufficient bandwidth

The computer room where the high-defense server is located generally has extra bandwidth. after all, bandwidth consumption attack is one of the main forms of network malicious attacks, and a large number of attack packets will lead to server bandwidth congestion.

4. Filter unnecessary IP and ports

The high-defense server can filter out fake IP on the router and only open the service port to shut down the rest of the port. For example, the XX server only opens port 80 and closes other ports or makes a blocking policy on the firewall.

About the advantages of high-defense server which are 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.
