First of all, we need to understand what is a high-defense server? a high-defense server can assist a website in a denial of service attack, and regularly scan the existing network master node to find the types of servers that may have security vulnerabilities. These can be defined as high-defense servers.

With the rapid development of the Internet, the Internet environment is getting worse and worse, and there are more and more malicious attacks. Whether it is formal enterprise website, game website, shopping website or chess and card room, entertainment website, many users break up because of all kinds of network attacks, the server is forcibly closed, customers can not visit, and then lead to the loss of interests.

In order to deal with the above problems, the high defense server application is born. However, there are many suppliers of high-defense servers in the market, and they provide a variety of protection, so as users, we should also understand that compared with ordinary servers, high-defense servers can really protect against malicious attacks?

Baidu encyclopedia also explained that high-defense server refers to an independent single protection of more than 10G server type, which can be considered as a single customer to provide network security maintenance of the server type. According to the environment of each IDC computer room, high defense server can be divided into software protection, hardware protection and skill protection.

Software protection is a kind of maintenance barrier between the intranet and the extranet by using the software firewall parasitic on the operating platform. Because most of the malicious attacks on the network are attacks on the master node of the network, and the software firewall will regularly scan the master node of the network to find the possible security risks and clean them up in time, so as not to give the offender a chance.

Hardware protection mainly refers to the bandwidth redundancy of the computer room and the processing speed of the machine. One of the ways of malicious attacks on the network is bandwidth-consuming attacks. Our common server bandwidth congestion is caused by a large number of intrusion data packet congestion, which requires sufficient bandwidth redundancy in the computer room of the high-defense server location. the processing speed of the server is fast, all of which can be used to protect against attacks.

Skill protection mainly refers to the supplier's ability to deal with the invasion. Among them, the flow traction skill is a new type of skill protection, which can separate the normal flow and the attacking flow area, and draw the attacking flow to the protective equipment, instead of selecting itself to resist it. On the other hand, if the firewall is equipped on the main node, it can filter the malicious attacks of the network, greatly improve the network security and reduce the danger caused by the malicious attacks of the network. Now, even if the high-defense server has set up a variety of protection measures on the backbone nodes, it can ignore CC attacks and protect DDOS attacks, basically ignoring wanton network attacks. Even though the high-defense server will filter the fake IP and shut down the remaining ports and make blocking policies on the firewall, then prevent others from invading through other remaining ports.

When selecting high-defense servers, enterprises and individuals should first consider whether the protection is appropriate, whether the server is stable, whether the server equipment is good or not, and the most important thing is to choose a regular IDC company.

To sum up, the size of the protection capability of selecting servers should be considered according to their own costs and needs. Do not choose blindly, it is best to select the computer room that can be upgraded to protect in the future. This can not only control the cost of expenditure, but also play a good protective effect, otherwise be invaded, serious will also lead to server paralysis, the loss of the enterprise is huge.
