For a long time, cyber attacks are the active black forces that we hate most as webmasters, and websites with good traffic may go down day by day because of frequent attacks. In particular, the DDos attack takes resources from the target network or server, resulting in a denial of service on the server. once the enterprise network is attacked, the consequences are unimaginable, so the high-defense server arises at the historic moment. Let's talk about how to select the high-defense server. one

How is the high defense server protected?

At present, the common type of website attack is mainly traffic attack, which is what we often call DDOS attack. The most basic DDoS attack is to use reasonable service requests to occupy too many service resources, so that legitimate users can not get the response of the service. CC attack is also a kind of traffic attack. CC simulates multiple users constantly visiting pages that require a lot of data operations, resulting in a waste of server resources. CPU is 100% for a long time, and there will always be endless connections until the network is congested and normal access is forced to stop.

Traffic attacks take up resources. If the resources are sufficient, such attacks will not have a great impact on the network. If the bandwidth of the server is not sufficient, the impact after the attack will be obvious. This requires the high defense server to have sufficient bandwidth. In addition, after renting a high-defense server, the service will have a hard defense range against traffic attacks. In this range, the traction system of the high-defense server will have a function to identify the traffic entering the server, and even if it is attacked by a network, the network of users within the protected range will not be affected. If the attack traffic exceeds the protected range, it will temporarily pull the IP. three

What knowledge is needed to select high-defense servers?

Therefore, we can clearly choose and buy the main point of the high-defense server: the bandwidth size. First of all, because many network attacks use bandwidth-consuming attack methods, so from the reverse thinking, the size of the bandwidth is one of the criteria to judge whether it is a high-defense server or not. Secondly, the size of the scope of defense, high-defense server data centers will have firewall equipment, observe and detect whether the firewall equipment is more than 1000G, at present, the highest foreign cluster firewall has been able to achieve T-level defense. Of course, the types of attacks that the high defense server can defend must also consider whether it can deal with common flooding attacks such as SYN, UDP, IMCP in the network layer, whether it supports web application protection functions such as HTTP feature filtering, URI filtering, host filtering, and whether it can effectively defend against abnormal message attacks such as frag flood,smurf,stream,flood,land,flood, and so on. In addition, because, after all, high defense servers have to run business, in addition to high defense, it is best to take into account the performance of the servers. You can compare and refer to the IOPS values of various cloud server vendors. In this way, you will be able to choose the best American high defense server.

The above describes what knowledge is needed to select a high-defense server. When selecting a high-defense server, enterprises and individuals need to consider not only the bandwidth, scope, and type of attack that can be defended, but also the stability of the server, poor configuration and other factors. The size of the defense capability should be determined according to the combination of the enterprise's own costs and needs, taking into account the needs of business expansion, it is best to choose a computer room that can upgrade the defense. This can not only control the expenditure cost, but also play a good defensive role, avoid server paralysis caused by attack, and bring huge losses to the enterprise.
