DDOS attack roughly means: others control a large amount of false traffic to occupy your server resource configuration, the server resource configuration is limited, once the server resource is fully occupied, there will be reasons such as freeze, slow speed, and failure to open. It's like the mobile phone you use. Once the running memory is insufficient, you will not be able to open any app software. This is the general meaning of DDOS attacks, so how to defend against DDOS attacks?
Regardless of any type of Internet business, as long as it relies on the Internet, it needs a server to run. As long as the server is stopped, the website, program software, tools, apps, games, platforms, etc. will be immediately inaccessible as long as they rely on the server to run. , and there are many ways to cause the server to stop running, such as computer room adjustment and maintenance, program errors, insufficient configuration, incorrect settings, operation errors, encountering DDOS attacks, etc. Among them, such as computer room adjustments and DDOS attacks are uncontrollable , It’s okay to adjust and maintain the computer room, after all, the official maintenance is to provide better servers; it’s hard to say about DDOS attacks.
There are generally several ways to defend against DDOS attacks:
1. Upgrade and expand server resource configuration:
DDOS attacks and defenses are actually the consumption of server resource allocation, depending on who has enough and large resources, but this method of defense costs relatively high.
2. Defense series products:
For example, the high-defense cloud server, high-defense server, high-defense IP, etc., are specially used to defend against network attacks such as DDOS, so as to ensure that the website is safe from attacks and that users who visit normally are not affected.
3. Hide the real address of the server:
This kind of method is to prevent attacks, so that attackers cannot find the real attack target of the source site, and have no way to start. Common methods include CDN, reverse proxy server, and high-defense IP.
There are mainly the above methods to defend against DDOS attacks. At present, many webmasters have encountered DDOS attacks, and the main thing is that many small Internet companies in China do not pay much attention to network security, so that any small attack may cause server paralysis, which greatly reduces the cost of DDOS attacks.
