Basic methods of CDN defense against DDoS:

1. Ensure the security of the server system

First of all, make sure that there are no vulnerabilities in the server software to prevent attackers from invading. Make sure the server uses the latest system and comes with security patches. Delete unused services on the server and close unused ports. For servers running on the site, make sure they get the latest patches and there are no security vulnerabilities.

2. Hide the real IP of the server

Add CDN transfer to the front end of the server (Waf shield, 360webguard, accelerated music, domain name forwarding, etc.). If you have plenty of money, you can buy a high shield to hide the real IP of the server. The domain name is resolved using the name resolution of CDN IP, and all the resolved subdomains use the IP address of CDN. In addition, other domain names deployed on the server cannot be resolved using real IP resolution, all of which are resolved using CDN. Nanchang Yijibi
