In the daily operation and maintenance process, many operation and maintenance personnel think that CDN can only speed up the website. In the early stage of project operation, they did not do enough work on website security protection. Once a ddos attack or cc attack comes, the server will directly shut down, and the business not functioning properly.

Can CDN only speed up the website? CDN can not only distribute accelerated static resources for the website, but also hide the source server IP, so that ddos attacks cannot lock the source site for attack. However, most of the CDNs on the market can only help the website speed up, but Can't really play a protective role.

First of all, in the face of ddos attacks, the acceleration nodes used by ordinary cdn service providers are ordinary unprotected machines. If the attacker conducts ddos attacks on the nodes, the website of the node fault user cannot be accessed normally. Secondly, in the face of malicious cc attacks , Most of the manufacturers do not have good defense measures against cc attacks, and they may also bring large traffic bills to users. It is not uncommon to be charged hundreds of thousands of traffic charges overnight.

High-defense CDN can help users truly solve hidden dangers of attacks. Most CDN nodes use high-defense machine nodes to accelerate user websites. In case of DDos attacks, CDN has the function of intelligent second-level response, which can realize offline and switch within seconds Node, after the attack stops, the system will automatically restore more nodes to accelerate the distribution. In terms of cc attack, the high-defense CDN has an absolute advantage. It not only has 5 defense forms, but also can customize WAF defense rules according to the attack. The configuration is suitable own rules.

Users can choose a suitable package to access according to the daily needs of the site. After the package data is used up, there will be no high bills or arrears. The real integration of high-defense and CDN allows users to experience high-availability and cost-effective acceleration.
