CC attack means that attackers use a large number of malicious requests to occupy server resources, so that normal users cannot access the website. Anti-ddos servers usually have higher bandwidth and stronger protection capabilities, which can effectively protect the server from being affected by CC attacks.

Anti-ddos servers usually adopt multi-level defense strategies, including traffic cleaning, blacklist filtering, whitelist access control, etc., to protect servers from DDoS attacks. Some Anti-ddos servers are also equipped with professional defense hardware, such as DDoS firewalls and load balancers, to more effectively defend against CC attacks.

The Anti-ddos server uses a series of technical means to defend against CC attacks. The main principles are as follows:

1. Bandwidth expansion: CC attacks are characterized by a large amount of request traffic, and the anti-defense server can respond to a large number of traffic requests by expanding the bandwidth capacity.

2. IP blocking: The Anti-ddos server will monitor and identify the IP address of the attack source. Once a large amount of request traffic is found to come from a certain IP address, it will immediately block the IP address, thereby effectively preventing attacks .

3. Intelligent cleaning: The Anti-ddos server adopts intelligent cleaning technology to analyze and filter request traffic, and filter out normal request traffic by detecting user access behavior, browser characteristics, geographical location, etc., thereby eliminating attack traffic and reducing server load .

4. Security protection software: Anti-ddos servers are usually equipped with professional security protection software, such as DDoS cleaning equipment, WAF, IPS, etc., which can effectively identify and defend against various CC attack methods.

It should be noted that although Anti-ddos servers can defend against CC attacks, attackers continue to evolve and improve attack techniques, so Anti-ddos servers also need to continuously upgrade their defense capabilities. In addition, if the attack traffic is too large, the Anti-ddos server may not be able to completely resist the attack. Therefore, it is recommended to choose sufficient bandwidth and protection capabilities when purchasing a Anti-ddos server to ensure the safe and stable operation of the server.
