What Is a CC Attack?
In a challenge collapsar (CC) attack, the attacker uses a proxy server to generate and send disguised requests to the target host. In addition, the attacker controls other hosts in the Internet and makes them send large numbers of data packets to the target server to exhaust its resources. In the end, the target server stops responding to requests. As you know, when many users access a web page, the page opens slowly. So in a CC attack, the attacker simulates a scenario where a large number of users (a thread represents a user) are accessing pages all the time. Because the accessed pages all require a lot of data operations (consuming many CPU resources), the CPU usage is kept at the 100% level for a long time until normal access requests are blocked.
You can use the CC defense function to control the HTTP request rate.
