Cc attack and what its solution is, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

Understanding cc attacks is the only way to solve them.

The full name of CC attack: ChallengeCollapsar, which means to challenge a black hole in Chinese, because the previous security devices that resist DDoS attacks are called black holes. As the name implies, challenging black holes means that there is no way for black holes to take this kind of attack. The new generation of anti-DDoS devices have been renamed ADS (Anti-DDoSSystem), which can basically perfectly resist CC attacks. Many of today's anti-ddos devices ADS have been able to ignore CC.

The principle of CC attack is to simulate multiple users to visit the dynamic pages of the target website through a proxy server or a large number of broilers, create a large number of background database query actions, consume target CPU resources, and cause denial of service.

Unlike DDoS, which can use hardware firewalls to filter attacks, requests from CC attacks are normal requests.

We all know that the pages of the website can be divided into static and dynamic, dynamic pages need to interact with the background database, for example, when some forum users log in, they need to go to the database to query your level, permissions, etc., and when you leave a message, you need to query permissions, synchronize data, and so on, which consumes a lot of CPU resources, resulting in static pages that can be opened. However, dynamic web pages that need to interact with the database open slowly or cannot be opened.
