How to Deal with the CC Attack

The two mainstream attacks are divided into DDOS and CC attacks. The commonly encountered attacks on websites are CC attacks. Then, how should websites be dealt with by CC attacks?
 

1. By setting the black and white list

Observe log statistics to determine the IP that issued the attack, and set a blacklist in the background to block a certain IP segment to resist some small attacks. Of course, the black and white list needs to be managed frequently. When it is not easy to distinguish, it is easier to add the misoperation of normal users to the black list.

2. Change the port

If the attacker mainly launches the attack by attacking the port, we can defend the attack by modifying the port.

3. Replace the server

If the previous server configuration and defense are not enough, you can choose a higher configuration server and replace it. However, this method is not recommended by the editor. After all, if the server is replaced, the program will be interrupted, which will bring certain losses to the website operators.

4. Defend by adding CDN to the outer layer of the server

If you have used a high-defense server and still cannot defend against attacks, if you do not want to change the server, you can choose to add CDN nodes to defend against attacks. Adding a CDN node can not only speed up the user's access speed, but also divert the access traffic. All visits will not go directly to the origin site, but are processed on the CDN node. So once you encounter malicious attack traffic, the traffic will not go directly to the source site, but also directly hit the CDN node.

The above are some of the ways to deal with the website when the website is attacked by CC. Of course, website administrators should also pay more attention to network security, and try to prevent attacks before they come.
