The network dimension is used to find the data source... but to be honest. generally, most of CC bots outside China are not easy to find

Linux DDOS and CC attack SolutionBackgroundNowadays, DDOS attacks are becoming more and more frequent. DDOS Denial-of-Service can be implemented without any technology. Some webmasters often report mysql 1040 errors on their websites, and their online users are less than one thousand, mysql configuration is fine. Generally, you need to pay attention to this situation. Your website may be attacked by CC atta
Websites are classified as network security. Therefore, attacks against websites are also classified as attacks. Fortunately, most of the time it was scanning and stepping on the site, there were 80 thousand million attempts to use a security monitoring software to detect the most attacks a day ......However, due to security software installed, General SQL injection and other attacks are still okay-until CC attacks occur.The initial manifestation is t

The defense system is at the application layer, which effectively prevents the abuse of server resources by illegal users:

If you have read the touch code in the sample, you will find a CC in the sample. node_touch_capture_event event, and CC. node_touch_event is an engine-level event like a touch event. Let's take a look at its differences with a touch event.
A touch capture event has a higher priority than a touch event. In other words, a touch capture event responds first than a touch event and has the right to send a touch

We can use iptables to some extent to realize the ability of the black hole to resist CC (connection depletion) attacks, which are configured in detail as follows:1. System Requirements:1) LINUX kernel version: 2.6.9-42 elsmp or 2.6.9-55 ELSMP(Other kernel versions need to recompile the kernel, which is cumbersome, but can be implemented)2) iptables version: 1.3.72.

PHP anti-CC attack implementation code. In this case, your statistical system (which may be quantum or Baidu) cannot be used. However, we can use some anti-attack software to achieve this. However, sometimes the results are unclear. in this case, your statistical system (which may be quantum or Baidu) is of course not statistical. However, we can use some anti-attack software, but the effect is sometimes not obvious. Next I will provide a piece of PHP
