After all the system security defenses are completed, I am afraid SQL injection, cross-site attacks, and other web Application Layer defenses are left behind. This is also the most troublesome thing for the majority of webmasters.Security treasure Architecture Technical speculation and advanced network security defense"Explains one of the simplest high-performance defense methods. You can handle most of the attacks with slight modifications based on your own situation. But is everything okay?Fir
Security company Sucuri said in March 9 that hackers used more than 162000 WordPress websites to launch DDoS attacks to the target website. all requests were random values (such? 4137049643182 ?), Therefore, the cache is bypassed, forcing every page to be reloaded.

Two questions are raised in the video:
1. Use security protection solutions to prevent attacks.
2. When an attack occurs, the system can promptly trigger an alarm, block the attack, and record the hacker behavior characteristics.
The current website topology is as follows:
Through the video, Zhi Zhaoming's website was attacked by hackers and changed.
In the current website topology, there is only one Server Load balancer, which may be replace

Upload Vulnerability
use some interfaces that can be uploaded to inject malicious code into the server and then access it through a URL to execute code
Example: Http://www.rona1do.top/upload ... (Nginx will execute 1.jpg as PHP code)

Project Address: Https://github.com/loveshell/ngx_lua_waf?utm_source=tuicoolutm_medium=referralRecommended Installation:
Recommend using lujit2.1 for LUA support
Ngx_lua if it is 0.9.2 above, it is recommended that the regular filter function be changed to ngx.re.find, matching efficiency will be increased by about three times times.
