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

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:
