Prevent HTTP brute force cracking attacks in Nginx

Nginx is a high-performance web server and a tool for reverse proxy, load balancing and HTTP caching. The use of Nginx is becoming more and more widespread, and many people use Nginx as their web server, but preventing brute force attacks in Nginx has always been an important issue. This article will introduce some methods to prevent HTTP brute force attacks in Nginx.

1. Use password strength checking strategy

Password strength checking is a strategy for checking password strength. In Nginx, password strength checking policies can be used to prevent HTTP brute force attacks. Nginx can use multiple password strength checking methods, such as strong password policy, password complexity policy and password reuse policy. These policies can be configured as needed.

2. Use the anti-brute-force cracking plug-in

The anti-brute-force cracking plug-in is a protection mechanism used in Nginx. It can prevent brute force by limiting the number of clients connected at the same time and the access speed. Crack attack. You can use Nginx's rate limiting module to implement anti-brute-force cracking plug-ins. The rate limiting module can limit the connection rate and bandwidth of each client.

3. Use session management technology

Session management technology is a protection mechanism used in Nginx, which can prevent brute force attacks by tracking the status of each session. You can use Nginx's sticky session module to implement session management technology. The sticky session module can bind each client's session to a specific application server, ensuring that each session is handled correctly.

4. Use SSL/TLS protocol

The SSL/TLS protocol is a protection mechanism used in Nginx, which can prevent brute force attacks by encrypting communications. The SSL/TLS protocol prevents third parties from eavesdropping and tampering with communication traffic. You can use Nginx's SSL/TLS module to implement the SSL/TLS protocol.

To sum up, the above four methods can prevent HTTP brute force cracking attacks in Nginx. Different methods can be selected and combined according to actual needs. Using these methods can help you protect your Nginx server from brute force attacks and improve the security and stability of your website.
