HTTP honeypot technology in Nginx

HTTP honeypot technology refers to simulating a website or web application in order to detect and block potential attackers. In this process, honeypots serve as bait to attract attackers in order to identify and learn attack techniques and strategies, and find vulnerabilities to improve. Currently, HTTP honeypot technology is widely used in the security protection of websites and web applications. Nginx is a high-performance web server that has some great HTTP honeypot technology to protect websites from attacks.

1. Access Log module

Nginx Access Log module can capture information including request method, URL, HTTP status code, request source and visitor IP address. The Access Log module provides some extremely useful data for HTTP honeypot technology. This data can be used to create a dummy website or web application to provide attacker bait.

You can use the following configuration to add the Access Log module to the Nginx configuration file.

http {
    ...
    access_log path format;
    ...
}

2. Error Log module

The Nginx Error Log module can record all web server errors. These errors include syntax errors, file not found, and invalid requests, as well as most error types. The Error Log module can provide more data for HTTP honeypot technology, allowing you to better monitor potential attackers and more easily protect your servers through learning and improvement.

You can use the following configuration to add the Error Log module to the Nginx configuration file.

http {
    ...
    error_log path;
    ...
}

3. Rewrite module

Nginx Rewrite module can rewrite URL request paths using regular expressions. You can use the Rewrite module to create a virtual website that looks like a real website or web application. This dummy website can be used with HTTP honeypot techniques to lure attackers in.

The following is a simple Rewrite module configuration example:

http {
    ...
    server {
        listen 80;
        server_name honeypot.example.com;
        rewrite ^(.*)$ https://maybefakesite.com$request_uri? redirect;
    }
    ...
}

4. HTTP Referer module

Nginx HTTP Referer module can capture the access point from which website own website, which provides a more comprehensive security guarantee for HTTP honeypot technology. With the help of the HTTP Referer module, you can log the origin of requests, identify attackers’ intentions, and learn improvements.

You can use the following configuration to add the HTTP Referer module to the Nginx configuration file.

http {
    ...
    server {
        listen 80;
        server_name honeypot.example.com;
        if ($http_referer ~* (badreferer.com|anotherbadsite.com)) {
            return 403;
        }
    }
    ...
}

5. Limit_req module

Nginx Limit_req module can limit the request frequency, which is very effective in dealing with DoS or DDoS attacks. At the same time, it is also a good choice for HTTP honeypot technology.

The following is an example of a Limit_req module configuration:

http {
    ...
    limit_req_zone $binary_remote_addr zone=honeypot:10m rate=1r/s;
    server {
        listen 80;
        server_name honeypot.example.com;
        location / {
            limit_req zone=honeypot burst=5 nodelay;
            ...
        }
    }
    ...
}

When using HTTP honeypot technology, it is very important to maintain the current attack mode and situation. You need to closely monitor the activity taking place on your virtual website or web application in order to understand the attackers' strategies and tools. Learning to improve your honeypot and Nginx configuration is an ongoing process as you learn more harmful behaviors and attack strategies. Nginx is a very powerful HTTP server that provides some great HTTP honeypot technology to protect your website security.
