# Nginx WAF Rule Snippets
|
||||||
|
|
||||||
|
This directory contains Nginx WAF rule snippets generated from OWASP rules.
|
||||||
|
You can include these snippets in your existing Nginx configuration to enhance security.
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
1. Include the rule snippets in your `server` or `location` block:
|
||||||
|
```nginx
|
||||||
|
server {
|
||||||
|
# Your existing configuration
|
||||||
|
include /path/to/waf_patterns/nginx/*.conf;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
2. Reload Nginx to apply the changes:
|
||||||
|
```bash
|
||||||
|
sudo nginx -t && sudo systemctl reload nginx
|
||||||
|
```
|
||||||
|
|
||||||
|
## Notes
|
||||||
|
- The rules use `map` directives for efficient pattern matching.
|
||||||
|
- Blocked requests return a `403 Forbidden` response by default.
|
||||||
|
- You can enable logging for blocked requests by uncommenting the `access_log` line.
