- Implement a Web Application Firewall (WAF) to filter suspicious POST/GET requests to Drupal administrative paths.
## Detection
- **Indicators of Compromise:** Monitor for unexpected administrative user creation, unauthorized file modifications in the `/sites/default/files` directory, or unusual outbound network traffic from the web server.
- **Detection methods and tools:** Use `drush pm-list` to check current module versions. Utilize security scanning tools like `Drupal Check` or `Audit` to identify outdated components.
