+## Security
+- **Never commit `.env`** – it contains passwords and API keys. Only `.env.example` is tracked.
+- **SSH host key verification**: For secure SFTP transfers, provide a `known_hosts` file:
+  ```bash
+  ssh-keyscan -p 22 192.168.1.1 > known_hosts
+  ```
+  Mount it in `docker-compose.yml` and set `SSH_KNOWN_HOSTS=/ssh/known_hosts`.
+  Without it, any host key is accepted (MITM risk on untrusted networks).
+- **Basic Auth** protects the WebGUI but transmits credentials in cleartext over HTTP. Use a reverse proxy with HTTPS (e.g. Traefik, Caddy) in production.
