- Identify the process that listens on it (commands below) before opening it in a firewall.
- Expose a service only to the networks that use it.

On Linux run "ss -ltnup 'sport = :7509'", on macOS "lsof -nP -i :7509", and on Windows "netstat -ano | findstr :7509" to see the local process. From another machine, "nmap -p 7509 <host>" shows whether it is reachable.
