It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 11162 is open?

On Linux run "ss -ltnup 'sport = :11162'", on macOS "lsof -nP -i :11162", and on Windows "netstat -ano | findstr :11162" to see the local process. From another machine, "nmap -p 11162 <host>" shows whether it is reachable.
