- Bind the service to localhost or a private network, never to a public address.
- Enable authentication, use per-application accounts and require TLS.
- Watch for exposed Docker ports: publish them on 127.0.0.1 only.

From another machine
nmap -p 2273 -sV <host> sudo nmap -sU -p 2273 <host> nc -zv <host> 2273
