  • Close the port if nothing on the host needs it.
  • 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.

Get-NetTCPConnection -LocalPort 8322 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8322
netstat -ano | findstr :8322

From another machine

nmap -p 8322 -sV <host>
sudo nmap -sU -p 8322 <host>
nc -zv <host> 8322
