  • 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.

03 Check it

Which program uses port 1288, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1288'      # process listening on 1288
sudo lsof -nP -i :1288

macOS

sudo lsof -nP -i :1288

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1288 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1288
netstat -ano | findstr :1288

From another machine

nmap -p 1288 -sV <host>
sudo nmap -sU -p 1288 <host>
nc -zv <host> 1288

Block it in the firewall
