  • 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 7281, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7281'      # process listening on 7281
sudo lsof -nP -i :7281

macOS

sudo lsof -nP -i :7281

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7281 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7281
netstat -ano | findstr :7281

From another machine

nmap -p 7281 -sV <host>
sudo nmap -sU -p 7281 <host>
nc -zv <host> 7281

Block it in the firewall

sudo ufw deny 7281/tcp                                         # Linux (ufw)
