Is port 1479 dangerous?

We have no specific security note for port 1479. Its risk depends on the program actually listening on it. General advice for other services services:

  • 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 1479, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1479'      # process listening on 1479
sudo lsof -nP -i :1479

macOS

sudo lsof -nP -i :1479

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1479 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1479
netstat -ano | findstr :1479

From another machine

nmap -p 1479 -sV <host>
sudo nmap -sU -p 1479 <host>
nc -zv <host> 1479

Block it in the firewall

sudo ufw deny 1479/tcp                                         # Linux (ufw)

On Linux run "ss -ltnup 'sport = :1479'", on macOS "lsof -nP -i :1479", and on Windows "netstat -ano | findstr :1479" to see the local process. From another machine, "nmap -p 1479 <host>" shows whether it is reachable.
