01 Security

Is port 480 dangerous?

We have no specific security note for port 480. 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 480, and is it reachable?

Linux

sudo ss -ltnup 'sport = :480'      # process listening on 480
sudo lsof -nP -i :480

macOS

sudo lsof -nP -i :480

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 480 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 480
netstat -ano | findstr :480

From another machine

nmap -p 480 -sV <host>
sudo nmap -sU -p 480 <host>
nc -zv <host> 480

Block it in the firewall

sudo ufw deny 480/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 480" -Direction Inbound -LocalPort 480 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 480 used for?

Port 480 is assigned by IANA to iafdbase (iafdbase).

Is port 480 TCP or UDP?

Port 480 is registered for TCP and UDP.

Is it safe to open port 480?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 480 is open?

On Linux run "ss -ltnup 'sport = :480'", on macOS "lsof -nP -i :480", and on Windows "netstat -ano | findstr :480" to see the local process. From another machine, "nmap -p 480 <host>" shows whether it is reachable.
