01 Security

Is port 3480 dangerous?

We have no specific security note for port 3480. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:

  • Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
  • Never expose them to the Internet.
  • Rotate tokens and certificates and audit who has access.

03 Check it

Which program uses port 3480, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3480'      # process listening on 3480
sudo lsof -nP -i :3480

macOS

sudo lsof -nP -i :3480

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3480 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3480
netstat -ano | findstr :3480

From another machine

nmap -p 3480 -sV <host>
sudo nmap -sU -p 3480 <host>
nc -zv <host> 3480

Block it in the firewall

sudo ufw deny 3480/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3480" -Direction Inbound -LocalPort 3480 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3480 used for?

Port 3480 is assigned by IANA to plethora (Secure Virtual Workspace).

Is port 3480 TCP or UDP?

Port 3480 is registered for TCP and UDP.

Is it safe to open port 3480?

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. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.

How do I check if port 3480 is open?

On Linux run "ss -ltnup 'sport = :3480'", on macOS "lsof -nP -i :3480", and on Windows "netstat -ano | findstr :3480" to see the local process. From another machine, "nmap -p 3480 <host>" shows whether it is reachable.
