Is port 3459 dangerous?

We have no specific security note for port 3459. 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 3459, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3459'      # process listening on 3459
sudo lsof -nP -i :3459

macOS

sudo lsof -nP -i :3459

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3459 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3459
netstat -ano | findstr :3459

From another machine

nmap -p 3459 -sV <host>
sudo nmap -sU -p 3459 <host>
nc -zv <host> 3459

Block it in the firewall

sudo ufw deny 3459/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3459" -Direction Inbound -LocalPort 3459 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 3459 used for?

Port 3459 is assigned by IANA to integral (TIP Integral).

Is port 3459 TCP or UDP?

Port 3459 is registered for TCP and UDP.

Is it safe to open port 3459?

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 3459 is open?

On Linux run "ss -ltnup 'sport = :3459'", on macOS "lsof -nP -i :3459", and on Windows "netstat -ano | findstr :3459" to see the local process. From another machine, "nmap -p 3459 <host>" shows whether it is reachable.
