01 Security

Is port 5406 dangerous?

We have no specific security note for port 5406. 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 5406, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5406'      # process listening on 5406
sudo lsof -nP -i :5406

macOS

sudo lsof -nP -i :5406

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5406 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5406
netstat -ano | findstr :5406

From another machine

nmap -p 5406 -sV <host>
sudo nmap -sU -p 5406 <host>
nc -zv <host> 5406

Block it in the firewall

sudo ufw deny 5406/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5406" -Direction Inbound -LocalPort 5406 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5406 used for?

Port 5406 is assigned by IANA to systemics-sox (Systemics Sox).

Is port 5406 TCP or UDP?

Port 5406 is registered for TCP and UDP.

Is it safe to open port 5406?

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 5406 is open?

On Linux run "ss -ltnup 'sport = :5406'", on macOS "lsof -nP -i :5406", and on Windows "netstat -ano | findstr :5406" to see the local process. From another machine, "nmap -p 5406 <host>" shows whether it is reachable.
