01 Security

Is port 4072 dangerous?

We have no specific security note for port 4072. 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 4072, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4072'      # process listening on 4072
sudo lsof -nP -i :4072

macOS

sudo lsof -nP -i :4072

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4072 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4072
netstat -ano | findstr :4072

From another machine

nmap -p 4072 -sV <host>
sudo nmap -sU -p 4072 <host>
nc -zv <host> 4072

Block it in the firewall

sudo ufw deny 4072/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 4072" -Direction Inbound -LocalPort 4072 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 4072 used for?

Port 4072 is assigned by IANA to zieto-sock (Zieto Socket Communications).

Is port 4072 TCP or UDP?

Port 4072 is registered for TCP and UDP.

Is it safe to open port 4072?

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 4072 is open?

On Linux run "ss -ltnup 'sport = :4072'", on macOS "lsof -nP -i :4072", and on Windows "netstat -ano | findstr :4072" to see the local process. From another machine, "nmap -p 4072 <host>" shows whether it is reachable.
