01 Security

Is port 4414 dangerous?

We have no specific security note for port 4414. 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 4414, and is it reachable?

Linux

sudo ss -ltnup 'sport = :4414'      # process listening on 4414
sudo lsof -nP -i :4414

macOS

sudo lsof -nP -i :4414

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 4414 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 4414
netstat -ano | findstr :4414

From another machine

nmap -p 4414 -sV <host>
nc -zv <host> 4414

Block it in the firewall

sudo ufw deny 4414/tcp                                         # Linux (ufw)

Is port 4414 TCP or UDP?

Port 4414 is registered for TCP.

Is it safe to open port 4414?

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 4414 is open?

On Linux run "ss -ltnup 'sport = :4414'", on macOS "lsof -nP -i :4414", and on Windows "netstat -ano | findstr :4414" to see the local process. From another machine, "nmap -p 4414 <host>" shows whether it is reachable.
