Is port 3416 dangerous?

We have no specific security note for port 3416. 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.

Get-NetUDPEndpoint -LocalPort 3416
netstat -ano | findstr :3416

From another machine

nmap -p 3416 -sV <host>
sudo nmap -sU -p 3416 <host>
nc -zv <host> 3416

Block it in the firewall
