Is port 8908 dangerous?

We have no specific security note for port 8908. 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 8908, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8908'      # process listening on 8908
sudo lsof -nP -i :8908

macOS

sudo lsof -nP -i :8908

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8908 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8908
netstat -ano | findstr :8908

From another machine

nmap -p 8908 -sV <host>
nc -zv <host> 8908

Block it in the firewall

sudo ufw deny 8908/tcp                                         # Linux (ufw)

04 FAQ
What is port 8908 used for?

Port 8908 is assigned by IANA to dpp (WFA Device Provisioning Protocol).

Is port 8908 TCP or UDP?

Port 8908 is registered for TCP.

Is it safe to open port 8908?

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 8908 is open?

On Linux run "ss -ltnup 'sport = :8908'", on macOS "lsof -nP -i :8908", and on Windows "netstat -ano | findstr :8908" to see the local process. From another machine, "nmap -p 8908 <host>" shows whether it is reachable.
