Is port 1394 dangerous?

We have no specific security note for port 1394. Its risk depends on the program actually listening on it. General advice for monitoring & logging services:

  • Restrict management and monitoring protocols to the monitoring network.
  • Replace community strings and default credentials.
  • Send logs over TLS.

03 Check it

Which program uses port 1394, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1394'      # process listening on 1394
sudo lsof -nP -i :1394

macOS

sudo lsof -nP -i :1394

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1394 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1394
netstat -ano | findstr :1394

From another machine

nmap -p 1394 -sV <host>
sudo nmap -sU -p 1394 <host>
nc -zv <host> 1394

Block it in the firewall

sudo ufw deny 1394/tcp                                         # Linux (ufw)

Is port 1394 TCP or UDP?

Port 1394 is registered for TCP and UDP.

Is it safe to open port 1394?

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. Restrict management and monitoring protocols to the monitoring network.

How do I check if port 1394 is open?

On Linux run "ss -ltnup 'sport = :1394'", on macOS "lsof -nP -i :1394", and on Windows "netstat -ano | findstr :1394" to see the local process. From another machine, "nmap -p 1394 <host>" shows whether it is reachable.
