01 Security

Is port 5574 dangerous?

We have no specific security note for port 5574. 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 5574, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5574'      # process listening on 5574
sudo lsof -nP -i :5574

macOS

sudo lsof -nP -i :5574

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5574 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5574
netstat -ano | findstr :5574

From another machine

nmap -p 5574 -sV <host>
nc -zv <host> 5574

Block it in the firewall

sudo ufw deny 5574/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5574" -Direction Inbound -LocalPort 5574 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5574 used for?

Port 5574 is assigned by IANA to lsi-bobcat (SAS IO Forwarding).

Is port 5574 TCP or UDP?

Port 5574 is registered for TCP.

Is it safe to open port 5574?

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 5574 is open?

On Linux run "ss -ltnup 'sport = :5574'", on macOS "lsof -nP -i :5574", and on Windows "netstat -ano | findstr :5574" to see the local process. From another machine, "nmap -p 5574 <host>" shows whether it is reachable.
