01 Security

Is port 578 dangerous?

We have no specific security note for port 578. 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 578, and is it reachable?

Linux

sudo ss -ltnup 'sport = :578'      # process listening on 578
sudo lsof -nP -i :578

macOS

sudo lsof -nP -i :578

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 578 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 578
netstat -ano | findstr :578

From another machine

nmap -p 578 -sV <host>
sudo nmap -sU -p 578 <host>
nc -zv <host> 578

Block it in the firewall

sudo ufw deny 578/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 578" -Direction Inbound -LocalPort 578 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 578 used for?

Port 578 is assigned by IANA to ipdd (ipdd).

Is port 578 TCP or UDP?

Port 578 is registered for TCP and UDP.

Is it safe to open port 578?

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 578 is open?

On Linux run "ss -ltnup 'sport = :578'", on macOS "lsof -nP -i :578", and on Windows "netstat -ano | findstr :578" to see the local process. From another machine, "nmap -p 578 <host>" shows whether it is reachable.
