01 Security

Is port 1468 dangerous?

We have no specific security note for port 1468. 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 1468, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1468'      # process listening on 1468
sudo lsof -nP -i :1468

macOS

sudo lsof -nP -i :1468

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1468 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1468
netstat -ano | findstr :1468

From another machine

nmap -p 1468 -sV <host>
sudo nmap -sU -p 1468 <host>
nc -zv <host> 1468

Block it in the firewall

sudo ufw deny 1468/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 1468" -Direction Inbound -LocalPort 1468 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 1468 used for?

Port 1468 is assigned by IANA to csdm (CSDM).

Is port 1468 TCP or UDP?

Port 1468 is registered for TCP and UDP.

Is it safe to open port 1468?

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 1468 is open?

On Linux run "ss -ltnup 'sport = :1468'", on macOS "lsof -nP -i :1468", and on Windows "netstat -ano | findstr :1468" to see the local process. From another machine, "nmap -p 1468 <host>" shows whether it is reachable.
