01 Security

Is port 1408 dangerous?

We have no specific security note for port 1408. 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 1408, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1408'      # process listening on 1408
sudo lsof -nP -i :1408

macOS

sudo lsof -nP -i :1408

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1408 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1408
netstat -ano | findstr :1408

From another machine

nmap -p 1408 -sV <host>
sudo nmap -sU -p 1408 <host>
nc -zv <host> 1408

Block it in the firewall

sudo ufw deny 1408/tcp                                         # Linux (ufw)

On Linux run "ss -ltnup 'sport = :1408'", on macOS "lsof -nP -i :1408", and on Windows "netstat -ano | findstr :1408" to see the local process. From another machine, "nmap -p 1408 <host>" shows whether it is reachable.
