Is port 6408 dangerous?

We have no specific security note for port 6408. 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 6408, and is it reachable?

Linux

sudo ss -ltnup 'sport = :6408'      # process listening on 6408
sudo lsof -nP -i :6408

macOS

sudo lsof -nP -i :6408

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 6408 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 6408
netstat -ano | findstr :6408

From another machine

nmap -p 6408 -sV <host>
nc -zv <host> 6408

Block it in the firewall

sudo ufw deny 6408/tcp                                         # Linux (ufw)

04 FAQ
What is port 6408 used for?

Port 6408 is assigned by IANA to boe-resssvr2 (Business Objects Enterprise internal server).

Is port 6408 TCP or UDP?

Port 6408 has no registered transport. Any program can still use it over TCP or UDP.

Is it safe to open port 6408?

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 6408 is open?

On Linux run "ss -ltnup 'sport = :6408'", on macOS "lsof -nP -i :6408", and on Windows "netstat -ano | findstr :6408" to see the local process. From another machine, "nmap -p 6408 <host>" shows whether it is reachable.
