01 Security

Is port 3097 dangerous?

We have no specific security note for port 3097. 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 3097, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3097'      # process listening on 3097
sudo lsof -nP -i :3097

macOS

sudo lsof -nP -i :3097

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3097 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3097
netstat -ano | findstr :3097

From another machine

nmap -p 3097 -sV <host>
nc -zv <host> 3097

Block it in the firewall

sudo ufw deny 3097/sctp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 3097" -Direction Inbound -LocalPort 3097 -Protocol SCTP -Action Block  # Windows
04 FAQ
What is port 3097 used for?

Port 3097 is assigned by IANA to itu-bicc-stc (ITU-T Q.1902.1/Q.2150.3).

Is port 3097 TCP or UDP?

Port 3097 is registered for SCTP.

Is it safe to open port 3097?

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 3097 is open?

On Linux run "ss -ltnup 'sport = :3097'", on macOS "lsof -nP -i :3097", and on Windows "netstat -ano | findstr :3097" to see the local process. From another machine, "nmap -p 3097 <host>" shows whether it is reachable.
