01 Security

Is port 38412 dangerous?

We have no specific security note for port 38412. 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 38412, and is it reachable?

Linux

sudo ss -ltnup 'sport = :38412'      # process listening on 38412
sudo lsof -nP -i :38412

macOS

sudo lsof -nP -i :38412

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 38412 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 38412
netstat -ano | findstr :38412

From another machine

nmap -p 38412 -sV <host>
nc -zv <host> 38412

Block it in the firewall

sudo ufw deny 38412/sctp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 38412" -Direction Inbound -LocalPort 38412 -Protocol SCTP -Action Block  # Windows
04 FAQ
What is port 38412 used for?

Port 38412 is assigned by IANA to ng-control (NG Control Plane (3GPP)).

Is port 38412 TCP or UDP?

Port 38412 is registered for SCTP.

Is it safe to open port 38412?

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 38412 is open?

On Linux run "ss -ltnup 'sport = :38412'", on macOS "lsof -nP -i :38412", and on Windows "netstat -ano | findstr :38412" to see the local process. From another machine, "nmap -p 38412 <host>" shows whether it is reachable.
