01 Security

Is port 36462 dangerous?

We have no specific security note for port 36462. 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 36462, and is it reachable?

Linux

sudo ss -ltnup 'sport = :36462'      # process listening on 36462
sudo lsof -nP -i :36462

macOS

sudo lsof -nP -i :36462

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 36462 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 36462
netstat -ano | findstr :36462

From another machine

nmap -p 36462 -sV <host>
nc -zv <host> 36462

Block it in the firewall

sudo ufw deny 36462/sctp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 36462" -Direction Inbound -LocalPort 36462 -Protocol SCTP -Action Block  # Windows
04 FAQ
What is port 36462 used for?

Port 36462 is assigned by IANA to xw-control (Xw-Control Plane (3GPP)).

Is port 36462 TCP or UDP?

Port 36462 is registered for SCTP.

Is it safe to open port 36462?

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 36462 is open?

On Linux run "ss -ltnup 'sport = :36462'", on macOS "lsof -nP -i :36462", and on Windows "netstat -ano | findstr :36462" to see the local process. From another machine, "nmap -p 36462 <host>" shows whether it is reachable.
