01 Security

Is port 462 dangerous?

We have no specific security note for port 462. 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 462, and is it reachable?

Linux

sudo ss -ltnup 'sport = :462'      # process listening on 462
sudo lsof -nP -i :462

macOS

sudo lsof -nP -i :462

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 462 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 462
netstat -ano | findstr :462

From another machine

nmap -p 462 -sV <host>
sudo nmap -sU -p 462 <host>
nc -zv <host> 462

Block it in the firewall

sudo ufw deny 462/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 462" -Direction Inbound -LocalPort 462 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 462 used for?

Port 462 is assigned by IANA to datasurfsrvsec (DataRampSrvSec).

Is port 462 TCP or UDP?

Port 462 is registered for TCP and UDP.

Is it safe to open port 462?

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 462 is open?

On Linux run "ss -ltnup 'sport = :462'", on macOS "lsof -nP -i :462", and on Windows "netstat -ano | findstr :462" to see the local process. From another machine, "nmap -p 462 <host>" shows whether it is reachable.
