01 Security

Is port 482 dangerous?

We have no specific security note for port 482. 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 482, and is it reachable?

Linux

sudo ss -ltnup 'sport = :482'      # process listening on 482
sudo lsof -nP -i :482

macOS

sudo lsof -nP -i :482

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 482 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 482
netstat -ano | findstr :482

From another machine

nmap -p 482 -sV <host>
sudo nmap -sU -p 482 <host>
nc -zv <host> 482

Block it in the firewall

sudo ufw deny 482/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 482" -Direction Inbound -LocalPort 482 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 482 used for?

Port 482 is assigned by IANA to bgs-nsi (bgs-nsi).

Is port 482 TCP or UDP?

Port 482 is registered for TCP and UDP.

Is it safe to open port 482?

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 482 is open?

On Linux run "ss -ltnup 'sport = :482'", on macOS "lsof -nP -i :482", and on Windows "netstat -ano | findstr :482" to see the local process. From another machine, "nmap -p 482 <host>" shows whether it is reachable.
