Is port 485 dangerous?

We have no specific security note for port 485. 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 485, and is it reachable?

Linux

sudo ss -ltnup 'sport = :485'      # process listening on 485
sudo lsof -nP -i :485

macOS

sudo lsof -nP -i :485

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 485 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 485
netstat -ano | findstr :485

From another machine

nmap -p 485 -sV <host>
sudo nmap -sU -p 485 <host>
nc -zv <host> 485

Block it in the firewall

sudo ufw deny 485/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 485" -Direction Inbound -LocalPort 485 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 485 used for?

Port 485 is assigned by IANA to powerburst (Air Soft Power Burst).

Is port 485 TCP or UDP?

Port 485 is registered for TCP and UDP.

Is it safe to open port 485?

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 485 is open?

On Linux run "ss -ltnup 'sport = :485'", on macOS "lsof -nP -i :485", and on Windows "netstat -ano | findstr :485" to see the local process. From another machine, "nmap -p 485 <host>" shows whether it is reachable.
