Is port 1283 dangerous?

We have no specific security note for port 1283. 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 1283, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1283'      # process listening on 1283
sudo lsof -nP -i :1283

macOS

sudo lsof -nP -i :1283

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1283 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1283
netstat -ano | findstr :1283

From another machine

nmap -p 1283 -sV <host>
sudo nmap -sU -p 1283 <host>
nc -zv <host> 1283

Block it in the firewall

sudo ufw deny 1283/tcp                                         # Linux (ufw)

What is port 1283 used for?

Port 1283 is assigned by IANA to productinfo (Product Information).

Is port 1283 TCP or UDP?

Port 1283 is registered for TCP and UDP.

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 1283 is open?

On Linux run "ss -ltnup 'sport = :1283'", on macOS "lsof -nP -i :1283", and on Windows "netstat -ano | findstr :1283" to see the local process. From another machine, "nmap -p 1283 <host>" shows whether it is reachable.
