Is port 3263 dangerous?

We have no specific security note for port 3263. 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 3263, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3263'      # process listening on 3263
sudo lsof -nP -i :3263

macOS

sudo lsof -nP -i :3263

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3263 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3263
netstat -ano | findstr :3263

From another machine

nmap -p 3263 -sV <host>
sudo nmap -sU -p 3263 <host>
nc -zv <host> 3263

Block it in the firewall

sudo ufw deny 3263/tcp                                         # Linux (ufw)

What is port 3263 used for?

Port 3263 is assigned by IANA to ecolor-imager (E-Color Enterprise Imager).

Is port 3263 TCP or UDP?

Port 3263 is registered for TCP and UDP.

Is it safe to open port 3263?

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 3263 is open?

On Linux run "ss -ltnup 'sport = :3263'", on macOS "lsof -nP -i :3263", and on Windows "netstat -ano | findstr :3263" to see the local process. From another machine, "nmap -p 3263 <host>" shows whether it is reachable.
