01 Security

Is port 23002 dangerous?

We have no specific security note for port 23002. 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 23002, and is it reachable?

Linux

sudo ss -ltnup 'sport = :23002'      # process listening on 23002
sudo lsof -nP -i :23002

macOS

sudo lsof -nP -i :23002

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 23002 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 23002
netstat -ano | findstr :23002

From another machine

nmap -p 23002 -sV <host>
sudo nmap -sU -p 23002 <host>
nc -zv <host> 23002

Block it in the firewall

sudo ufw deny 23002/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 23002" -Direction Inbound -LocalPort 23002 -Protocol TCP -Action Block  # Windows

What is port 23002 used for?

Port 23002 is assigned by IANA to inovaport3 (Inova LightLink Server Type 3).

Is port 23002 TCP or UDP?

Port 23002 is registered for TCP and UDP.

Is it safe to open port 23002?

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 23002 is open?

On Linux run "ss -ltnup 'sport = :23002'", on macOS "lsof -nP -i :23002", and on Windows "netstat -ano | findstr :23002" to see the local process. From another machine, "nmap -p 23002 <host>" shows whether it is reachable.
