Is port 2163 dangerous?

We have no specific security note for port 2163. 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 2163, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2163'      # process listening on 2163
sudo lsof -nP -i :2163

macOS

sudo lsof -nP -i :2163

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2163 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2163
netstat -ano | findstr :2163

From another machine

nmap -p 2163 -sV <host>
sudo nmap -sU -p 2163 <host>
nc -zv <host> 2163

Block it in the firewall

sudo ufw deny 2163/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2163" -Direction Inbound -LocalPort 2163 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2163 used for?

Port 2163 is assigned by IANA to navisphere-sec (Navisphere Secure).

Is port 2163 TCP or UDP?

Port 2163 is registered for TCP and UDP.

Is it safe to open port 2163?

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 2163 is open?

On Linux run "ss -ltnup 'sport = :2163'", on macOS "lsof -nP -i :2163", and on Windows "netstat -ano | findstr :2163" to see the local process. From another machine, "nmap -p 2163 <host>" shows whether it is reachable.
