Is port 8793 dangerous?

We have no specific security note for port 8793. 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 8793, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8793'      # process listening on 8793
sudo lsof -nP -i :8793

macOS

sudo lsof -nP -i :8793

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8793 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8793
netstat -ano | findstr :8793

From another machine

nmap -p 8793 -sV <host>
sudo nmap -sU -p 8793 <host>
nc -zv <host> 8793

Block it in the firewall

sudo ufw deny 8793/tcp                                         # Linux (ufw)

04 FAQ
What is port 8793 used for?

Port 8793 is assigned by IANA to acd-pm (Accedian Performance Measurement).

Is port 8793 TCP or UDP?

Port 8793 is registered for TCP and UDP.

Is it safe to open port 8793?

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 8793 is open?

On Linux run "ss -ltnup 'sport = :8793'", on macOS "lsof -nP -i :8793", and on Windows "netstat -ano | findstr :8793" to see the local process. From another machine, "nmap -p 8793 <host>" shows whether it is reachable.
