01 Security

Is port 5084 dangerous?

We have no specific security note for port 5084. 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 5084, and is it reachable?

Linux

sudo ss -ltnup 'sport = :5084'      # process listening on 5084
sudo lsof -nP -i :5084

macOS

sudo lsof -nP -i :5084

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 5084 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 5084
netstat -ano | findstr :5084

From another machine

nmap -p 5084 -sV <host>
sudo nmap -sU -p 5084 <host>
nc -zv <host> 5084

Block it in the firewall

sudo ufw deny 5084/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 5084" -Direction Inbound -LocalPort 5084 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 5084 used for?

Port 5084 is assigned by IANA to llrp (EPCglobal Low-Level Reader Protocol).

Is port 5084 TCP or UDP?

Port 5084 is registered for TCP and UDP.

Is it safe to open port 5084?

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 5084 is open?

On Linux run "ss -ltnup 'sport = :5084'", on macOS "lsof -nP -i :5084", and on Windows "netstat -ano | findstr :5084" to see the local process. From another machine, "nmap -p 5084 <host>" shows whether it is reachable.
