01 Security

Is port 8002 dangerous?

We have no specific security note for port 8002. 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 8002, and is it reachable?

Linux

sudo ss -ltnup 'sport = :8002'      # process listening on 8002
sudo lsof -nP -i :8002

macOS

sudo lsof -nP -i :8002

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 8002 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 8002
netstat -ano | findstr :8002

From another machine

nmap -p 8002 -sV <host>
sudo nmap -sU -p 8002 <host>
nc -zv <host> 8002

Block it in the firewall

sudo ufw deny 8002/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 8002" -Direction Inbound -LocalPort 8002 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 8002 used for?

Port 8002 is assigned by IANA to teradataordbms (Teradata ORDBMS).

Is port 8002 TCP or UDP?

Port 8002 is registered for TCP and UDP.

Is it safe to open port 8002?

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 8002 is open?

On Linux run "ss -ltnup 'sport = :8002'", on macOS "lsof -nP -i :8002", and on Windows "netstat -ano | findstr :8002" to see the local process. From another machine, "nmap -p 8002 <host>" shows whether it is reachable.
