01 Security

Is port 15002 dangerous?

We have no specific security note for port 15002. 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 15002, and is it reachable?

Linux

sudo ss -ltnup 'sport = :15002'      # process listening on 15002
sudo lsof -nP -i :15002

macOS

sudo lsof -nP -i :15002

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 15002 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 15002
netstat -ano | findstr :15002

From another machine

nmap -p 15002 -sV <host>
nc -zv <host> 15002

Block it in the firewall

sudo ufw deny 15002/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 15002" -Direction Inbound -LocalPort 15002 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 15002 used for?

Port 15002 is assigned by IANA to onep-tls (Open Network Environment TLS).

Is port 15002 TCP or UDP?

Port 15002 is registered for TCP.

Is it safe to open port 15002?

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 15002 is open?

On Linux run "ss -ltnup 'sport = :15002'", on macOS "lsof -nP -i :15002", and on Windows "netstat -ano | findstr :15002" to see the local process. From another machine, "nmap -p 15002 <host>" shows whether it is reachable.
