- 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.

Which program uses port 15002, and is it reachable?
Linux
sudo ss -ltnup 'sport = :15002' # process listening on 15002
sudo lsof -nP -i :15002macOS
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

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.
