Which program uses port 5002, and is it reachable?
Linux
sudo ss -ltnup 'sport = :5002' # process listening on 5002
sudo lsof -nP -i :5002macOS
sudo lsof -nP -i :5002
Windows (PowerShell)

From another machine
nmap -p 5002 -sV <host> sudo nmap -sU -p 5002 <host> nc -zv <host> 5002
Block it in the firewall

What is port 5002 used for?

Is it safe to open port 5002?
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. Require authentication on cameras and media servers.
How do I check if port 5002 is open?
On Linux run "ss -ltnup 'sport = :5002'", on macOS "lsof -nP -i :5002", and on Windows "netstat -ano | findstr :5002" to see the local process. From another machine, "nmap -p 5002 <host>" shows whether it is reachable.
