- 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.

From another machine

What is port 4070 used for?

Is port 4070 TCP or UDP?
Port 4070 is registered for TCP and UDP.
Is it safe to open port 4070?
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 4070 is open?
On Linux run "ss -ltnup 'sport = :4070'", on macOS "lsof -nP -i :4070", and on Windows "netstat -ano | findstr :4070" to see the local process. From another machine, "nmap -p 4070 <host>" shows whether it is reachable.
