- 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
nmap -p 6315 -sV <host> sudo nmap -sU -p 6315 <host> nc -zv <host> 6315

What is port 6315 used for?
Port 6315 is assigned by IANA to scup (Sensor Control Unit Protocol), scup-disc (Sensor Control Unit Protocol Discovery Protocol).
Is port 6315 TCP or UDP?
Port 6315 is registered for TCP and UDP.
Is it safe to open port 6315?
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 6315 is open?
On Linux run "ss -ltnup 'sport = :6315'", on macOS "lsof -nP -i :6315", and on Windows "netstat -ano | findstr :6315" to see the local process. From another machine, "nmap -p 6315 <host>" shows whether it is reachable.
