Is port 45824 dangerous?

We have no specific security note for port 45824. 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.

Is port 45824 TCP or UDP?

Port 45824 is registered for TCP.

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 45824 is open?

On Linux run "ss -ltnup 'sport = :45824'", on macOS "lsof -nP -i :45824", and on Windows "netstat -ano | findstr :45824" to see the local process. From another machine, "nmap -p 45824 <host>" shows whether it is reachable.
