When I run any of the firewall checks available online, I get the response that the main ports are hidden/invisible/stealthed but that lots of other ports are merely closed, ie they are not communicating with anyone at the moment, but they are visible and could be used by an intruder under the right circumstances. How do I hide them all? Is that possible?
Does it matter that they are closed and not hidden. I'm a beginner at all this!
