Detecting intruders
-
Is there any way to detect intruders and find out what they have been up to?
I see a lot of failed passwords and invalid users when looking at my system logs.
I'm not sure how to tell what is visible from the outside world.

uhm?
by default pfSense doesn't allow logins from the wan side… you shouldn't allow it either.

Look at your firewall rules on the WAN tab. That's what is visible to the outside world.
