Well, by listening on more ports, you're just making yourself a more
appealing target. As such, I don't think you're really increasing your
security. It's attacks on the services that you're running which matter.

As for the concept of an automated attack-attempt tracking system, it
seems like a good idea. Maybe I'll look more at how it's done when I have
some free time.
