[LOTR] Why are there no guards posted outside the entrance of Mt. Doom?

I feel as though Sauron, being as determined to survive as he was would put some sort of heavy fortifications or even guards around Mt. Doom so as not to allow anyone to enter. I'm sure as the creator of the ring he would know that someone would attrmpt to destroy it by tossing it into the fire. Or is he just that careless?

It simply never occurred to Sauron that they would attempt to destroy the ring.

The ring, for all the ill it does to its bearer, is still an artifact of great power, greatly expanding the power of anyone who manages to wear it and force it, even a little, to their will.  This makes it a very tempting tool.
