Ah, the ol' 'security through obscurity' with option D. I'll stick to the proven method of C, thanks.

I personally think using portknocking to protect ssh access for root is the best option.

Disabling SSH altogether? B? No way, that's way too restrictive. Gotta go with C on this one.

I agree with Shawnee, disabling ssh access for root is a good security measure.

Renaming root? That's just asking for trouble. I'd go with C - simple and effective.

Option C seems like the way to go. Disabling root access is a pretty standard security practice.
