Just login as root with ssh keys?

If you needed to somehow block brute force cracking attacks against
the root account either globally disable password auth, or it appears
you can use the option "PermitRootLogin without-password" to restrict
remote root logins via SSH to keys only. I haven't tried this option
myself.
