This is getting at what I was trying to understand - 
This raises another question. A constant suggestion I've read is to block root 
logins and use sudo. If someone breaks in using my login/pw combo, what's to 
prevent them from using sudo to get root privileges? If they've hacked my 
username/password, then wouldn't sudo be the first thing they'd try, too?
