This is true, however, people with SA rights is not limited solely to the
SA account as your post implies. This fault also includes anybody with
administrator access to SQL, if you are using windows authentication. So
if your box has been rooted in some other way you can be vulerable to this
as a additional attack. So if you start out with a secure (for microsoft)
box to begin with before installing your server you will be much better
off. Of course as you correctly point out there are all too many lazy
admins out there that dont take the time to do this.
