Comments Not Allowed unless logged in

I am new to your blog engine and liking it very much.  Don't know if this has been covered or not.
I am setting up a blog on my intranet inside of our network.  I have been playing with a few things and noticed that I can post a comment on a post even though I don't have a user account.  Is there an easy fix to only allow comments if the person is logged in?
