Restricting access to certain content

While experimenting with the People content-type, I noticed that everyone could view the record. That's not what I want. I only want authenticated users viewing People. Otherwise I can't expect users to be open and honest. We have to protect that information from un-vetted eyes. This is why we have the invitation-based, and physically authenticated approach to user accounts.

IN order to lock things down the way we want, we needed to install a new module, Content Access. Installing new modules is more streamlined in Drupal 7, I don't have to upload and uncompress/unzip the file anymore, I just pass it into a form and it does the rest.
