How to deny access to entire site for unauthenticated users?

What I'm trying to do:
1. Use Sitefinity to build internal applications that are password protected. Un-authenitcated users should only have to access the login page.

2. When a new page is created, have the permission to view the page be set to a role other than everyone. I know I can do this after creating the page but I don't like this approach because the applications contain very secure data and it is too easy (for me or others) to forget to change the permission after creating a page.

Question
 Is there a global security setting or a way to change the default permissions so that a page can only be viewed by administrators (or any role I choose) when first created.

To answer my own question. On the back office page that's used for creating pages, on the right is a link that says permissions for all pages.
