Make certain pages available to logged-in users only I need some help and here is the issue:

I am building a site using Drupal 7.

I need to make certain pages only visible to logged-in users (each having their own username/password), other users should be simply redirected or shown an error message. Is this functionality maybe included in Drupal 7 itself or is there a module that does this (something simpler than Organic Groups)?
You need to use Content Access module for fine grained node view permissions.


  This module allows you to manage permissions for content types by role
  and author. It allows you to specifiy custom view, edit and delete
  permissions for each content type. Optionally you can enable per
  content access settings, so you can customize the access for each
  content node.
