provides Category & Pages protection on a roles & user basis.

Role Scoper is a comprehensive access control solution, giving you CMS-like control of reading and editing permissions. Assign restrictions and roles to specific pages, posts or categories

With the "User Access Manager"-plugin you can manage the access to your posts, pages and files. You only create a user group, put registered users to this and set up the rights for this group. From now on the post/page is only accessible and writable for the specified group. This plugin is useful if you need a member area or a private section at your blog or you want that other people can write at your blog but not everywhere.

This wordpress plugin will allow you to restrict all, none, or certain pages to logged in users only.
