In SharePoint 2010, access is controlled through a role-based system that uses permission levels. Permission levels specify what permissions users have on a SharePoint site. These permissions determine the specific actions that users can perform on the site; in essence, each permission level is a collection of permissions. SharePoint Foundation has five default permission levels:
- Read – This permission level gives you read-only access to the website.
- Contribute – In addition to all the permissions included in the Read permission level, the Contribute permission level allows you to create and edit items in existing lists and document libraries
- Design – In addition to all the permissions included in the Contribute permission level, the Design permission level allows you to create lists and document libraries, approve items, and edit pages
- Full Control – This permission level gives you full control.
