Manage permissions for a Web application (SharePoint Foundation 2010)
Published: May 12, 2010
A Web application is composed of an Internet Information Services (IIS) Web site that acts as a logical unit for the site collections that you create. Before you can create a site collection, you must create a Web application.
All Web applications have List, Site, and Personal permissions. Permissions for a Web application are comprehensive settings that apply to all users and groups for all site collections within a Web application. You can control user actions by enabling or disabling the associated permission on the Web application. For example, if you do not want users to be able to add pages to a Web site, you can disable the Add and Customize Pages permission that is one of the site-related permissions. For more information, see User permissions and permission levels (SharePoint Foundation 2010).
After you disable a specific permission for a Web application, the permission cannot be granted to any user of a site on the Web application.
If you want to set permissions for specific users or groups in a Web application, you can create a permission policy for the Web application. For more information, see Manage permission policies for a Web application (SharePoint Foundation 2010).
