To display content only to those users who have a specified level of security permissions, you can use a Security Trim Control. Specify one or more permission levels in the Behavior section of this control's properties. You can set it to many common permission levels, including the option to show content to no one but contributing site authors or site administrators. Then, insert the component on your page and place any content - including other SharePoint components - inside of it.
