Controlling information exposure
Oracle9iAS Portal gives you complete control over who can access the information in your portal.
Create pages for non-confidential information, and display those pages to everyone, even users who are not logged on to the portal.
Create other pages for confidential information and grant access to specific users or groups. Only users who are logged on to the portal and who have specific access to a page, either directly or through a group to which they belong, can view the content of these pages.
Within the same page, add tabs upon which to place content of a sensitive nature. You can control access to each tab within a page individually, so that a tab and its content are visible only if a user has the proper authorization.
Enable item level security on a page to allow content contributors to choose which users or groups can see individual items on that page.
Apply security at the portlet level to control which users can see individual portlets. If a user does not have the proper authorization on a particular portlet, the user will not see the portlet on any page to which it has been added.
