This image depicts the WebCenter Portal security model. At the top is a section labeled Users and Groups, with a box labeled Identity Store that contains a lock icon, a user, and groups. Outside the box are other users labeled Unregistered Users and an unlock icon. Below the users and groups is a section labeled WebCenter Portal Permissions. This box includes two checklists labeled Application Roles and Portal Roles, representing that application roles are separate from portal roles. Under the WebCenter Portal Permissions section is a section labeled Secure WebCenter Portal Objects. It includes representations of portals, portal hierarchies, the Home portal, pages, portlets and task flows, files and folders, and a list of resources (page styles, page templates, skins, navigations, resource catalogs, data controls, and mashup styles).
