Security ======== Every page has its own permission tab, which is integrated like described in :doc:`../../cookbook/securing-your-application`. The permissions for the Sulu system in this tab has an influence on the UI of Sulu. The UI might also be adapted due to the permissions defined in Security Contexts. The form adapts to the permissions by changing its toolbar. The delete option in the edit dropdown is only available if the user has the delete permission on this page. The other toolbar items are only available if the user has the `edit` permission. The column navigation for the content is a bit more complicated. The entire tree is always visible, but the available functionality is changing based on the permissions of the page. The `delete` permission is tied to the delete item in the option dropdown. The `edit` permission is required to move and sort the page in the content tree. For sorting the page the `edit` permission of all siblings and the parent page is also required. For copying a page the user has to have the `view` permission on the source page. In addition to that the icon appearing on hovering one of the items in the content tree depends on its permission. If the user is allowed to edit the page a pencil shows up, in case the user has only the permission to view the page an eyes is shown instead. In case the user has no permission at all, there also will not appear any icon on hovering. In addition to the Sulu system the system of the webspace for this page is also shown on the permission tab, if the webspace has a system configured (see :doc:`../../book/webspaces` for more information on how to do this). If the webspace has configured the system with the `permission-check` flag set to `true`, Sulu will automatically check in this webspace if the current visitor is allowed to see the current page and only show pages in the navigation and smart content listings if the visitor has sufficient permissions.
