Login Security Joomla provides anonymous access for everyone and basic login security for registered users. Three types of users are classified: Unregistered users Visitors who haven’t logged in Registered front-end users Readers who log in to gain access to restrict content Registered back-end users Users who are granted permissions for making changes to the site 05-412-421: Information Retrieval Administering Joomla!

Login Security: Registered Front-End Users Contains 4 groups of privileged users: Registered: Can read restricted content (if available), but can not submit new content articles Author: Can post and modify their own articles, even determine when the article will be published (under administrator’s setting) Editor: Like an author, + edit other contributors’ content Publisher: Like an Publisher + publish or unpublish content on the site 05-412-421: Information Retrieval Administering Joomla!

Login Security: Registered Back-End Users contain 4 groups of administrative users of the site. Manager: Lowest authority, limited access to the admin Control Panel can confirm registration for users perform basic maintenance, e.g. categorizing an article or managing sections and categories Administrator: install and uninstall extensions to the system, change the selected template & the layout of a page modify the permissions of any user lower than their access level 05-412-421: Information Retrieval Administering Joomla!

Login Security: Registered Back-End Users (cont.) Super-administrator (SA): SA is the one who created during the initial Joomla installation, under the account name “admin” Act as the king of the web site, therefore having no restrictions on the system Similar to “root” of Linux Depending on the user’s group designation, the administrator interface will appear differently Ex: The interfaces for the lower-level groups (e.g. manager) are missing many of the buttons and menu items that are present when an SA is logged into the system 05-412-421: Information Retrieval Administering Joomla!

Menu Manager Menu is a channel (or access point) to connect to every piece of content that is accessible through the Joomla system We have used them already in the previous chapter when making links to the newly created contents 05-412-421: Information Retrieval Administering Joomla!

Menu Manager (cont.) Q: How could we know what sort of users can access (or see) this particular menu? 05-412-421: Information Retrieval Administering Joomla!
