Description: The Joomla ACL (Access Control List) is a system that manages user permissions and access levels. This mechanism allows administrators to define who can view, edit, or manage different parts of a website’s content and functionalities. The ACL is based on the assignment of user groups and access levels, providing great flexibility in permission management. For example, groups such as ‘Administrators’, ‘Editors’, and ‘Subscribers’ can be created, each with different privileges. This is especially useful in websites with multiple collaborators, where maintaining the security and integrity of content is crucial. Joomla’s ACL applies not only to registered users but can also be configured for unauthenticated visitors, allowing for more granular control over who can access specific content. Additionally, Joomla’s interface makes it easy to configure these rules, enabling administrators to adjust permissions intuitively. In summary, Joomla’s ACL is an essential tool for user management and security on the platform, ensuring that each user has access only to what they need to perform their tasks.
