What do 'Security Settings' control in a Mendix application?

In a Mendix application, 'Security Settings' are essential for managing how users interact with the application, specifically focusing on user roles, access rights, and permissions. This functionality allows developers to define different levels of access to various parts of the application based on the roles assigned to users. For example, an application might allow administrators to have full control over all entities while limiting regular users to only view certain data or perform specific actions.

Understanding user roles and permissions is crucial for ensuring that sensitive data is protected and that users can only access what is appropriate for their role within the application. This capability supports the security and integrity of the data within the application and ensures compliance with data protection regulations.

In contrast, the other options relate to aspects of the application that do not pertain directly to user access and security management. For instance, user interface themes and styles focus on the aesthetic elements of the application, while network connections and data storage pertain to infrastructure and backend configurations. Debugging options and performance metrics involve monitoring and optimizing application performance rather than controlling user interactions. Thus, the focus of 'Security Settings' is distinctly on user access control, making it pivotal for application security management.
