According to RBAC best practices, what should be prioritized when configuring roles?

Prioritizing modularity and cumulative effects on user permissions when configuring roles aligns well with role-based access control (RBAC) best practices. This approach ensures that roles can be built in a way that allows for scalability and makes it easier to manage access rights effectively.

Modularity allows for distinct roles to be created based on specific functions or tasks within the organization. By segmenting permissions into smaller, manageable components, you can ensure that users only have the access necessary for their current responsibilities. This reduces the risk of over-privileging users and helps maintain security by limiting the number of permissions assigned to any individual role.

Additionally, understanding the cumulative effects on user permissions is critical. As users may hold multiple roles or permissions, careful consideration must be given to how these permissions interact with one another to avoid conflicts or unintended access. This aspect of RBAC helps in defining clear boundaries and ensuring that user permissions align with organizational policies.

In contrast, while flexibility, simplicity, and consistency are important considerations in RBAC design, they do not capture the essential need for a modular approach that addresses user permissions comprehensively and systematically. Flexibility may introduce complexity that could lead to errors, simplicity in design might overlook critical security aspects, and consistency, while valuable, does
