Which aspect of security does role-based access control primarily focus on?

Role-based access control (RBAC) primarily focuses on ensuring authorized access to sensitive data by assigning permissions and access rights based on the roles of individual users within an organization. This framework allows system administrators to define roles that encapsulate a set of permissions aligned with job responsibilities, ensuring that users can only access the information and resources necessary for their specific tasks. By restricting access in this manner, RBAC helps to protect sensitive data from unauthorized users, thereby enhancing overall security.

This approach not only secures data but also simplifies management; as users change roles or leave an organization, their permissions can be adjusted or revoked in line with their current role. In this way, RBAC serves as a critical component for maintaining data integrity and confidentiality within various systems.
