What is Role-Based Access Control (RBAC)?

Role-Based Access Control (RBAC) is a highly structured access control model that is determined by the roles assigned to users within an organization. In this system, permissions to access resources are granted based on the user's role rather than on individual user identities. This approach streamlines the process of managing access rights and enhances security.

For example, a user assigned the role of "manager" might have access to sensitive data and administrative functions that are not available to someone in an "employee" role. This model ensures that individuals can only access information and perform actions necessary for their job functions, minimizing the risk of unauthorized access and potential data breaches.

Roles can be tailored to reflect an organization’s structure and are beneficial in large environments where managing individual user permissions would be impractical. In contrast to the other options, which focus on different methods or criteria for access control, RBAC specifically organizes access around defined roles to optimize security and efficiency in access management.
