What is the main advantage of Role-Based Access Control (RBAC)?

1. Access is granted based purely on user identity

2. Users can gain rights explicitly defined by their roles

3. Access is determined by user roles, simplifying permission management

4. It eliminates the need for any group definitions

The correct answer is: Access is determined by user roles, simplifying permission management

The main advantage of Role-Based Access Control (RBAC) is that access is determined by user roles, which simplifies permission management. In an RBAC system, administrators assign permissions to specific roles within the organization rather than to each user individually. This hierarchical approach means that when users are assigned to roles, they inherently receive the permissions associated with those roles. As a result, managing user access becomes more efficient, as changes to permissions can be made at the role level rather than needing to be adjusted for each individual user. This structure enhances security and reduces the chances of human error in permission assignments, as users only receive permissions aligned with their job functions. Furthermore, it provides a clear overview of who has access to what resources by simply looking at the roles defined within the system, making it easier to audit permissions and ensure compliance with security policies.
