A. Users can modify their own access privileges
B. Users receive permissions based on their job roles
C. Users must be approved by multiple managers for access
D. Users authenticate only once using single sign-on (SSO)
E. Users receive temporary access by default
Answer
B. Users receive permissions based on their job roles
Explanation
RBAC grants permissions based on a user’s job function, minimizing unnecessary access.
Role-based access control (RBAC) follows the principle that users receive permissions based on their job roles.
RBAC is an access control model that assigns permissions to users according to their roles within an organization, rather than on an individual basis. A role represents a collection of permissions needed to perform specific job functions, such as administrator, HR specialist, or data analyst.
This approach ensures that users have access only to the resources necessary for their responsibilities, supporting the principle of least privilege and reducing the risk of unauthorized access or over-permissioned accounts.
When an employee’s job changes, their access can be easily modified by updating their assigned role, streamlining access management and maintaining security.
RBAC is widely adopted in organizations to simplify permission management, enhance data protection, and support regulatory compliance by ensuring that only authorized users can access sensitive information and systems.
RBAC assigns access rights according to organizational roles, ensuring users have only the permissions needed for their specific job functions, which enhances security and operational efficiency.
