The three types of authorization are Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), and Mandatory Access Control (MAC). RBAC assigns permissions based on user roles. ABAC grants access based on user attributes and contextual conditions. MAC enforces access policies set by a central authority, limiting user discretion. Each type addresses different organizational needs and security requirements.
