Once a user’s identity is authenticated, the system must decide what they are allowed to do. This episode focuses on common authorization models: Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), Mandatory Access Control (MAC), and Discretionary Access Control (DAC). We explore the rules and policies that govern each model, along with their strengths, weaknesses, and appropriate use cases. You'll learn how to align authorization mechanisms with security policies and compliance requirements. For the CISSP exam and real-world implementation, these models form the core of secure resource management.
