Certified: The CISSP Audio Course ·

2025/06/23

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

Episode 72: Identity Proofing and Registration Processes

Certified: The CISSP Audio Course ·

2025/06/23

Before you can authenticate someone, you must first establish their identity through a process called identity proofing. In this episode, we cover how identity proofing works—from in-person validation and biometric capture to document verification and knowledge-based authentication.
