Episode 50: Access Control Models Overview

Access control is foundational to every security program, and this episode introduces the core models used to govern who can access what, when, and under what conditions. We examine the primary access control models—Discretionary Access Control (DAC), Mandatory Access Control (MAC), Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), and Rule-Based Access Control—and explain where each is most effectively applied in the enterprise. You’ll learn how these models impact system design, auditability, and compliance outcomes.

For CISOs, selecting and implementing the right access model is about more than just security—it’s about usability, scalability, and policy alignment. This episode also discusses how access control ties into identity governance, privilege management, and zero trust principles. The CCISO exam may test your ability to evaluate model selection scenarios or address complex access requirements in a dynamic organization. With this episode, you’ll gain the executive-level understanding needed to make strategic decisions about identity and access governance.
