Episode 4 — CIA and AAA: The Core Security Models (1.1)
This episode covers two foundational security models that appear throughout Security+: CIA and AAA. Confidentiality protects information from unauthorized access, integrity protects information from unauthorized or improper change, and availability ensures systems and data remain usable when needed. Authentication verifies identity, authorization determines what that identity is allowed to do, and accounting records activity for accountability, auditing, and investigation. For exam scenarios, students should connect these models to access control, logging, identity systems, system design, and incident response, such as identifying whether a data leak, altered record, or service outage is the main security concern.
