Episode 9 — Master Network Technology Concepts: Wireless, SDN, WAN, and Virtualization (Task 5)

This episode covers modern network technology concepts that commonly appear in exam questions because they change how controls, visibility, and attack paths work. You will define wireless security considerations, software-defined networking principles, WAN connectivity realities, and how virtualization shifts trust boundaries and monitoring placement. We will connect these technologies to risks such as misconfigured wireless authentication, SDN policy errors, overlay network blind spots, and WAN dependencies that affect resilience during containment. You will also learn how to reason about evidence, including where logs live, what telemetry is trustworthy, and how to validate that a policy is enforced across dynamic infrastructure. Practical examples will show how attackers exploit complexity, and how defenders simplify decision-making by focusing on identity, segmentation intent, and verified enforcement.
