Episode 4 — Build Cloud Networking Intuition for Security: Virtual Networks, Routing, and DNS (Task 5)
This episode explains cloud networking concepts the way security analysts need to understand them: as pathways that shape exposure, logging, and containment options. You will define virtual networks, subnets, route tables, security groups, and DNS resolution, then connect each component to typical failure modes like unintended internet reachability, lateral movement opportunities, and blind spots in flow visibility. We will walk through how routing decisions influence which logs exist, where traffic can be inspected, and why “it works” in a deployment does not mean it is secure. You will also learn practical troubleshooting questions for incidents, such as verifying name resolution behavior, identifying split-horizon DNS risks, and validating that segmentation is enforced at the right layer. Expect exam-relevant reasoning about shared responsibility and what evidence proves a network boundary is real.
