Episode 5 — Strengthen Computer Networking Fundamentals: Packets, Sessions, and Trust Boundaries (Task 5)
This episode reinforces core networking fundamentals that appear in detection, incident questions, and control design across the exam. You will define packets, flows, sessions, and common protocol behaviors, then use those definitions to explain why some attacks are visible in one telemetry source and invisible in another. We will connect networking fundamentals to trust boundaries, showing how authentication, encryption, and routing choices determine where you can enforce policy and where you can only observe. You will hear practical examples such as why DNS patterns can reveal command and control staging, how session resets affect alert interpretation, and what “east-west” traffic implies during lateral movement. By the end, you should be able to read a network-centric exam question and quickly identify the right layer for investigation and the most defensible containment move.
