Episode 74 — Identify Common Network Threats and Map Them to Defensive Priorities
This episode teaches how to recognize common network threats and translate them into prioritized defensive actions, aligning with exam objectives that test risk-based thinking in network contexts. You will learn how scanning, exploitation, credential abuse, man-in-the-middle attempts, and lateral movement typically appear, and how to prioritize defenses based on exposure, impact, and likelihood rather than treating every threat equally. We cover practical mapping from threats to controls, such as identity hardening and MFA for credential abuse, segmentation for lateral movement, TLS verification for interception risk, and monitoring patterns that reveal suspicious connections, unusual authentication behavior, and abnormal data movement. A scenario-driven walkthrough ties these ideas together by showing how a single compromised credential can become a network-wide incident in a flat environment, and how layered controls reduce both probability and blast radius. Troubleshooting considerations include overfocusing on external threats while ignoring internal movement, relying on tools without use cases and tuning, and failing to coordinate network defense priorities with incident response playbooks and evidence requirements.
