Episode 54 — Infrastructure Protection: Device Placement, Security Zones, Attack Surface, and Diversity (3.2)
This episode introduces infrastructure protection by focusing on where controls are placed and how environments are divided. Students should understand that device placement affects visibility, enforcement, and risk, such as placing firewalls, sensors, proxies, and gateways where they can inspect the right traffic. Security zones separate systems by trust level, sensitivity, function, or exposure. Attack surface reduction removes unnecessary services, access paths, devices, and features that attackers could target. Technology diversity can reduce common failure risk but may increase operational complexity. For the exam, students should connect design choices to segmentation, monitoring, control effectiveness, and limiting the impact of compromise.
