Episode 6 — Apply Trust Concepts and Hierarchies to Real System Security Boundaries
This episode teaches trust as an engineering property you deliberately assign and continuously verify, not a vibe you assume because a component is “internal.” We define trust boundaries, trusted computing base concepts, and trust hierarchies, then show how they shape authentication, authorization, data handling, and segmentation decisions. You’ll learn how to identify where implicit trust creeps in, like shared admin tools, management networks, service-to-service calls, or “temporary” exceptions that become permanent. We also cover practical ways to reduce trust, such as minimizing privileged paths, isolating control planes, and requiring verifiable claims at boundaries, along with troubleshooting signals that your trust model is wrong, like unexpected lateral movement or brittle incident containment. For the exam, you’ll practice mapping a scenario to trust zones and choosing the control that strengthens the boundary instead of adding noise somewhere else.
