Episode 71 — Build Network Security Architecture Using Trust Models and Control Placement
This episode explains how to think about network security architecture as a set of intentional trust decisions and control placement choices that determine whether attacks spread or stop, which maps directly to exam objectives on network security architecture and common threat mitigation. You will learn what a trust model is in practical terms, how implicit trust differs from verified trust, and how to place controls at the right boundaries so they protect high-value paths rather than creating security theater. We cover examples such as protecting identity systems, restricting management planes, separating internet-facing services from sensitive data stores, and aligning segmentation decisions with monitoring so defenders can detect and respond when controls are tested. Troubleshooting considerations include designs that rely on a single control, flat internal networks built for convenience, undocumented traffic flows that encourage dangerous exceptions, and architecture drift caused by unmanaged changes, all framed as repeatable decisions leaders must govern over time.
