Episode 8 — Use Structural Security Design Principles to Prevent Predictable Failure Modes
This episode focuses on structural design principles that reduce predictable security failures before you get to control lists or tooling choices. We define principles like least privilege, separation of duties, fail-safe defaults, complete mediation, and economy of mechanism, and we connect each one to the kinds of incidents it helps prevent. You’ll hear how these principles show up in system architecture decisions, such as service boundaries, administrative workflows, key management paths, and data movement, and how to spot when a design violates them. We also cover troubleshooting patterns, like why overly complex access paths create bypasses, or why shared service accounts quietly defeat segmentation. For the exam, we practice identifying which principle a question is testing, then choosing the response that changes system structure in a durable way instead of adding a brittle compensating control that won’t survive the next release.
