Episode 16 — Reduce permission blast radius with scoped roles and resource segmentation
This episode ties least privilege to blast-radius reduction by showing how role scope and resource segmentation work together to limit what any single identity can affect. You’ll define scope as the boundary where permissions apply, and segmentation as the way resources are grouped so controls can be applied cleanly—by environment, application, data classification, or business unit. We’ll connect these concepts to exam questions that ask you to choose the “best” control when an identity must perform a task but should not gain broad influence across unrelated resources. A scenario demonstrates a service identity that needs to write logs for one application; without segmentation it is given permissions that allow modification of shared network components, but with segmentation it is limited to a narrow resource group or project. You’ll also learn real-world pitfalls, like overly generic resource group design, inherited permissions that bypass segmentation intent, and missing tagging standards that make scoping hard to maintain.
