Episode 42 — Control storage permissions with least privilege and tight data boundaries
This episode focuses on designing storage permissions so access is intentional, reviewable, and limited to the smallest practical scope, which maps directly to exam questions about effective access and real-world questions about containment. You’ll define identity-based permissions versus resource-based permissions, then learn how scoping works at the level of accounts, projects, resource groups, buckets, containers, and prefixes so you can prevent a role that needs one dataset from gaining visibility into everything. We’ll explore boundary design for sensitive data, including separating environments, separating regulated data, and minimizing cross-team access by default, then apply those concepts to a scenario where a shared “data engineering” role can read multiple business units’ exports because no boundaries were enforced. You’ll also cover troubleshooting considerations such as broken applications after permission tightening, how to identify the missing action without resorting to wildcards, and how to prove the final policy meets functional needs while closing the original overreach.
