Episode 51 — Authn, Authz, IAM, and 2-Step Verification

Authentication, authorization, and identity management form the backbone of secure cloud operations. This episode clarifies how these components interact in Google Cloud—a topic featured prominently in the Google Cloud Digital Leader exam. Authentication, often shortened to “authn,” verifies who a user or system is. Authorization, or “authz,” determines what that user can do once verified. Identity and Access Management, abbreviated as IAM, provides the framework to assign roles, permissions, and policies that enforce least privilege across all resources. Two-step verification adds a second layer of protection, confirming identity through additional factors such as hardware keys or device prompts. Together, these layers create the trust boundary that governs every access decision.We explore scenarios showing how misconfigured permissions can lead to data exposure and how proper IAM design reduces risk. In practice, administrators use predefined roles, custom roles, and service accounts to manage access precisely. Two-step verification strengthens defense against compromised credentials, an increasingly common attack vector. For exam readiness, remember that IAM is both a security and governance tool—it helps organizations enforce compliance, accountability, and operational efficiency.
