Data security is an important part of any data architecture design, and there are some unique Microsoft Fabric features that should be employed to improve the security of your data estate.

In this webinar we will review the different layers of security, including OneLake Security, Entra ID authentication and Role-Based Access Control across workspaces, lakehouses, warehouses, and semantic models. We’ll examine how sharing, shortcuts, and cross-workspace access behave in practice, where security assumptions commonly fail, and how to avoid accidental data exposure. You’ll learn how to implement least-privilege access, layer Row-Level Security in semantic models, and validate your design through testing.

Attendees leave with practical patterns to secure OneLake in real-world, multi-team and multi-tenant environments.
