Your guide to fine-grained access control: Permissions, ABAC, and RBAC in Unity Catalog

Fine-grained access control in Unity Catalog isn’t a set of disconnected features; it’s a unified framework. Understanding how permissions, RBAC and ABAC work together is key to governing data and AI at scale.

In this session, we’ll break down each approach and when to use it. Learn how granular permissions enforce least privilege, how RBAC creates clear isolation boundaries and how ABAC uses governed tags to apply row filters, column masks and policy logic across entire catalogs automatically.

We’ll walk through this as a progression — from dynamic views and table-level controls to scalable, tag-driven policies — so you know how to evolve your approach as your data estate grows. We’ll also cover performance considerations, how to avoid conflicts when combining methods and real-world patterns for production environments.

Finally, we’ll preview what’s next, including extending fine-grained governance to AI assets and unstructured data, along with new visibility and impact analysis capabilities in Unity Catalog.

Walk away with practical guidance to design, scale and future-proof access control.
