Guardians of the lake: Securing your data with OneLake Security in Fabric
Session Overview: As organizations centralize their data in Microsoft Fabric, OneLake becomes the single source of truth but with that power comes the responsibility to secure it correctly.
In Guardians of the Lake, we move beyond basic access control to explore how OneLake security enables true, enterprise-grade data protection at scale. This session dives into how role-based access, row-level, and column-level security work together to control not just who can access data but what they can see and how they can use it.
You’ll learn how to design a security model that aligns with business roles, scales across domains, and supports both self-service analytics and strict governance requirements. We’ll also cover how OneLake security integrates with Fabric workloads, shortcuts, and shared data architectures highlighting real-world challenges, limitations, and lessons learned from early adoption.
Through practical examples and proven patterns, this session will show how to transform OneLake from a data repository into a governed, secure foundation for analytics ensuring your organization can unlock insights without compromising control.
Learning Objectives:
- Design a scalable OneLake security model using roles, row-level, and column-level controls: Learn how to structure access using role-based security and fine-grained controls to align data visibility with business roles and organizational boundaries.
- Implement governance strategies that balance self-service analytics with enterprise security: Understand how to enable broad data access for analytics while enforcing policies that protect sensitive information and maintain compliance.
- Identify limitations, edge cases, and real-world patterns when securing data in OneLake: Explore common challenges—such as shortcuts, cross-workspace access, and inheritance—and learn proven approaches to ensure consistent and effective security.
