Exploring permission boundaries in Microsoft Fabric

Proposed session for SQLBits 2026

TL; DR

An overview of Microsoft Fabric permissions and data security in a lakehouse architecture. Learn how to design scalable, least-privilege access strategies that balance governance, flexibility, and real-world business use cases.

Session Details

Microsoft Fabric offers a wide range of options to define permissions for both item and data access, using different scopes of the platform. As options keep evolving, it's a challenge to determine a viable permission strategy that works for the use cases at hand, offers business users the flexibility they are looking for, and passes those dreaded security checks to be able to move to production.

Focusing on a typical lakehouse architecture for data analysis using Microsoft Fabric, we'll explore the different options that exist to provide access to items and define data security rules. We'll discuss how these different options can impact business users, walking through pros and cons, and providing examples that are manageable and usable at scale. Above all, the guiding principle of least privileged access is our north star, making sure we do our part to keep company data safe.

We'll tie personas and use cases to common data access patterns and assess how Microsoft Fabric can help us get the data closer to where the business user is, helping them to make better informed decisions using validated data.

After wrapping up the walkthrough, people should feel informed about the different options that exist, empowered to make their own decisions based on their own use cases and requirements, and reassured that it really isn't that complicated as it seems.

3 things you'll get out of this session

- Describe the permission and security model options available in Microsoft Fabric - Design item- and data-level access strategies for a lakehouse architecture - Evaluate the pros and cons of different permission approaches for business users - Apply the principle of least-privileged access to real-world Fabric scenarios - Map personas and use cases to appropriate data access patterns - Make informed, scalable security decisions that balance governance and usability

Asking questions to get meaningful answers
By making sure we're supplying the other party with the compact information they need, and making sure we're "forcing" them to give a decent answer, there's a lot more information we can receive. By getting the information we need, we'll be able to proceed quicker, and getting to results faster.
 
Setting yourself up for success when submitting to present
During this session we'll cover how you find those elusive speaking opportunities and how you can make the most of it with just a few simple things to keep in mind. Most importantly, what can you do to help understand organizers or selection committees why exactly your session would be a good fit for them, and why you think it would be a good fit for their audience.
 
Star Schema ALL the things! But why?
Come along in this journey from source to model to report using a practical mindset, thinking about the design decisions and ramifications along the way. At the core of the session lies the message to think about best practices, with the added step to test, assess, and benchmark what exactly they do for you.
 
You're a Power BI Admin? Let's get your threads aligned for Fabric!
This session will focus on the life of a Power BI Admin moving over to the extended Fabric realm, and keeping their things in check. We'll look at the familiar topics of capacity and workspace management, and how they align with the new workloads that have been introduced. We'll notice there's a very large overlap, as Fabric has been built on the foundations of Power BI.
