Fabric Monday 110: Onelake Row and Column Security

DennesTorres — Sun, 12 Apr 2026 19:49:32 GMT

🔐 How many places in Microsoft Fabric do you define who sees what? 🤔

🧩 Semantic model → its own RLS
🧩 SQL Endpoint → its own access rules
🧩 Spark notebook → another layer

Each one enforced independently.
Each one maintained separately.
Each one a place where something can drift.

🎯 OneLake Security defines security once — at the storage layer.

🔸 Row-Level Security → SQL WHERE clause, scoped per role
🔸 Column-Level Security → control exactly which columns each role can see

One definition.
Automatically enforced across Spark, SQL Endpoint, Power BI — every engine reading the data.

⚠️ What to know before you start:

→ RLS and CLS must live in the same role when used together
→ Mixing them across roles breaks queries entirely
→ Once you enable OneLake Security on an item, it cannot be turned off

Awesome security(preview) feature. Have used it a few weeks ago for a POC successfully.
