The use of Power BI is increasing rapidly. With it, data security increasingly becomes a key requirement of a Power BI solution. How do you ensure that users have access to the information they need? In Power BI, security within a data model can be implemented through row-level security (RLS). With RLS, complete parts of the model can be hidden from a user. But without careful design, you will run into errors or even expose more data than you think. In this session, you will learn about RLS and how to avoid some of the pitfalls in modeling for security.
