Problem

We operate a multi-tenant data lake used by five different business units, each with different data sensitivity levels and compliance requirements. Currently all data is stored in a flat structure with a single shared reader role. We have had two incidents where engineers accessed data from a different business unit. Design a file-level access control architecture for the data lake.

Summary

Two incidents. One shared lake. The access model was never designed, just assumed.
