Explanation

In a data lake architecture, the Raw zone holds data exactly as it was ingested from source systems - unprocessed, unvalidated, and potentially containing sensitive personal information in its original form. Because this zone stores data before any transformation or masking has been applied, it poses the highest exposure risk and therefore requires encryption or tokenization to protect sensitive data at rest. The Trusted and Clean zones typically contain data that has already been processed, validated, or de-identified. A Temporal zone is a transient staging area and is less commonly referenced in this context.
