Fine-Grained Access Control for Unstructured Data With Volume Path Policies

Unstructured data — images, documents, videos and more — is growing in importance with AI and ML. Yet managing access control at scale is challenging. Unity Catalog Volumes offer a secure foundation, but access control has remained volume-level — until now. This session introduces Volume Path Policies, a new feature enabling fine-grained access within volumes. Built on Unity Catalog’s ABAC (Attribute-based Access Control), they let you define rules for users and groups based on path prefixes. We’ll cover the governance model, share examples and demonstrate how to enforce least-privilege access. By the end, you’ll know how to manage file-level access with Unity Catalog’s flexibility and control.
