什么是 ABAC？

Databricks has announced the general availability of three complementary capabilities in Unity Catalog: Attribute-Based Access Control (ABAC) policies for row filtering and column masking, governed tags, and agentic data classification, enabling dynamic, standardized, and automated data governance.

Databricks introduces Cross-Engine ABAC, unifying fine-grained access control across multiple data engines with attribute-based, zero-trust policies, supporting Delta Lake, Databricks SQL, and Notebooks, significantly reducing configuration complexity and enhancing security and governance efficiency.

Unity Catalog prevents unauthorized AI agent operations through fine-grained access control, audit logging, and AI-specific governance frameworks, ensuring secure and controllable enterprise AI applications.
