Level Up Your Column-level Security: Using IAM Data Governance Tags in BigQuery
BigQuery introduces data governance tags, built on IAM's Resource Manager, to provide a scalable and robust method for managing access controls and protecting column data. This feature offers a global scope, managed disaster recovery, hierarchical security, and decoupled governance. It replaces policy tags and allows for more granular classification and inheritance. Users can create a hierarchical tree of data governance tags and apply them directly to BigQuery columns. This feature is now in preview.
