Level Up Your Column-level Security: Using IAM Data Governance Tags in BigQuery

TL;DR

BigQuery has introduced IAM Data Governance Tags to enhance column-level security, addressing the limitations of traditional policy tags. This new approach allows for more granular access control over sensitive data, such as personally identifiable information (PII).

✦ Why It Matters

Implement IAM Data Governance Tags in your BigQuery projects to enhance data security and compliance today.

Key Takeaways

Create data governance tag keys for column security.
Utilize JSON schema to attach tags to BigQuery columns.
Define data policies to control access based on tags.
Leverage hierarchical tagging for granular data classification.

How It Works

Data governance tags are created by setting the purpose field to DATA_GOVERNANCE in IAM, allowing for a hierarchical structure of tags. This enables organizations to define broad categories and drill down into specific classifications, enhancing access control.
