Scale fine-grained permissions across warehouses with Amazon Redshift and AWS IAM Identity Center

This article explains how to implement Amazon Redshift federated permissions with AWS IAM Identity Center to manage fine-grained access controls across multiple data warehouses.

• Federated permissions enable defining security policies once in a central warehouse and automatically enforcing them across all warehouses
• Supports integration with external identity providers like Microsoft Entra ID, Okta, and Ping Identity
• Multi-region support allows extending IAM Identity Center across AWS regions based on data residency requirements
• Dynamic data masking protects PII by masking sensitive fields like customer dates of birth
• Row-level security controls data visibility based on user roles and organizational requirements
• Trusted identity propagation maps IdP groups to Redshift database roles for seamless access management
• Practical example demonstrates Enterprise Data Warehouse sharing policies with Sales and Marketing warehouses
• Reduces administrative overhead through centralized policy management instead of manual replication

The solution provides streamlined multi-warehouse data governance by centralizing security policy definitions and automatically enforcing them consistently across connected data warehouses in the same account and region.
