AWS GovCloud Launches IAM-Based Authorization for Amazon S3 Tables and Iceberg Materialized Views
This security and administration update simplifies the access control model for organizations operating in the AWS GovCloud (US) Regions. Previously, managing permissions for transactional data lake tables required coordinating separate access policies across Amazon S3 storage bucket resources and the AWS Glue Data Catalog. With the launch of IAM-based authorization, operations are streamlined into a cohesive permissions framework.

Action Checklist
- Identify existing S3 Tables and Apache Iceberg materialized views in AWS GovCloud Verify that your current workloads are running on supported versions of AWS Glue
- Draft consolidated IAM policies using the new unified authorization structure Ensure policies accurately define access across storage, catalog, and query layers
- Test the updated IAM policies in a non-production environment Check for any unintended access denials from deprecating older, separate policies
- Apply the new IAM policies to your AWS GovCloud production resources Monitor access logs to confirm query engines and catalog operations resolve correctly
