# IAM policy requirements for accessing clusters and namespaces registered to the Data Catalog
<a name="iceberg-integration-iam"></a>

This topic describes the required IAM permissions for registering provisioned clusters and serverless namespaces to the Data Catalog and accessing them with Amazon Redshift.

After you register a provisioned cluster or serverless namespace to the AWS Glue Data Catalog, you need the following permissions to discover the creation of and changes to the subsequently created catalog. 
+ `glue:GetCatalog`
+ `glue:GetCatalogs`
+ `lakeformation:GetDataAccess`

These permissions are included in the service-linked role `AmazonRedshiftServiceLinkedRolePolicy`. For more information on this role, see [ Using service-linked roles for Amazon Redshift](https://docs.aws.amazon.com/redshift/latest/mgmt/using-service-linked-roles.html) in the *Amazon Redshift Management Guide*.
