Control: 8 Amazon Redshift clusters should not use the default Admin username
Description
This control checks whether a Amazon Redshift cluster has changed the admin username from its default value. This control will fail if the admin username for a Redshift cluster is set to awsuser.
When creating a Redshift cluster, you should change the default admin username to a unique value. Default usernames are public knowledge and should be changed upon configuration. Changing the default usernames reduces the risk of unintended access.
Remediation
You cannot change the admin username for your Amazon Redshift cluster after it is created. To create a new cluster, follow the instructions here.
Usage
Run the control in your terminal:
powerpipe control run aws_compliance.control.foundational_security_redshift_8Snapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe control run aws_compliance.control.foundational_security_redshift_8 --shareSQL
This control uses a named query:
redshift_cluster_no_default_admin_name
