Fix Recommendation

Add and/or update system documentation to include any accounts authorized for object ownership and remove any account not authorized.

To change the schema owning a database object in SQL Server, use this code as an example:

USE AdventureWorks2012;
GO
ALTER SCHEMA HumanResources TRANSFER Person.Address;
GO

Caution: This can break code. This Fix should be implemented in conjunction with corrections to such code. Test before deploying in production. Deploy during a scheduled maintenance window.

Check Contents

Review system documentation to identify SQL Server accounts authorized to own database objects.

If the SQL Server database ownership list does not exist or needs to be updated, this is a finding.

The following query can be of use in making this determination:

;with objects_cte as
(SELECT o.name, o.type_desc,
CASE
WHEN o.principal_id is null then s.principal_id
ELSE o.principal_id
END as principal_id
FROM sys.objects o
INNER JOIN sys.schemas s
ON o.schema_id = s.schema_id
WHERE o.is_ms_shipped = 0
)
SELECT cte.name, cte.type_desc, dp.name as ObjectOwner
FROM objects_cte cte
INNER JOIN sys.database_principals dp
ON cte.principal_id = dp.principal_id
ORDER BY dp.name, cte.name

If any of the listed owners is not authorized, this is a finding.
