Discussion

Under some circumstances, it may be useful to monitor who/what is reading privilege/permission/role information; therefore, it must be possible to configure auditing to do this. DBMSs typically make such information available through views or functions. This requirement addresses explicit requests for privilege/permission/role membership information. It does not refer to the implicit retrieval of privileges/permissions/role memberships that Azure SQL Managed Instance continually performs to determine if any and every action on the database is permitted. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones. Satisfies: SRG-APP-000091-DB-000066, SRG-APP-000091-DB-000325, SRG-APP-000495-DB-000326

Review Azure SQL Managed Instance configuration to verify that audit records are produced when privileges/permissions/role memberships are retrieved.  

To determine if an audit is configured, follow the instructions below: 

Run this TSQL command to determine if SQL Auditing AuditActionGroups are configured:
  
SELECT DISTINCT sd.audit_action_name
FROM sys.server_audit_specification_details sd
JOIN sys.server_audit_specifications s
ON s.server_specification_id = sd.server_specification_id
WHERE s.is_state_enabled = 1
ORDER BY sd.audit_action_name

If no values exist for AuditActionGroup, this is a finding.  

Verify the following AuditActionGroup(s) are configured:  

SCHEMA_OBJECT_ACCESS_GROUP  

If any listed AuditActionGroups do not exist in the configuration, this is a finding.
