The Azure SQL Database must be able to generate audit records when unsuccessful attempts to retrieve privileges/permissions occur.

Description
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 Database 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.

Review Azure SQL Database configuration to verify that audit records are produced when the system denies or fails to complete attempts to retrieve privileges/permissions/role membership. 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.database_audit_specification_details sd JOIN sys.database_audit_specifications s ON s.database_specification_id = sd.database_specification_id WHERE (name = 'SqlDbAuditing_ServerAuditSpec' /Server Audit/ OR name = 'SqlDbAuditing_AuditSpec') /Database Audit/ AND 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.

Review Azure SQL Database configuration to verify that audit records are produced when the system denies or fails to complete attempts to retrieve privileges/permissions/role membership.

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.database_audit_specification_details sd
JOIN sys.database_audit_specifications s
ON s.database_specification_id = sd.database_specification_id
WHERE (name = 'SqlDbAuditing_ServerAuditSpec' /*Server Audit*/
OR name = 'SqlDbAuditing_AuditSpec') /*Database Audit*/
AND 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.
