Description
Changes to the security configuration must be tracked. This requirement applies to situations where security data is retrieved or modified via data manipulation operations, as opposed to via specialized security functionality. In an SQL environment, types of access include, but are not necessarily limited to: SELECT INSERT UPDATE DELETE EXECUTE

Review Azure SQL Database configuration to verify that audit records are produced when security objects are accessed. To determine if an audit is configured, execute the following script. 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 security objects are accessed.

To determine if an audit is configured, execute the following script.
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.
