Title
Azure SQL Database must generate audit records when security objects are modified. (Cat II impact)
Discussion
Changes in the database objects (tables, views, procedures, functions) that record and control permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized changes to the security subsystem could go undetected. The database could be severely compromised or rendered inoperative.
Check Content
Review Azure SQL Database configuration to verify that audit records are produced when security objects are modified. 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_CHANGE_GROUP If any listed AuditActionGroups do not exist in the configuration, this is a finding.
Fix Text
Deploy an Azure SQL Database audit. Refer to the supplemental file "AzureSQLDatabaseAudit.txt" PowerShell script. Reference: https://docs.microsoft.com/en-us/powershell/module/az.sql/set-azsqlserveraudit">https://docs.microsoft.com/en-us/powershell/module/az.sql/set-azsqlserveraudit
