Azure SQL DB must generate audit records when categorized information (e.g., classification levels/security levels) is accessed.

Description
Changes in categorized information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected. For detailed information on categorizing information, refer to FIPS Publication 199, Standards for Security Categorization of Federal Information and Information Systems, and FIPS Publication 200, Minimum Security Requirements for Federal Information and Information Systems.

Review Azure SQL Database configuration to verify that audit records are produced when categorized information is 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.
