Description
For completeness of forensic analysis, it is necessary to track who/what (a user or other principal) logs on to Azure SQL Database.

ℹ️ Check
Review Azure SQL Database configuration to verify that audit records are produced when successful logons or connections occur. 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: SUCCESSFUL_DATABASE_AUTHENTICATION_GROUP If any listed AuditActionGroups do not exist in the configuration, this is a finding.

✔️ Fix
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
