Title
Azure SQL Database must generate audit records when unsuccessful logons or connection attempts occur. (Cat II impact)
Discussion
For completeness of forensic analysis, it is necessary to track failed attempts to log on to Azure SQL Database. While positive identification may not be possible in a case of failed authentication, as much information as possible about the incident must be captured.
Check Content
Review Azure SQL Database configuration to verify that audit records are produced when unsuccessful logons or connection attempts 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: FAILED_DATABASE_AUTHENTICATION_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
