Office 365 Unified Audit Log Enabled
This rule detects when the Unified Audit Log is enabled in Office 365. This event is triggered when the 'Set-AdminAuditLogConfig' cmdlet is used to set 'UnifiedAuditLogIngestionEnabled' to 'True'. While enabling logging is generally a positive security action, this rule is designed to alert if logging was previously disabled and is now being re-enabled, which could indicate an adversary attempting to cover their tracks after a period of operating without logging, or to restore logging after intentionally disabling it.
