NXLog DNS Logs connector for Microsoft Sentinel

The NXLog DNS Logs data connector uses Event Tracing for Windows (ETW) for collecting both Audit and Analytical DNS Server events. The NXLog im_etw module reads event tracing data directly for maximum efficiency, without the need to capture the event trace into an .etl file. This REST API connector can forward DNS Server events to Microsoft Sentinel in real time.
