  'This query looks for Microsoft Defender for Endpoint detections related to the remote command execution attempts on Azure IR with Managed VNet or SHIR. 
  In Microsoft Sentinel, the SecurityAlerts table includes the name of the impacted device. Additionally, this query joins the DeviceInfo table to connect other information such as device group, IP address, signed in users, and others allowing analysts using Microsoft Sentinel to have more context related to the alert.
