AlienApp for Microsoft Defender ATP Actions

The AlienApp for Microsoft Defender Advanced Threat Protection (ATP) provides a set of orchestration actions that you can use to respond to threats forwarded from your Microsoft Azure Events Hub.

As USM Anywhere surfaces events Any traffic or data exchange detected by AT&T Cybersecurity products through a sensor or external devices such as a firewall., vulnerabilities, and alarms Alarms provide notification of an event or sequence of events that require attention or investigation., your team determines which items require a response action. Rather than manually tagging threats, you can use the AlienApp for Microsoft Defender ATP orchestration actions to enforce protection based on the information associated with the event or alarm. The following table lists the available actions from the AlienApp.
