Which component of Microsoft Sentinel uses Azure Logic Apps for automation in response to alerts?

The component of Microsoft Sentinel that uses Azure Logic Apps for automation in response to alerts is indeed playbooks. Playbooks in Microsoft Sentinel are designed to execute automated responses to incidents based on certain conditions or alerts. They facilitate the orchestration of workflows using Azure Logic Apps, allowing users to automate tasks such as sending notifications, collecting data, or triggering additional processes in response to detected threats.

By leveraging Azure Logic Apps, playbooks enable integration with various services and tools, enhancing the overall incident response capabilities of Microsoft Sentinel. This automation is crucial for streamlining operations and ensuring timely responses to security incidents, thereby improving the effectiveness of a security posture. In contrast, analytic rules are primarily used to identify potential threats, hunting queries help in actively looking for unknown threats, and workbooks provide visualization and reporting on security data, all of which do not directly involve automation in response to alerts.
