Microsoft Sentinel

Microsoft's cloud-native SIEM and SOAR solution built on Azure Log Analytics.

Definition

Sentinel ingests data through data connectors, detects threats with analytics rules (scheduled, near-real-time, Fusion and Microsoft security rules), groups alerts into incidents and automates response with automation rules and Logic Apps playbooks. Queries use KQL, and Sentinel is integrating into the unified Microsoft Defender portal.

Example

A scheduled analytics rule running a KQL query every 5 minutes to detect password spraying.

Exam tip

Sentinel playbooks are Azure Logic Apps; automation rules trigger them.
