Azure Sentinel is a cloud-native SIEM (Security Information and Event Management) and SOAR (Security Orchestration, Automation, and Response) solution built for Microsoft Azure. It ingests security data from various sources, analyzes it using advanced analytics, and automates security operations. Azure Sentinel uses KQL (Kusto Query Language) to query and analyze security data. Its primary function is to centralize security data, detect threats, and automate response actions.
Sentinel offers a unified platform for security analytics, threat hunting, and incident response, integrating with Microsoft 365 Defender and other security data sources. It supports a wide range of data ingestion methods, allows for customizable detection rules, and features a powerful KQL query language for advanced analysis. Its integration with Azure automation enables automated response playbooks, significantly streamlining security workflows.
