The Definitive Guide to KQL: Using Kusto Query Language for operations, defending, and threat hunting

For security analysts, operations teams, and anyone working with Microsoft’s cloud data platforms, Kusto Query Language (KQL) has become an essential skill. The Definitive Guide to KQL takes you from the fundamentals of querying to advanced techniques used in real-world threat hunting and operational monitoring.

Why This Book Stands Out 💻

Written by Microsoft insiders with deep experience in security and IT operations, this guide goes beyond basic syntax. It shows how KQL can be applied to investigate incidents, detect anomalies, and make sense of large-scale telemetry.

Inside the Book

• Foundations: query structure, data types, common operators, and environment setup.
• Data aggregation: min/max, average, sum, binning, and visualization techniques.
• Advanced operators: variables, unions, joins, external data, and optimization practices.
• Operational excellence: using KQL for monitoring and managing services.
• Cybersecurity use cases: defending, threat hunting, and advanced security investigations.

From First Query to Security Insights 🛡️

Each chapter builds practical skills with clear examples and explanations. You’ll learn how to write queries that uncover meaningful patterns in logs and security events, then apply those skills to Microsoft Sentinel, Azure Data Explorer, and Log Analytics workflows.

Who Benefits Most

Security analysts, SOC teams, IT administrators, and anyone responsible for extracting value from Microsoft data platforms will find this guide a reliable companion. Whether you’re new to KQL or looking to sharpen your threat hunting toolkit, the book offers structured, actionable knowledge.
