KQL Query Building for Sentinel Security Analysis

In modern security operations, the ability to quickly extract insights from massive volumes of log data is a critical skill. This text-based course teaches you how to write Kusto Query Language (KQL) statements to effectively analyze security logs and detect threats within Sentinel. By working through clear, step-by-step written explanations and practical query examples, you will transform from a beginner into a confident analyst capable of querying diverse data sources. You will learn how to navigate the database schema, filter out noise, and pinpoint malicious activity. What you'll learn: - Understand KQL syntax, basic operators, and foundational security log structures. - Filter, sort, and format security event data to isolate critical alerts. - Summarize and aggregate large datasets to identify patterns and anomalies. - Correlate events across multiple tables using joins, unions, and lookups. - Optimize query performance for faster threat detection and reduced resource usage. - Write basic threat hunting queries to proactively identify security risks. The course begins with essential terminology, database concepts, and the structure of KQL, before guiding you through progressively advanced filtering, aggregation, and correlation techniques. It is designed specifically for beginners with no prior query language or database experience. Start reading today to build the essential query skills needed for modern security analysis.
