The Microsoft Sentinel Fundamentals course provides a comprehensive overview of the Microsoft cloud-native SIEM and SOAR platform. It begins with an introduction to Sentinel's architecture, highlighting how it aggregates data across users, devices, and applications to provide a bird's-eye view of an organization's security posture. The curriculum then dives into Threat Intelligence, teaching students how to ingest and manage indicators of compromise (IOCs) from various feeds to proactively identify malicious activity. Central to the course is Analytics, where learners master the Kusto Query Language (KQL). Through KQL, you'll learn to write high-performance queries to filter massive datasets, build custom detection rules, and hunt for sophisticated threats.
