Practical Detection Engineering with Sigma is a hands-on guide to building, testing, and operationalizing modern detections in real SOC environments. The book walks you step by step through the full detection engineering lifecycle—from understanding Sigma fundamentals to writing structured rules and deploying them across SIEM and XDR platforms. You will learn how to translate adversary behavior into behavior-based detections, aligned with MITRE ATT&CK, create rules for Windows, Linux, and network telemetry, and convert them into backend-specific queries for platforms such as Elastic, Splunk, Microsoft Sentinel, and Wazuh. Practical examples demonstrate how to validate detections using real and simulated attack data, reduce false positives, and design alerts that analysts can confidently triage. From rule creation to CI/CD automation, version control, and large-scale rule management, this book equips you to build scalable, maintainable, and production-ready detection programs aligned with modern security operations.
Wojciech Ciemski is a cybersecurity engineer and detection specialist with over a decade of hands-on experience. His work focuses on detection engineering, Sigma Rule Language, and research-driven analysis of adversary behavior mapped to MITRE ATT&CK. He designs and tests scalable SIEM and XDR detection pipelines, based on real-world threat data.
