Write Once, and Detect Everywhere- Practical Sigma Rules for Modern SOCs
Book Description
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.
What you will learn
? Design and write structured, maintainable Sigma rules for diverse log sources and enterprise environments.
? Translate adversary techniques into behavior-based detections, aligned with MITRE ATT&CK tactics and techniques.
? Convert vendor-agnostic Sigma rules into optimized SIEM and XDR platform-specific queries.
