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.
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.
● Validate and test detections using real telemetry, simulated attacks, and threat emulation frameworks.
● Reduce false positives through better logic design, field normalization, and contextual enrichment.
● Implement scalable detection engineering practices using Git-based versioning, automation, and CI/CD pipelines.
