Threat Hunting with YARA and Sigma for SOC Analysts

In modern security operations, quickly identifying malicious activity across files, memory, and logs is the difference between a minor incident and a devastating breach. This course guides you through the foundational concepts of YARA and Sigma, the two industry-standard languages for threat detection. You will transition from understanding basic security concepts to writing custom detection rules that hunt down threats across your network and endpoints. What you will learn: 1. Understand the fundamental syntax and structure of YARA and Sigma rules. 2. Create YARA rules to scan files, memory, and active processes for malware. 3. Write Sigma rules to detect suspicious event logs and normalize detection across different SIEM platforms. 4. Apply modern detection-as-code workflows to manage and version-control your rule library. 5. Analyze threat indicators to translate intelligence into actionable detection logic. The course begins with core definitions of threat hunting and rule-based detection, establishing a solid conceptual foundation before progressing step-by-step through syntax and practical writing scenarios. Designed for aspiring SOC analysts, junior security engineers, and IT professionals, this course requires no prior experience with detection engineering.
