Detection Engineering: Writing and Tuning Detection Rules (Sigma/YARA)

<p>A story-driven walkthrough of detection engineering: what separates a durable detection practice from one-off ad hoc alerts, how to write a Sigma rule for a specific log-based behavior and map it to a real SIEM query, how to write a YARA rule to fingerprint a malicious file, how to test and tune rules against real production traffic to control false positives without losing coverage, and how to ship detection rules through a version-controlled, CI-tested detection-as-code pipeline.</p>

Tools: Sigma, YARA, SIEM, MITRE ATT&CK, CI/CD
