Detection engineering is the practice of designing, building, and maintaining detection rules that identify malicious activity in your environment. The MITRE ATT&CK framework provides a structured approach to understanding adversary behavior.
This post covers the methodology I use to create detection rules that map directly to ATT&CK techniques, ensuring comprehensive and measurable detection coverage.
Topics include: - Understanding ATT&CK data sources - Writing Sigma rules - Testing detections with atomic tests - Measuring coverage gaps
