Covers four operational modes: reactive (post-incident investigation), proactive (threat modeling), full-cycle (building a CTI program), and adversary emulation. Key practices include structured evidence inventory with chain-of-custody hashing, evidence labeling (CONFIRMED/CORROBORATED/INFERRED/HYPOTHESIZED), a claims ledger linking every assertion to specific log lines, ATT&CK mapping with gap classification, and Sigma rule derivation for missed detections. The methodology uses a GitHub repository with Docker-based lab stack (OpenCTI, TheHive, Elastic), templates for each mode, and 8 fully worked training assignments. Git commits serve as the audit trail, making investigations reproducible and institutional knowledge persistent. ## Full article daily.dev links to this article rather than hosting it.
