Detection engineering (the pipeline)

When it applies

You have alerts but no system: rules nobody trusts, unknown coverage, and detections that die on the next log-schema change. This is the lifecycle that turns "we should alert on X" into a tested, versioned, measured detection.

Why it works

Detections are software. Treating them as code — with a source of truth, tests, and a coverage metric — is what separates a SOC that improves from one that just accrues noise. ATT&CK gives a shared map so coverage and gaps are countable, not vibes.
