From alert fatigue to detection engineering

Alert fatigue is rarely a staffing problem. It is a quality problem: detections written once, never tested, never retired. Detection engineering borrows the discipline of software delivery — every rule lives in version control, ships with test data, and carries an owner and an expected true-positive rate.

Coverage is then measurable. Mapping detections to adversary techniques shows where the SOC is blind, and, just as usefully, where five overlapping rules are all firing on the same behaviour.

Our SIEM / SOC Blueprint course walks a cohort through building this pipeline from an empty repository: rule schema, unit tests against replayed telemetry, and a triage runbook that a new analyst can follow on their first shift.
