Designing how Kestrel Home Retail handles threat-intelligence indicators on the indicator lifecycle board: eight sources, from the Stratafeed commercial feed to Kestrel's own incident findings, against eight handling stages — ingest, validate, enrich, score, deploy, hit, review and expire — with 41 of the 64 tiles now controlled; the incident that started it, when an unvalidated automatic sync blocked 41 addresses in the payment provider's shared CDN and stopped checkout for three hours while a real phishing hit waited nine days behind 40,000 stale indicators; and the result, with the true-positive rate up from 0.2% to 14%, alerts down from 1,310 to 96 a week and rollback cut from three hours to six minutes.

Threat Intelligence Indicator Handling Scenario Design

An expert-level course on designing how an organisation handles indicators of compromise so that they improve detection instead of flooding it - requirements first, sources graded, indicators validated against what must never be blocked, enriched passively, scored and decayed by type, deployed with owners and rollback, shared under handling rules, retired on time and measured by what they find. Work across the Indicator Lifecycle Board, eight sources against eight handling stages, and build a single Indicator Handling Standard and Source Evaluation Register as you go.

What you'll learn

  • Reconstruct an indicator-driven incident across the eight handling stages, measure a watchlist by source, age and outcome, write priority intelligence requirements and baseline a source-by-stage lifecycle board.
  • Grade sources on the Admiralty scale from sampled records, decompose aggregate feeds, rewrite commercial feed contracts around requirements and score sources by what they give back.
  • Normalise and de-duplicate indicators, build a known-good register of business dependencies, and prove validation gates on replayed real intake.
  • Define required context fields, enrich passively through licensed services, group indicators into campaigns and state confidence on a written scale.
