description: 'Detection Strategies define high-level, platform-agnostic approaches
  for detecting specific adversary techniques. They function as containers organizing
  one or more platform-specific Analytics (x-mitre-analytic objects) into cohesive
  detection methodologies, describing what data to collect and what behavioral patterns
  to look for.

  Detection Strategies were introduced in ATT&CK Specification 3.3.0 as part of the
  new detection framework, superseding the deprecated x-mitre-data-source and x-mitre-data-component
  approach for technique detection.

  A Detection Strategy links to its implementing analytics via x_mitre_analytic_refs.
  Analytics in turn link back to data components via x_mitre_log_source_references,
  creating a complete detection chain from technique to observable log event.'
