description: 'Data Components represent specific types of observable events or artifacts
  within a Data Source that can be collected to detect adversary technique execution.
  For example, ''Process Creation'' and ''Process Termination'' are data components
  within the ''Process'' data source.

  Data Components serve as the bridge between defensive telemetry and ATT&CK techniques.
  They detect techniques via ''detects'' relationship objects.

  The x_mitre_log_sources property (optional in Spec 3.x, required in Spec 4.x) provides
  platform-specific log collection configurations specifying exactly which log provider
  and event channel to monitor.

  The x_mitre_data_source_ref property establishing the parent data source link is
  DEPRECATED in ATT&CK Specification 3.3.0 and will be removed in 4.0.0.'
