About building block rules

edit

Create building block rules when you do not want to see their generated alerts in the UI. This is useful when you want:

  • A record of low-risk alerts without producing noise in the Alerts table.
  • Rules that execute on the alert indices (.siem-signals-<kibana space>-*). You can then use building block rules to create hidden alerts that act as a basis for an ordinary rule to generate visible alerts.
