About building block rules

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 (.alerts-security.alerts-<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.

To create a rule that searches alert indices, select Index Patterns as the rule’s Source and enter the index pattern for alert indices (.alerts-security.alerts-*):

By default, building block alerts are excluded from the Overview and Alerts pages. You can choose to include building block alerts on the Alerts page, which expands the number of alerts.

1. Find Alerts in the navigation menu or by using the global search field.
2. In the Alerts table, select Additional filters > Include building block alerts, located on the far-right.
