The Rules page

You can sort the rules by clicking the Rule, Last updated, or Enabled column header.

To sort by any other column, switch on the Technical preview toggle above the table. This experimental table view allows advanced sorting capabilities. If you experience performance issues when working with the table, you can turn this setting off.

On the Rules page, you can:

Load and activate prebuilt Elastic rulesedit

To load the Elastic Security app’s prebuilt rules, go to Detect → Rules → Load Elastic prebuilt rules and Timeline templates).

You can then activate whichever rules you want. If you delete any prebuilt rules, a button appears that enables you to reload all of the deleted ones.

Apart from the Elastic Endpoint rule, prebuilt rules are not activated by default. If you want to modify a prebuilt rule, you must first duplicate it, then make your changes to the duplicated rule. All Elastic prebuilt rules are tagged with the word Elastic.

  2. Do one of the following:

    • Edit a single rule: Select the All actions menu (…​) on a rule, then select Edit rule settings. The Edit rule settings view opens, where you can modify the rule’s settings.
    • Edit multiple rules: Select all the rules you want to edit, then select an action from the Bulk actions menu:

Export and import rulesedit

You can export detection rules to an .ndjson file, which you can then import into another Elastic Security environment. The following configuration items are also included in the .ndjson file:

  • Actions
  • Exception lists

Although detection rule actions are included in the exported file, the connectors used by the actions are not included. Use the Saved Objects UI in Kibana (Stack ManagementKibanaSaved Objects) to export and import any necessary connectors before you export and import the detection rules.

Similarly, any value lists used for rule exceptions are not included in rule exports or imports. Use the Upload value lists UI (DetectRulesUpload value lists) to export and import value lists separately.

To export and import detection rules:

  1. Go to DetectRules.
  2. To export rules:

    1. In the All rules table, select the rules you want to export.
    2. Select Bulk actionsExport, then save the exported file.

      You cannot export Elastic prebuilt rules.

  3. To import rules:

    You need at least Read privileges for the Action and Connectors feature to import rules with actions. If you’re importing rules without actions, Action and Connectors feature privileges are not required. Refer to Enable and access detections for more information.

    1. Click Import rules.
    2. Drag and drop the file that contains the detection rules.

      Imported rules must be in an .ndjson file.

    3. (Optional) Select Overwrite existing detection rules with conflicting "rule_id" to update existing rules if they match the rule_id value of any rules in the import file. Configuration data included with the rules, such as actions, is also overwritten.
    4. (Optional) Select Overwrite existing exception lists with conflicting "list_id" to replace existing exception lists with exception lists from the import file if they have a matching list_id value.
    5. Click Import rule.
