Manage detection alerts

The Alerts page displays all detection alerts. From the Alerts page, you can filter alerts, view alerting trends, change the status of alerts, add alerts to cases, and start investigating and analyzing alerts.

The Alerts page offers various ways for you to organize and triage detection alerts as you investigate suspicious events. You can:

[beta] This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features. You can group alerts by rule name, host name, user name, source IP address, or any other field. Select Group alerts by, then select an option or Custom field to specify a different field.

Each group displays information such as the alerts' severity and how many users, hosts, and alerts are in the group. The type of information displayed varies depending on the selected field.

To interact with grouped alerts:

Use the toolbar buttons in the upper-left of the Alerts table to customize the columns you want displayed:

Click the Full screen button in the upper-right to view the table in full-screen mode.

Use the view options drop-down in the upper-right of the Alerts table to control how alerts are displayed:

From the Alerts table or the alert details flyout, you can:

You can set an alert’s status to indicate whether it needs to be investigated (Open), is under active investigation (Acknowledged), or has been resolved (Closed). By default, the Alerts page displays open alerts. To filter alerts that are Acknowledged or Closed, select the appropriate status in the upper-left corner of the Alerts page. This filters all of the results displayed on the page (the Count table, Trend histogram, and Alerts table).

To change an alert’s status, do one of the following:

You can add exceptions to the rule that generated an alert directly from the Alerts table. Exceptions prevent a rule from generating alerts even when its criteria are met.

To add an exception, click the More actions menu (…​) in the Alerts table, then select Add exception. Alternatively, select Take action → Add rule exception in the alert details flyout.

For information about exceptions and how to use them, refer to Add and manage exceptions.

Suppose the rule that generated the alert uses a Timeline template. In this case, when you investigate the alert in Timeline, the dropzone query values defined in the template are replaced with their corresponding alert values.

Example

This Timeline template uses the host.name: "{host.name}" dropzone filter in the rule. When alerts generated by the rule are investigated in Timeline, the {host.name} value is replaced with the alert’s host.name value. If the alerts’s host.name value is Windows-ArsenalFC, the Timeline dropzone query is host.name: "Windows-ArsenalFC".
