You can configure detection alert settings that monitor when a detection has occurred on specific protocols. When the conditions configured in the alert settings are met, the ExtraHop system generates a detection alert, which you can view in the Alert History.
|Note:||This topic applies to all ExtraHop systems, including ExtraHop Reveal(x).|
Detection alerts are useful for monitoring unusual behavior that you want to be notified of right away. For example, if you are worried about spikes in SSH sessions on specific servers, you can configure alert settings to watch for detections that occur over SSH and assign the alert configuration to SSH servers.
- Log into the Web UI on the ExtraHop Discover or Command appliance.
- Click the System Settings icon and then click Alerts.
- Click New to open the Alert Configuration window.
- Enter a unique name for the alert configuration in the Name field.
- From the Alert Type section, click Detection.
Click the Source Type list and select the data source
for the alert configuration.
The alert configuration can be assigned only to the type of source selected.
Select one of the following detection categories:
Option Description Any category Watches for detections on assigned sources that occur over any detection category. Specific categories Watches for detections on assigned sources that occur only within specified detection categories.
Click Select Categories to specify one or more categories. If you select Security, all security detection categories will apply. If you select IT Operations, all performance detections will apply.The type of detection categories vary by your ExtraHop system. Security detections are only available for ExtraHop Reveal(x). Learn more in Detections.
Select one of the following protocols options:
Option Description Any protocol Watches for detections on assigned sources that occur over any protocol. Specific protocols Watches for detections on assigned sources that occur only over specified protocols.
Click Select Protocols to specify one or more categories, such as HTTP Client and HTTP Server.
Select one of the following firing modes:
Option Description Edge-Triggered Generates an alert only once when the alert conditions are true. The alert is generated again only if conditions are true after the metric value has returned to normal conditions twice. Level-Triggered Generates alerts continuously while the alert conditions are true for the specified time period.
