Description
The ExtraHop Detection SIEM Connector supports ExtraHop integrations with security information and event management systems (SIEMs) by formatting and transmitting detection data over syslog. This bundle sends messages in LEEF 2.0 or CEF formats and can be accepted by any SIEM or system that accepts syslog input.
Note that if you install this bundle on a Command appliance, you must configure ODS Syslog targets for each connected Discover appliance and modify the trigger included in the bundle.
This bundle is required for the following third-party applications: * ExtraHop App for QRadar (LEEF) * ExtraHop Data Connector for Azure Sentinel (CEF)
This bundle can optionally send detection information to Splunk through the ExtraHop Add-On for Splunk and the LEEF connector trigger.
Requirements
- You must have an ExtraHop Discover or Command appliance with firmware version 7.8 or later with a user account that has Unlimited (administrator) privileges
- You must have access to a SIEM system that accepts syslog input
Installation Instructions
Install the bundle
- Download the bundle on this page.
- Upload and apply the bundle.
Configure ODS targets for Discover appliances
- Log into the Admin UI on each Discover appliance.
- Configure an open data stream for syslog with the following parameters:
- Name: A name to identify the SIEM server.
- Host: The hostname or IP address of your SIEM server.
- Port: 514.
- Protocol: TCP or UDP.
- The Local Time checkbox should not be selected.
- Name: A name to identify the SIEM server.
Configure the trigger
- In the Web UI on the Command or Discover appliance where you installed the bundle, click the System Settings icon, and then click Triggers.
- In the list of triggers, click ExtraHop Detection SIEM Connector - CEF or ExtraHop Detection SIEM Connector - LEEF.
- Click the Editor tab.
Change the default string value in the "ods_syslog_targets" array from "target1" to the name of the ODS target. If there are multiple configured ODS targets for this trigger, you can add them as a comma-delimited list of strings in the "ods_syslog_targets" array, similar to the following example:
const ods_syslog_targets = ["myTarget", "myTarget2"];
Type the hostname or IP address of the Command or Discover appliance into the "hostname" variable, similar to the following example:
const hostname = "host.example.com";
Click Save and Close.
Select the checkbox next to the ExtraHop Detection SIEM Connector trigger you modified and then click Enable.
