Cb Defense Splunk Add-On 2.0.1 Released

Posted on March 20, 2018

The Carbon Black Developer Network is proud to announce the second major public release of our Cb Defense Add-On for splunk. This add-on is available for download now from Splunkbase and integrates Splunk with your Cb Defense console, forwarding alerts from Cb Defense right into your Splunk instance.

This add-on is now compatible with both Splunk on-premise and Splunk cloud.


This Add-On requires Cb Defense and Splunk version 6.6 or above.

No additional hardware requirements are necessary for running this Add-On above the standard requirements for both Carbon Black and Splunk.

Getting Started

The App can be downloaded from Splunkbase, and then manually installed on a Splunk instance - or installed directly from within the Splunk UI by logging into Splunkbase and searching for the CB Defense Add-On for Splunk.

Once the Cb Defense Add-On for Splunk is installed, then you must configure it to connect to your Cb Defense server. This is done by generating a “SIEM” connector key in the Cb Defense console. For information on how to generate API keys, see the Cb Developer Network. Ensure that your new Connector key is of type “SIEM”.

Next, add “notification” rules to your Cb Defense server. Navigate to the “Settings -> Notifications” page and click the “Add Notification” button. Make sure to add the connector key name you set up above into the list of subscribed connectors in the text box at the bottom of the notification rule dialog box.

If you are working from a Splunk instance with a UI you can use the web-UI to configure the Add-on quite simply. See below for instructions on how to configure the Add-on from the CLI - for instance when deploying to a forwarder.

To configure the Cb Defense Add-on for Splunk to connect to your Cb Defense server:

GUI Configuration

  1. Start the Cb Defense Add-on in Splunk
  2. Go to the “Inputs” tab - “Create new input” page and fill in the following fields:
    1. Enter the API hostname for your Cb Defense instance in the URL field. Example: api-url.conferdeploy.net. Refer to: Cb Defense API Basics.
    2. Set apikey to your API key and the connector ID to your connector ID
    3. Set “name” to anything (for example “cbdefense”)
    4. Set “interval” to 60 seconds (the polling interval of the Cb Defense notifications API)
    5. Set “index” to whatever Splunk index you’d like the Add-On to place Cb Defense events into

The 2.X Add-on for Splunk supports as many rest-inputs as a user desires. If you would like to integrate with multiple Cb Defense Servers/Connectors simply define multiple inputs.

The Cb Defense Add-On for Splunk uses Splunk’s encrypted credential storage facility to store the API token for your Cb Defense server, so the API key is stored securely on the Splunk server.

CLI Configuration

The Cb Defense Add-on for Splunk can also be configured through the CLI:

1) Manually install the Add-on, by unarchiving the Add-on into $SPLUNK_HOME/etc/apps , restarting Splunk service.

2) Create a $SPLUNK_HOME/etc/apps/TA-Cb_Defense/local/inputs.conf like this:

cb_defense_api_url = <ip or hostname of CB Defense>
interval = <Interval to poll the notifications API at >
siem_api_key = <API KEY>
siem_connector_id = <connector ID>

Once again, you can define multiple stanzas in the inputs.conf to integrate with multiple Cb Defense Servers/Connectors.
