NodeZero Add-on for Splunk

Splunk Cloud
Overview
Details
NodeZero™ provides continuous autonomous penetration testing as a true SaaS offering. With NodeZero, cybersecurity teams proactively find and fix internal and external attack vectors before attackers can exploit them.

This Add-on allows NodeZero users to ingest pentest results directly into Splunk, merging insights gained from the attacker's perspective with existing data and workflows in Splunk.

Pre-Requisites

NodeZero API Key

An API key is required to access the API. The key is tied to an existing user account with Org Admin privileges in the Horizon3.ai portal.
(At this time, API keys are manually provisioned by Horizon3.ai. If you don’t have an API key, please contact your Horizon3.ai representative to acquire one.)

Setup

Save API Key to Splunk credential store

On the Configuration page, click the Add button on the Accounts sub-tab

  • Name is a simple name that gets used by the Inputs page
  • Description is for any notes/details about the API Key/Account
  • API Key is an encrypted field for saving the NodeZero API Key

Create the Input

On the 'Inputs' tab, click "Create New Input"

  • Name (required) is a simple name that gets used by the modular input
  • Description (optional) is for any notes about the modular input
  • API Account (required) is a dropdown single select to choose the account for which you wish to pull data
  • Index (required) the index to which you would like to ingest NodeZero data
  • Polling Interval (optional) Default is 86400 seconds (daily). How frequently you want to poll for new data

Once the input is saved, it immediately begins attempting to pull data from the NodeZero API

Verify data is being indexed

To make sure the modular input is doing its job, you can run the following search:

index=<index_you_chose_for_input> sourcetype=h3* | stats values(sourcetype) as st

You should see three sourcetypes:

h3:nodezero:api:action_logs
h3:nodezero:api:host_export_csv
h3:nodezero:api:weakness_export_csv

There is also a non-navigable dashboard at /en-US/app/TA_nodezero/kvstore_state that will show a table based on the KVstore the modular input uses to store app state. This can be used during troubleshooting to see what data has been pulled for each pentest.

Troubleshooting

For troubleshooting information, view ExecProcessor logs and the nodezero logs:

    index=_internal (sourcetype=splunkd nodezero component=ExecProcessor) OR sourcetype="*nodezero*"

Note: Don't forget the asterisks for sourcetype=*nodezero*, as it often shows as either ta_nodezero-too-small or ta_nodezero.

For more logs: set LOGGING to DEBUG in the Configuration tab

Support

Email splunk@horizon3.ai with any questions, comments, or concerns. Feedback is greatly appreciated!
