Tip

This article was accurate at the time of writing, but changes happen. If you find the instructions are outdated, leave a description in the comment field below and let us know!

Having read-only access to the interface of your technology allows Expel to dig deeper during incident investigations. Our device health team uses this access to investigate potential health issues with your tech.

By following these steps, you create a user account for Expel that keeps the Expel activity separate from other activity on the Splunk console.

Note

Expel needs access to the Splunk device or instance through port 8000 (UI) and 8089 (API). For cloud instances, follow the Splunk Configure IP Allow List instructions to grant Expel these access privileges:

  • Search head API access

  • Search head UI access

Expel has 6 egress IP addresses. All requests to rest API come from 1 of 6 IP addresses. We’ve designed this so it can scale significantly without Expel needing to add new IP addresses to the list.

  • 34.75.13.114/32

  • 34.75.152.7/32

  • 35.243.190.98/32

  • 104.196.158.205/32

  • 34.75.81.28/32

  • 34.75.210.18/32

Tip

After console access is established for Expel, the remaining onboarding steps for this technology can also be performed by Expel. Reach out to your engagement manager if this is needed and we're happy to complete the integration!

Step 2: Configure the technology in Workbench

Now that we have the correct access configured and noted the credentials, we can integrate your tech with Workbench.

  1. Go to https://workbench.expel.io/settings/security-devices?setupIntegration=splunk.

  2. If your installation is on premises (On-prem), then select the Assembler connected to the Splunk device. This is the assembler you set up in How to provision Wazuh Assembler.

  3. Fill in the following information:

    • Name: the hostname of the Splunk device.

    • Location: the geographic location of the appliance.

    • Username: the username created in Step 1.

    • Password: the password created in Step 1.

    • Leave the Splunk Enterprise Security instance? field blank.

      Note

      Integration_Vendors: Splunk Enterprise Security alerts require review by Expel before enabling. Reach out to your engagement manager for details.

    • Server address:

      • Cloud: type the Splunk server address and port 8089. For example: https://<domainname>.splunkcloud.com:8089.

      • On-prem: type the Splunk console IP address and port 8089. For example: https://10.10.10.10:8089/.

  4. Click Save.

To check if alerts are coming through, navigate to Alerts on the console page. Click the icon in the upper right to switch to grid view, then check the list for device alerts.
