Splunk setup for Workbench

  • Updated

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

Step 1: Enable console access

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.

Note

Expel secures all login information our SOC analysts need about your devices in a MFA password product. Access to this login information is protected using our internal MFA processes. To learn more about the IP addresses all Expel traffic comes from, go here.

  1. Log into Splunk.

  2. Navigate to Settings > Access Controls > Users.

  3. Click the +Add new button.

  4. Fill in the following information:

    • For Name type Expel.

    • For Full name type Expel SOC.

    • For Email address type soc@expel.io.

    • Set the Password.

    • For Time Zone select GMT (or UTC).

    • For Assign roles select User.

    • Clear Require password change on first login.

  5. Click Save.

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 Expel Assembler.

  3. Fill in the following information:

    mceclip2.png

    • 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.

  5. You can provide console access now or set it up later. Use the instructions below to set it up later.

You can see if the device is healthy on the Security Devices page. It may take a few minutes to see the device listed as healthy.

To check if alerts are coming through, navigate to the Alerts Analysis page. Scroll to the device you want to check and click View alerts. Switch to grid view, then check the list for device alerts. It can take 36 to 72 hours for alerts to appear after setup, as we tune your device.

Step 3: Edit the device to add console access

Expel needs console access to your device to allow our SOC analysts to dig deeper during incident investigations. Additionally, our engineering teams use this access to investigate potential health issues, including proper alert ingestion.

Note

Expel secures all login information our SOC analysts need about your devices in a MFA password product. Access to this login information is protected using our internal MFA processes. To learn more about the IP addresses all Expel traffic comes from, go here.

  1. Open Workbench. Go to Organization Settings > Security Devices. Next to the device you just connected, click the down arrow and click Edit.

  2. In the Console Login area, type these details:

    • Console URL: type the console URL from the Server address in the Connection Settings area above. At the end of the URL, type /login.

    • Username: type the user name you created above.

    • Password: type the password you created above.

    • Two-factor secret key (32-character code): depending on how your organization enforces log-ins, this field may not apply to you. In these cases, you can leave it blank. This field is optional and if you have questions or concerns, reach out to your engagement manager or to support.

  3. Click Save.
