In this topic, you will find general instructions on how to integrate Splunk Cloud with Portnox™ Zero Trust Network Access.

Create a Portnox Cloud application configuration

In this step, you will create a configuration in Portnox Cloud that will contain all the information necessary to integrate with Splunk Cloud.

  6. Keep this browser tab open. You will need it later.

Open your Splunk Cloud SAML configuration

In this section, you will access your Splunk Cloud administrative interface and find the SAML configuration page.

  1. In another tab of your browser, open your Splunk Cloud web interface by accessing the following URL: https://your_tenant.splunkcloud.com/, substituting your_tenant with your Splunk Cloud tenant name.

  2. In the top menu, click on the Settings option to open the menu, and then in the USERS AND AUTHENTICATION section, select the Authentication methods option.

  3. In the Authentication methods pane, in the External section, select the SAML option, and then click on the Configure Splunk to use SAML link.

Export metadata from the Portnox tab and upload it in the Splunk tab

In this section, you will export the metadata from Portnox Cloud into a file and upload that file in the Splunk Cloud SAML configuration section.

  2. In the Splunk tab, click on the Select File button next to the Metadata XML file heading, and then upload the XML file downloaded from Portnox Cloud.

  3. In the Splunk tab, in the Entity ID field, enter https://your_tenant.splunkcloud.com/, substituting your_tenant with your Splunk Cloud tenant name.

    1. Click on the OPTIONAL SETTINGS link to show additional fields, and then in the Application Login URI field, enter the following value: https://your_tenant.splunkcloud.com.
      Note:
      This step is required if you want to show this application in the ZTNA Secure Access Portal.

    2. Optional: Click on the Next button, and in the Policy enforcement section, in the Device risk assessment section, change the setting to Override with custom policy and then select a risk assessment policy if you want to assess risk with this application using a custom risk assessment policy, and in the Access control section, change the setting to Override with custom policy and then select an access control policy if you want to control access to this application using a custom access control policy.
      Note:
      To configure the access control policy, follow the steps in this topic: Create or edit an access control policy. To select the default access control policy, on the Groups screen, select a group that you want to configure the default for, click on the  ⋮  icon at the end of the row that represents the group, and then select the Group policies option. Then, in the ZTNA Resources section, select the policy in the SSO Web resources drop-down menu.
    3. Scroll all the way down to the end of the page, and then click on the Add resource button.

  2. Finalize the SAML configuration in the Splunk tab.
    1. In the Name Id Format field, select the Email Address option.

    2. In the SSO Binding section, click on the HTTP Post button.

    3. In the Alias section, in the Role alias field, paste the following value: http://schemas.microsoft.com/ws/2008/06/identity/claims/role.

    4. Click on the Save button.

  3. Configure your identity provider to send group information in the role field.

    For example:

    • If you use Entra ID: In the Attributes & Claims pane, click on the Add a group claim button. In the Group Claims pane, select All groups, set Source attribute to Group ID, in the Advanced options section, activate the Customize the name of the group claim checkbox, activate the Emit groups as role claims checkbox, and then click on the Save button.

    • If you use Google Workspace: In the SAML attribute mapping pane, add all Google groups that you want to have access to Splunk Cloud, and in the App attribute field, enter role. Then, click on the Save button.

  4. Map SAML groups in the Splunk tab.
    1. In the SAML Groups pane, click on the New Group button.

    2. In the Create New SAML Group window, in the Group Name field, enter the group identifier as used in your identity provider, select suitable Splunk Roles for this group, and then click on the Save button.

      Note:
      For example, in Entra ID, the group-name-as-in-your-identity-provider is the Object ID displayed on the group screen (in the UUID format, for example, 1b6c91ce-18d9-4211-8052-cc749bd73dd2), and in Google Workspace, it is the username part of the group’s email address (for example, administrators).

Result: You have configured Splunk Cloud to be accessible using Portnox Zero Trust Network Access.

Note:
If you made an error configuring Zero Trust Network Access and you cannot use SAML to log in to Splunk Cloud, you can log in to Splunk Cloud with your Splunk credentials using the following URL: https://your_tenant.splunkcloud.com/en-US/account/login?loginType=splunk, where your_tenant is your Splunk Cloud tenant name.
