Splunk Integration with AuthPoint

Deployment Overview

This document describes how to set up multi-factor authentication (MFA) for Splunk® with AuthPoint as an identity provider. Splunk must already be configured and deployed before you set up MFA withI've AuthPoint.

Splunk can be configured to support MFA in several modes. For this integration, we set up SAML with AuthPoint.

This integration was tested with Splunk Enterprise on-premise v7.2.

Splunk Authentication Data Flow with AuthPoint

AuthPoint communicates with various cloud-based services and service providers with the SAML protocol. This diagram shows the data flow of an MFA transaction for Splunk.

Before You Begin

Before you begin these procedures, make sure that:

Configure Splunk

To start, you must download the metadata file from the Resources page in the AuthPoint management UI. Once you have the metadata file, you can configure Splunk.

  1. Log in to WatchGuard Cloud.
  2. From the navigation menu, select Configure > AuthPoint. If you have a Service Provider account, you must first pivot to your Subscriber view.
  3. Select Resources.
  4. Click Certificate.

  1. Next to AuthPoint certificate you will associate with your resource, click and select Download Metadata.

    We recommend that you choose the certificate with the latest expiration date.

    The AuthPoint metadata provides your resource, in this case Splunk, with information necessary to identify AuthPoint as a trusted identity provider.

  1. Log in to Splunk as an administrator.
  2. Select Settings > Access controls.

  1. Click Authentication method.

  1. For the External authentication method, select SAML.
  2. Click SAML Settings.

  1. Click SAML Configuration.

  1. Next to Metadata XML File, click Select File and upload the AuthPoint metadata file that you downloaded.
  2. Click Apply.

  1. In the General Settings section, in the IdP certificate path text field type the path to your IdP certificate. If you store it in the default location, type the name of the certificate.
  2. In the Entity ID text box, type a friendly name. In our example, we type Splunk.

  1. In Advanced Settings section, from the Name Id Format drop-down list, select Email Address.
  2. Type the FQDN or the IP of the load balancer. The host itself is OK.
  3. For SSO Binding, select HTTP Redirect.
  4. For Signature Algorithm, select SHA256.
  5. For SLO Bindings, select HTTP Redirect.
  6. Click Save.

  1. Click SAML Configuration again.
  2. Next to SP Metadata File, click Download File.
  3. On the SAML Groups page, click New Group.
  4. Type a Group Name.
  5. Select the Splunk Roles to use for authentication.
  6. Click Save.

Configure AuthPoint

Before AuthPoint can receive authentication requests from Splunk, you must specify the Splunk client as a resource in AuthPoint. You must also assign the Splunk resource to the user group that will authenticate through Splunk.

Add a SAML Resource in AuthPoint

From the AuthPoint management UI:

  1. From the navigation menu, select Resources.
  2. From the Choose a Resource Type drop-down list, select SAML. Click Add Resource.

  1. On the SAML page, in the Name text box, type a name for this resource.
  2. From the Application Type drop-down list, select Splunk.
  3. In the Service Provider Entity ID text box, type Splunk. You can copy this value from the Splunk metadata file.
  4. In the Assertion Consumer Service text box, type http://<fqdn or ip>/saml/acs. You can copy this value from the Splunk metadata file.
  5. Click Save.

Add an Access Policy to AuthPoint

You must have at least one user group in AuthPoint for authentication with Splunk, and you must assign an access policy for the Splunk resource to that group. If you already have a group, you do not have to add another group.

In the AuthPoint management UI:

  1. From the navigation menu, select Groups.
  2. To add a new group, click Add Group. If you already have a group that you want to use, select the group to edit it.

  1. In the Name text box, type a descriptive name for the group.
  2. (Optional) In the Description text box, type a description of the group.

  1. In the Access Policy section, click Add Policy.

  1. In the Add Policy dialog box, from the Resource drop-down list, select the resource you want to add an access policy for.
  2. (Optional) To require that users type their password before they authenticate for this resource, select the Require Password Authentication toggle.
  3. Select the authentication options that users in this group can choose from when they authenticate.

    For SAML resources, if you select more than one authentication option, users must choose one of the available options when they authenticate. For example, if you select OTP and Push, users can choose to type their OTP or approve a push to authenticate. You cannot require that they do both.

  1. Click Add.

  1. (Optional) Add one or more safe locations to your group. For more information about safe locations and detailed instructions to add them, see About Safe Locations.
  2. Click Save.

Before you assign users to a group, you must add them to AuthPoint. You can manually add user accounts or import user accounts from your LDAP database. For more information on how to add user accounts, see Add User Accounts.

Test the Integration

To test AuthPoint MFA with Splunk, you can authenticate with a mobile token on your mobile device. You can choose any method (one-time password, QR code, or push).

In this example, we show the push authentication method (users receive a push notification in the mobile app that they must approve to authenticate).

  1. In a web browser, go to the Splunk URL.
  2. Type your email address or AuthPoint user name. Click Next.
  3. If required, in the Password text box, type your password.
  4. For the authentication method, select Push.
  5. Click Send.
  6. Approve the authentication request that is sent to your mobile device.
    You are logged in to Splunk.
