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 with AuthPoint.

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

In AuthPoint, users can belong to more than one group. For users that belong to more than one group, in Splunk you must configure SAML groups with the same name as the groups in AuthPoint. Your Splunk SAML user will bind with your Splunk SAML groups.

This integration was tested with Splunk Enterprise on-premise v8.2.4

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 Certificate Management page in the AuthPoint management UI. After 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 select an account from Account Manager.
  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. If you do not have a certificate, or if all of your certificates have expired, click Add Certificate and use the newly created certificate.

    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 Enterprise as an administrator.
  2. Select Settings > Users And Authentication > Authentication Methods.

  1. Click Apply.
  2. 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.
  3. In the Entity ID text box, type a friendly name. In our example, we type Splunk.
  4. In the Advanced Settings section, from the Name Id Format drop-down list, select Email Address.
  5. In the Fully qualified domain name or IP of the load balancer text box, type the FQDN or the IP of the load balancer.
  6. In the Redirect port - load balancer port text box, type the port.
  7. Leave the default value for other settings.

  1. Click Save.

Configure AuthPoint

Before AuthPoint can receive authentication requests from Splunk, you must add a SAML resource in AuthPoint. You must also create a Zero Trust authentication policy for the Splunk resource to determine which users can authenticate and log in to Splunk and which authentication methods they can use (Push, QR code, and OTP).

Add a SAML Resource in AuthPoint

From the AuthPoint management UI:

  1. From the navigation menu, select Resources. Click Add Resource.
    The Add Resource page opens.

  1. From the Type drop-down list, select SAML.
    Additional fields appear.

  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 or paste the entityID value in the Splunk metadata file.
  4. In the Assertion Consumer Service text box, type or paste the AssertionConsumerService Location value in the Splunk metadata file.
  5. From the User ID sent on redirection to service provider drop-down list, select Email.
  6. In the Logout URL text box, type or paste the SingleLogoutService Location value in the Splunk metadata file.
  7. From the Signature Method drop-down list, select SHA-256.
  8. From the AuthPoint Certificate drop-down list, select the AuthPoint certificate to associate with your resource. This must be the same certificate that you downloaded the metadata for in the previous section.
  9. Click Save.

Add a Group in AuthPoint

You must have at least one user group in AuthPoint to configure MFA. If you already have a group, you do not have to add another group.

To add a WatchGuard Cloud-hosted group to the WatchGuard Cloud Directory:

  1. Go to Configure > Directories and Domain Services.
  2. Click the WatchGuard Cloud Directory domain name. If you have not yet added the WatchGuard Cloud Directory, click Add Authentication Domain and select the WatchGuard Cloud Directory.
    The New Group page appears.

Screenshot that shows the Directories and Domain Services page.

  1. In the Groups tab, click Add Group.
  2. In the Group Name text box, type a descriptive name for the group.
  3. (Optional) In the Description text box, type a description of the group.

  1. Click Save.
    Your group is added to the WatchGuard Cloud Directory and to AuthPoint.

Add a Zero Trust Authentication Policy

Zero Trust policies specify which resources users can authenticate to and which authentication methods they can use (Push, QR code, and OTP).

You must have at least one Zero Trust authentication policy that includes the Splunk resource. If you already have Zero Trust authentication policies, you do not have to create a new authentication policy. You can add this resource to your existing authentication policies.

Users that do not have an authentication policy for a specific resource cannot authenticate to log in to that resource.

To configure a Zero Trust authentication policy:

  1. Go to Configure > Zero Trust. If you have a Service Provider account, you must select an account from Account Manager.
  2. Click Add Policy.
  3. Type a name for this policy.
  4. In the Target section, from the Content drop-down list, select which groups this policy applies to. You can make multiple selections to add multiple groups.
  5. In the Resources section, select the AuthPoint resources this policy applies to.
  6. In the Conditions section, select the conditions that apply to this policy. When you add a condition to an authentication policy, the policy applies only to user authentications that match the policy and the policy conditions. For example, if you add a Network Location to a policy, the policy only applies to user authentications that come from that Network Location. Users who only have a policy that includes a Network Location do not get access to the resource when they authenticate outside of that Network Location (because they do not have a policy that applies, not because authentication is denied). For more information, go to About Zero Trust Conditions.
    1. (Optional) To create a new condition, click Add New Condition. After you create a new condition, you must still add the condition to the policy.
    2. From the Type drop-down list, select the type of condition to add to the policy.
    3. From the Name drop-down list, select which condition of the chosen type to add to the policy.
    4. To add more conditions, repeat Step 6.

      If you add conditions to a policy, we recommend that you create a second policy for the same groups and resources without the conditions. Assign a higher priority to the policy with the policy objects. For more information about priority, go to About Zero Trust Policy Precedence.

  7. In the Action section, select an option to specify whether to allow or deny authentications for the resources in this policy. In our example, we want to allow authentications.
    • Allow — Allow user groups in this policy access to the resources associated with this policy.
    • Deny — Deny authentications when users in the groups associated with this policy try to authenticate to the resources associated with this policy.
  8. If you allow access with this policy, select the check box for each authentication option users can select when they authenticate to resources in this policy with MFA.

    For SAML resources, if you select more than one authentication option, users must select 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.

  9. Click Save.
    Your policy is created and added to the end of the policy list.
  10. Review the order of your policies and adjust as necessary. For more information about priority, go to About Zero Trust Policy Precedence.

Add Users to AuthPoint

Before you assign users to a group, you must add the users to AuthPoint. There are two ways to add AuthPoint user accounts:

  • Sync users from an external user database
  • Add WatchGuard Cloud-hosted AuthPoint users

Each user must be a member of a group. You must add at least one group before you can add users to AuthPoint.

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. Click Send Push.
  5. Approve the authentication request that is sent to your mobile device.
    You are logged in to Splunk.
