Palo Alto Networks GlobalProtect Integration with AuthPoint

Deployment Overview

This document describes how to set up AuthPoint multi-factor authentication (MFA) for Palo Alto Networks GlobalProtect. GlobalProtect must already be configured and deployed before you set up MFA with AuthPoint.

Palo Alto Configuration for RADIUS Authentication

AuthPoint communicates with various cloud-based services and service providers with the RADIUS protocol. This diagram shows an overview of the configuration required for RADIUS authentication.

Before You Begin

Before you begin these procedures, make sure that:

• You have finished the initial configuration of your Palo Alto PA-220
• You have installed the Palo Alto GlobalProtect in your client PC
• A token is assigned to a user in AuthPoint

We recommend that you install the AuthPoint Gateway. For more information, see About Gateways.

Configure AuthPoint

Before AuthPoint can receive authentication requests from GlobalProtect, you must:

• Specify GlobalProtect as a RADIUS client resource In AuthPoint, resources are the applications and services that your users connect to. in AuthPoint.
• Add an authentication policy Authentication policies specify which resources users can authenticate to and which authentication methods they can use (Push, QR code, and OTP). for the GlobalProtect RADIUS client resource or add the GlobalProtect RADIUS client resource to an existing authentication policy.
• Bind the GlobalProtect RADIUS client resource to the AuthPoint Gateway.

Add a RADIUS Resource in AuthPoint

From the AuthPoint management UI:

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

2. From the Type drop-down list, select RADIUS Client.
   Additional fields appear.

3. On the RADIUS Client page, in the Name text box, type a name for this resource.
4. In the RADIUS client trusted IP or FQDN text box, type the Palo Alto internal interface IP address.
5. In the Value sent for RADIUS attribute 11 (Filter-Id) drop-down list, select User's AuthPoint group.
6. In the Shared Secret text box, type the shared secret that you configured in the Configure RADIUS Service section.

7. 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 group to AuthPoint:

1. From the navigation menu, select Groups.
2. Click Add Group.
   The New Group page appears.

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

5. Click Save.
   Your group is listed on the Groups page.

Add an Authentication Policy to AuthPoint

Authentication policies specify which resources users can authenticate to and which authentication methods they can use.

You must have at least one authentication policy in AuthPoint that includes the GlobalProtect RADIUS client resource. If you already have 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 an authentication policy:

1. From the navigation menu, select Authentication Policies.
   The Authentication Policies page opens.

2. Click Add Policy.
   The Add Policy page opens.

3. In the Name text box, type a name for this policy.
4. From the Select the Authentication Options drop-down list, select Authentication Options, then select which authentication options users can choose from when they authenticate.

   If you enable the push and OTP authentication methods for a policy, RADIUS client resources associated with that policy use push notifications to authenticate users.

   QR code authentication is not supported for RADIUS client resources.

5. From the Groups drop-down list, select which groups this policy applies to. You can select more than one group. To configure this policy to apply to all groups, select All Groups.
6. From the Resources drop-down list, select the resource that you created in the previous section. If you want this policy to apply to additional resources, select each resource this policy applies to. To configure this policy to apply to all resources, select All Resources.

7. (Optional) If you have configured policy objects such as a Network Location, select which policy objects apply to this policy. When you add a policy object to a policy, the policy only applies to user authentications that match the conditions of the policy objects. 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 RADIUS authentication, policies that have a Network Location do not apply because AuthPoint does not have the IP address of the user.

   If you configure policy objects, we recommend that you create a second policy for the same groups and resources without the policy objects. The policy with the policy objects should have a higher priority.

8. Click Save.
   Your policy is created and added to the end of the policy list.

   When you create a new policy, we recommend that you review the order of your policies. AuthPoint always adds new policies to the end of the policy list.

Bind the RADIUS Resource to a Gateway

To use RADIUS authentication with AuthPoint, you must have the AuthPoint Gateway installed on your corporate network and you must assign your RADIUS resources to the Gateway in the AuthPoint management UI. The Gateway functions as a RADIUS server.

If you have not already configured and installed the AuthPoint Gateway, see About Gateways.

To assign your RADIUS resources to the Gateway:

1. From the navigation menu, select Gateway.
2. Select the Name of the Gateway.

3. From the RADIUS section, in the Port text box, type the port number used to communicate with the Gateway. The default ports are 1812 and 1645.

   If you already have a RADIUS server installed that uses port 1812 or 1645, you must use a different port for the AuthPoint Gateway.

4. From the Select a RADIUS Resource drop-down list, select your RADIUS client resource.
5. Click Save.

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 local 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 Palo Alto GlobalProtect, you can authenticate with a token on your mobile device. For RADIUS resources, you authenticate with a one-time password (OTP) or a push notification. The authentication method you use is determined by the access policy for your RADIUS client resource.

If you enable the push and OTP authentication methods for a policy, RADIUS resources associated with the policy use push notifications to authenticate users.

In this example, we show the OTP authentication method (users append the OTP for their token to their password).

1. Downlaod the GlobalProtect App and install it, refer to https://docs.paloaltonetworks.com/globalprotect/5-1/globalprotect-app-user-guide.
2. Install the two certificates that you exported before.
3. Start the GlobalProtect App.

   

4. Type the IP address of your Palo Alto ethernet1/1 interface. Click Connect.

   

5. In the Username text box, type your AuthPoint user name.
6. In the Password text box, type your password and the OTP for your token (shown in the AuthPoint mobile app). Do not add a space between your password and your OTP.

   

7. Click Connect.
