Duo Trusted Endpoints - Workspace ONE Managed Device Deployment

Overview

Duo's Trusted Endpoints feature secures your sensitive applications by ensuring that only known devices can access Duo protected services. When a user authenticates via the Duo Prompt, we'll check for the access device's management status. You can monitor access to your applications from trusted and untrusted devices, and optionally block access from devices not trusted by your organization.

Trusted Endpoints is part of the Duo Essentials, Duo Advantage, and Duo Premier plans.

Before enabling the Trusted Endpoints policy on your applications, you'll need to deploy the Duo device certificate or REST API access for Duo to your managed mobile devices, or deploy Duo Desktop to Windows and macOS managed systems and sync identifiers for those systems from Workspace ONE into Duo.

This guide walks you through Workspace ONE configuration for Windows and macOS endpoint clients and Android and iOS mobile devices.

Requirements

• Access to the Duo Admin Panel as an administrator with the Owner, Administrator, or Application Manager administrative roles.
• Access to the Workspace ONE Console as an administrator with the rights to create roles, accounts, and device profiles.
• Directory Services enabled within the Workspace ONE Console with an account in the directory that will be used as an Admin Account within Workspace ONE.

Create a Duo Admin and API Key in Workspace ONE

Create a read-only API user and role and an API key in Workspace ONE for Duo to obtain managed endpoint information. Duo will use this account to synchronize your Windows device identifiers from Workspace ONE. The imported identifiers will be used to determine device trust when Windows devices access your protected applications.

You only need to do this once, and can then use the same Duo admin credentials and API key for each Workspace ONE management integration you configure in Duo, even if they are for different device operating systems.

Create an API Role for Duo

1. Log in to the Workspace ONE console as an administrator and go to Accounts → Administrators → Roles.

2. Click the Add Role button. Enter Duo API Role as the Name and add a Description for the new role on the "Create Role" page.

3. Click on the "API" category on the left and then locate REST in the API category list. Check the box in the "Read" column to grant the new Duo API role read access to devices. Click Save to create the role.

   

Create a Duo Admin Account

Determine whether you plan to create an admin for Duo using an account synced from an external directory or a "Basic" (local) account before you begin.

We recommend using a directory account over a "Basic" account because Workspace ONE enforces password expiration for "Basic" user types every 30 days. While the password is expired, your Trusted Endpoint Integration with Workspace ONE will not work, and you will need to reset the password to restore functionality.

Use of a directory account is not subject to the 30-day password expiration.

1. Navigate to Accounts → Administrators → List View in the Workspace ONE console.

2. Click the Add button and choose Add Admin → Directory → Next on the pop-up menu.

3. Enter the following information on the "Add Admin" form (for a Directory admin):

   Admin Type	Directory
   Directory Name	Default
   Domain	Select the correct domain from the drop-down, if not already selected.
   Username	Search for an account in your directory to use and click Select User.

   

4. Click Next to go to the "Roles" tab.

5. On the "Roles" tab, choose your Organization Group from the list presented. Locate and select the "Duo API Role" read-only role you created earlier in the Role list.

   

6. Click the Next button on the "Details" page. You can optionally fill in the fields on the Details page.

7. On the “Settings“ tab, leave "Two Factor Authentication" as the default, choose None in the “Notification” section, and leave the "User Credentials" option selected in the “API” section.

   

8. Click Save to create a Directory admin.

9. Click the Add button and choose Add Admin on the pop-up menu.

10. Enter the following information on the "Add Admin" form (for a Basic admin):

    Admin Type	Basic

    Email Address	Enter an email address for the Duo admin user.
    Time Zone	Select your time zone.
    Locale	Select your language/region.
    Initial Landing Page	Leave as the default option.

    

11. Click the Next button to go to the "Roles" section, then click the Add Role button.

12. Choose your Organization Group from the list presented. Locate and select the "Duo API Role" read-only role you created earlier in the Role list.

    

13. Click the Next button on the "Details" page. You can optionally fill in the fields on the Details page.

14. Click the Next button to go to the “Settings“ section and ensure that you select the "User Credentials" option for the API.

15. On the “Settings“ tab, leave "Two Factor Authentication" as the default, choose None in the “Notification” section, and leave the "User Credentials" option selected in the “API” section.

Once your Workspace ONE managed devices receive the Duo config you can set the Trusted Endpoints policy to start checking for managed device status as users authenticate to Duo-protected services and applications.

When your trusted endpoints policy is applied to your Duo applications, return to the Workspace ONE trusted endpoint management integration in the Admin Panel. The "Change Integration Status" section of the page shows the current integration status (disabled by default after creation). You can choose to either activate this management integration only for members of a specified test group, or activate for all users. If you created more than one Workspace ONE integration, you must activate each one individually.

Duo Premier and Duo Advantage plans: The Device Insight and Endpoints pages in the Duo Admin Panel show which access devices are trusted/managed.

Verify Your Setup

iOS App Config and Android

Users with Duo Mobile installed and activated for Duo Push on Android and iOS devices see a device trust dialog when authenticating to a protected resource via the Duo Prompt.

Duo uses the API access you granted in Workspace ONE to perform a permissions check to verify device information.

If Duo successfully verifies the device information using the Workspace ONE API access, and the user has Duo Mobile activated for Duo Push, then the user receives a login request on their phone.

On Android devices, approving the request grants access and returns the user to the protected application. On iOS devices, after approving the Duo authentication request users tap the top-left of the Duo Mobile app to return to the application and complete login. The "Second Factor" logged for these approvals is shown as "Duo Mobile Inline Auth" in the Duo authentication log.

If the user does not have Duo Mobile activated for push, or does not approve the Duo request before it times out, the user returns to the Duo Prompt, where they may select from the available factors to complete 2FA.

With the legacy iOS certificate configuration, iOS users will see a prompt asking them to choose a certificate when authenticating to a protected resource via the Duo prompt. After selecting the Duo Device Authentication certificate and completing authentication, subsequent Duo authentications from the same device will automatically use that same certificate for verification.

Windows and macOS with Duo Desktop

When Windows or macOS users access Duo-protected resources, Duo Desktop provides device information to Duo. If the information from the device matches the information in Workspace ONE, Duo grants access to the trusted device.

Search for Device Identifiers

If you configured Duo Desktop for Windows or macOS or Duo Mobile for iOS with App Config or Android to determine device trust, you may want to search for specific device identifiers to verify that the identifier information for a given trusted device exists in Duo. This can be useful to verify a device you expect to be trusted was imported from Workspace ONE into Duo.

To search for a device identifier in Duo:

1. Log in to the Duo Admin Panel and navigate to Trusted Endpoints.

2. Locate the Workspace ONE, Workspace ONE with Duo Desktop, or Workspace ONE with App Config device management integration you want to search for a device identifier in the list and click on it to view its details.

3. In the Check if devices have synced section, enter the identifier for the device you want to check and click Search.

4. A message appears indicating if the device identifier was either found or not found. If the device identifier is not found, check your Workspace ONE API configuration and wait 24 hours.

Use these instructions to find the device identifier to search in Workspace ONE.

1. Log in to the Workspace ONE administration panel, navigate to Devices → List View, and select a device to view.
2. Under "List view", locate the "Device Info".
3. The "UDID" is the device identifier. Copy this value and use it to perform the search in Duo.

Removing the Workspace ONE Management Integration

Deleting a trusted endpoints management tool integration from the Duo Admin Panel immediately invalidates issued Duo device authentication certificates. Be sure to unassign your trusted endpoints policy from all applications or remove the "Trusted Endpoints" configuration item from your global policy before deleting an existing Workspace ONE integration from "Trusted Endpoints Configuration". You should also disable your Duo admin user in Workspace ONE.

Leaving the policy settings in place after deleting a management tools integration may inadvertently block user access to applications.
