Duo Trusted Endpoints - Cisco Meraki Systems Manager 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 allow REST API access for Duo to your managed mobile devices, or deploy Duo Desktop to Windows and macOS managed systems.

This guide walks you through Cisco Meraki Systems Manager configuration for Windows and macOS endpoint clients and Android and iOS mobile devices.

Prerequisites

• Access to the Duo Admin Panel as an administrator with the Owner, Administrator, or Application Manager administrative roles.
• Access to the Cisco Meraki Systems Manager Dashboard as an administrator with the rights to create managed apps, app profiles, API keys, and device profiles.

If you plan to verify trust status for Windows and macOS systems:

• Add your Windows and macOS devices to the Meraki device list and enroll your devices in Meraki Systems Manager.

• Deploy Duo Desktop for Windows 10 and later or macOS to your Meraki-managed endpoints. Refer to the Duo Desktop documentation to learn about different options for deploying the application.

  Note that you do not need to configure a Duo Desktop policy in order to use Meraki with Duo Desktop.

Android Configuration

Duo determines trusted device status on Android devices by leveraging the installed and activated Duo Mobile application on a given device to verify device information. To enable this verification you'll need to grant Duo read-only access to those devices via your Meraki's API access.

End of Life Information

New Meraki certificate deployment management integrations may no longer be created as of October 2021, and reached end of life on October 7. 2024. Duo device certificates will no longer renew after October 2024. You must migrate your certificate-based iOS Cisco Meraki integration to Cisco Meraki with App Config. See the Duo Knowledge Base article Guide to updating Trusted Endpoints iOS integrations from certificates to AppConfig for more information about migrating your iOS certificate-based management integrations to App Config.

Use of the Duo Desktop for trust attestation provides several advantages over the use of device certificates:

• It provides a more accurate assessment of your managed devices, and removes concerns about long-lived certificates present on devices no longer managed by your organization.
• It extends support to Firefox users. Trusted Endpoint certificate detection only works with Chrome, Edge, Safari, and Internet Explorer (depending on the management system).
• Improves trust detection for web browsers and thick client applications.

See the Duo Trusted Endpoints Certificate Migration Guide for more information.

Finish Trusted Endpoints Deployment

Once your Meraki 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 Meraki 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 Cisco Meraki management 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

Users see a device trust dialog on their iOS and Android devices when authenticating to a protected resource via the Duo Prompt.

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

If Duo successfully verifies the device information using the Meraki 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.

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 Cisco Meraki Systems Manager, 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 Meraki 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 Cisco Meraki Systems Manager, Meraki with Duo Desktop, or Cisco Meraki 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 Meraki API configuration and wait 24 hours.

Use these instructions to find the device identifier for iOS and Android devices to search in Meraki:

1. Log in to the Meraki Systems Manager, navigate to Device list and select a device to view.

2. In the URL for the device view, there will be a URL parameter called "pn".

   Example: /manage/pcc/list#pn=123456789123456789

3. The "pn" is the device identifier. Copy this value and use it to perform the search in Duo.

Use these instructions to find the device identifier for Windows and macOS devices to search in Meraki:

1. Log in to the Meraki Systems Manager and navigate to Device list.
2. Click the gear icon in the top-right corner of the device list table to make the UUID column visible.
3. The "UUID" is the device identifier. Copy this value and use it to perform the search in Duo.

Removing the Meraki Management Integration

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 Meraki integration from "Trusted Endpoints Configuration".

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

Deleting a trusted endpoints management tool integration from the Duo Admin Panel immediately invalidates issued Duo device authentication certificates.
