Duo Single Sign-On for Cisco Umbrella

Last Updated: March 30th, 2020

Duo offers a variety of methods for adding two-factor authentication and flexible security policies to Cisco Umbrella SSO logins, complete with inline self-service enrollment and Duo Prompt.

Overview

As business applications move from on-premises to cloud hosted solutions, users experience password fatigue due to disparate logons for different applications. Single sign-on (SSO) technologies seek to unify identities across systems and reduce the number of different credentials a user has to remember or input to gain access to resources.

While SSO is convenient for users, it presents new security challenges. If a user's primary password is compromised, attackers may be able to gain access to multiple resources. In addition, as sensitive information makes its way to cloud-hosted services it is even more important to secure access by implementing two-factor authentication.

Duo Single Sign-On

Duo Single Sign-On, now in public beta, is our cloud-hosted SSO product which layers Duo's strong authentication and flexible policy engine on top of Cisco Umbrella logins using the Security Assertion Markup Language (SAML) 2.0 authentication standard. Duo Single Sign-On acts as an identity provider (IdP), authenticating your users using existing on-premises Active Directory (AD) or any SAML 2.0 IdP and prompting for two-factor authentication before permitting access to Cisco Umbrella.

Duo Single Sign-On's public beta is available in Duo Beyond, Duo Access, and Duo MFA plans, which also include the ability to define policies that enforce unique controls for each individual SSO application. For example, you can require that Salesforce users complete two-factor authentication at every login, but only once every seven days when accessing Cisco Umbrella. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Configure Single Sign-On

Before configuring Cisco Umbrella you'll first need to configure Duo Single Sign-On with a working an authentication source.

Create the Cisco Umbrella Application in Duo

  1. Log on to the Duo Admin Panel and navigate to Applications.

  2. Click Protect an Application and locate the "Single Sign-On (hosted by Duo)" entry for Cisco Umbrella in the applications list. Click Protect to the far-right to start configuring Cisco Umbrella. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Cisco Umbrella page under Downloads later.

  3. Cisco Umbrella uses the Mail attribute when authenticating. We've mapped the <Email Address> bridge attribute to Duo Single Sign-On supported authentication source attributes as follows:

    Bridge Attribute Active Directory SAML IdP
    <Email Address> mail Email

    If you are using a non-standard email attribute for your authentication source, check the Custom attributes box and enter the name of the attribute you wish to use instead.

  4. You can adjust additional settings for your new SAML application at this time — like changing the application's name from the default value, enabling self-service, or assigning a group policy.

  5. Scroll to the bottom of the page and click the Save button.

Configure Cisco Umbrella SSO

Configure Duo Single Sign-On as a new SSO provider in Cisco Umbrella.

  1. Log on to Cisco Umbrella as an administrative user and navigate to AdminAuthentication and under "SAML Dashboard User Configuration" click on Enable SAML.

  2. When asked "Which SAML based SSO Service would you like to use?" click Other and then click Next.

  3. On the Umbrella Metadata page click Next.

  4. Click Download XML next to "XML file" under Downloads on your Cisco Umbrella application's details page in the Duo Admin Panel to download the Duo Single Sign-On XML metadata file. On the Cisco Umbrella Upload and Verify Other Metadata page under "XML File Upload" click Or select a file... and select the XML metadata file.

  5. Click Test Configuration. A pop-up will appear and redirect to the Duo Single Sign-On login page. Enter your primary directory logon information and approve Duo two-factor authentication. You will see a "Success" message. Close this window, return to the configuration page, and click Next

  6. You will be asked to accept terms and conditions and click Save and Notify Users. This will enable SSO and send an email to your employees notifying them of the change.

Log in with SSO

Navigate to the Cisco Umbrella login page and click the Single sign on link. Enter your email address and click Sign In. This redirects to the Duo Single Sign-On login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the Cisco Umbrella site after authenticating.

Duo Single Sign-On Login and Authentication Prompt

Congratulations! Your Cisco Umbrella users now authenticate using Duo Single Sign-On.

Enable Remembered Devices

To minimize additional Duo two-factor prompts when switching between Cisco Umbrella and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.

Microsoft AD FS

Microsoft's Active Directory Federation Services (AD FS) is a popular choice for SSO because it easily integrates with the AD identity store many organizations already have deployed. Duo's support for cloud applications and SSO drops in to an existing AD FS installation to provide secondary authentication after a user passes primary authentication (successful Active Directory logon).

If you don't already have AD federation running the first step is to install and configure Microsoft AD FS in your organization. Deployment Guides for AD FS versions 2.1, and 3.0/4.0 are available from Microsoft.

Once your AD FS services are up and running, the second step is to configure the SSO partnership between your AD FS service and the external cloud resource, in this case Cisco Umbrella. Learn more about configuring Cisco Umbrella SSO with AD FS at the Cisco Umbrella Support site.

After you have successfully configured and tested AD FS SSO login to Cisco Umbrella using your AD domain credentials, you can then install the Duo AD FS integration. AD FS protection is included with Duo's paid plans.

With the Duo integration for AD FS installed, users pass primary authentication to the AD FS service as usual. Once primary authentication succeeds, users are forwarded to the Duo service for secondary authentication. After approving logon using one of Duo's authentication methods, the user is fully logged in to Cisco Umbrella.

Other Identity Partners

Using a third-party SSO provider for cloud application access? Duo partners with leading cloud SSO providers like Okta and OneLogin to secure access with our strong and flexible authentication platform.

You can also use Duo two-factor authentication with CAS and Shibboleth on-premises IdPs.
