Still Using Passwords? Get Started with Phishing-Resistant, Passwordless Authentication Now!

By Jackie Castelli

Going beyond the hype, passwordless authentication is now a reality. Cisco Duo’s passwordless authentication is now generally available across all Duo Editions.

“Cisco Duo simplifies the passwordless journey for organizations that want to implement phishing-resistant authentication and adopt a zero trust security strategy.”
—Jack Poller, Senior Analyst, ESG

We received tremendous participation and feedback during our public preview, and we are now excited to bring this capability to our customers and prospects.

“Over the last few years, we have increased our password complexities and required 2FA wherever possible.  With this approach, employees had more password lock outs, password fatigue, and forgetting their longer passwords due to password rotations.  With Duo Passwordless, we are excited to introduce this feature to our employees to keep our password complexities in place and leverage different Biometric options whether that is using their mobile device, Windows Hello, or a provided FIDO security key. 

The Duo Push for passwordless authentication feature is simple and easy and introduces a more pleasant experience overall.  Using Duo’s device insight and application policies, we are able to leverage and verify the security of the mobile devices before the device is allowed to be used.  To top it off, Duo is connected to our SIEM and our InfoSec team is able to review detailed logs and setup alerts to be able to keep everything secure.”
—Vice President of IT, Banking and Financial Services Customer

As with any new technology, getting to a completely passwordless state will be a journey for many organizations. We see customers typically starting their passwordless journey with web-based applications that support modern authentication. To that effect, Duo’s passwordless authentication is enabled through Duo Single Sign-On (SSO) for federated applications. Customers can choose to integrate their existing SAML Identity provider such as Microsoft (ADFS, Azure), Okta or Ping Identity; or choose to use Duo SSO (Available across all Duo editions).

“Password management is a challenging proposition for many enterprises, especially in light of BYOD and ever increasing sophistication of phishing schemes. Cisco aims to simplify the process with its Duo passwordless authentication that offers out-of-box integrations with popular single sign-on solutions.”
—Will Townsend, Vice President & Principal Analyst, Networking & Security, Moor Insights & Strategy

Duo’s Passwordless Architecture

Duo Passwordless Architecture

Duo offers a flexible choice of passwordless authentication options to meet the needs of businesses and their use cases. This includes:

  1. FIDO2-compliant, phishing-resistant authentication using
    • Platform authenticators – TouchID, FaceID, Windows Hello, Android biometrics
    • Roaming authenticators – security keys (e.g. Yubico, Feitian)
  2. Strong authentication using Duo Mobile authenticator application

No matter which authentication option you choose, it is secure and inherently multi-factor authentication. We are eliminating the need for the weak knowledge factor (something you know – passwords) which are shared during authentication and can be easily compromised. Instead, we are relying on stronger factors, which are the inherence factor (something you are – biometrics) and possession factor (something you have – a registered device). A user completes this authentication in a single gesture without having to remember a complex string of characters. This significantly improves the user experience and mitigates the risk of stolen credentials and man-in-the-middle (MiTM) attacks.

Phishing resistant passwordless authentication with FIDO2

Passwordless authentication using FIDO2

FIDO2 authentication is regarded as phishing-resistant authentication because it:

  1. Removes passwords or shared secrets from the login workflow. Attackers cannot intercept passwords or use stolen credentials available on the dark web.
  2. Creates a strong binding between the browser session and the device being used. Login is allowed only from the device authenticating to an application.
  3. Ensures that the credential (public/private key) exchange can only happen between the device and the registered service provider. This prevents login to fake or phishing websites.

Using Duo with FIDO2 authenticators enables organizations to enforce phishing-resistant MFA in their environment. It also complies with the Office of Management and Budget (OMB) guidance issued earlier this year in a memo titled “Moving the U.S. Government Towards Zero Trust Cybersecurity Principles”. The memo specifically requires agencies to use phishing-resistant authentication method.

We understand that getting the IT infrastructure ready to support FIDO2 can be expensive and is typically a long-term project for organizations. In addition, deploying and managing 3rd party security keys creates IT overhead that some organizations are not able to undertake immediately.

Alternatively, using Duo Push for passwordless authentication is an easy, cost effective to get started on a passwordless journey for many organizations, without compromising on security.

Strong passwordless authentication using Duo Mobile

We have incorporated security into the login workflow to bind the browser session and the device being used. So, organizations get the same benefits of eliminating use of stolen credentials and mitigation of phishing attacks.

Beyond passwordless: Thinking about Zero Trust Access and continuous verification

passwordless authentication

In addition to going passwordless, many organizations are looking to implement zero trust access in their IT environment. This environment typically is a mix of modern and legacy applications, meaning passwordless cannot be universally adopted. At least not until all applications can support modern authentication.

Additionally, organizations need to support a broad range of use cases to allow access from both managed and unmanaged (personal or 3rd party contractor) devices. And IT security teams need visibility into these devices and the ability to enforce compliance to meet the organization’s security policies such as ensuring that the operating system (OS) and web browser versions are up to date. The importance of verifying device posture at the time of authentication is emphasized in the guidance provided by OMB’s zero trust memorandum – “authorization systems should work to incorporate at least one device-level signal alongside identity information about the authenticated user.”

Duo can help organizations adopt a zero trust security model by enforcing strong user authentication across the board either through passwordless authentication where applicable or thought password + MFA where necessary, while providing a consistent user experience. Further, with capabilities such as device trust and granular adaptive policies, and with our vision for Continuous Trusted Access, organizations get a trusted security partner they can rely on for implementing zero trust access in their environment.

How Cisco Duo Is Simplifying Secure Access for Organizations Around the World

By Jackie Castelli

At Cisco Duo, we continually strive to enhance our products to make it easy for security practitioners to apply access policies based on the principles of zero trust. This blog highlights how Duo is achieving that goal by simplifying user and administrator experience and supporting data sovereignty requirements for customers around the world. Read on to get an overview of what we have been delivering to our customers in those areas in the past few months.

Simplifying Administrator and End-User Experience for Secure Access 

Duo strives to make secure access frictionless for employees while reducing the administrative burden on IT (Information Technology) and helpdesk teams. This is made possible thanks to the strong relationship between our customers and our user research team. The insights we gained helped us implement some exciting enhancements to Duo Single Sign-On (SSO) and Device Trust capabilities.

Duo SSO unifies identities across systems and reduces the number of credentials a user must remember and enter to gain access to resources. Active Directory (AD) is the most popular authentication source connected to Duo SSO, accounting for almost 80% of all setups. To make Duo’s integration with AD even easier to implement, we have introduced Duo SSO support for multiple Active Directory forests for organizations that have users in multiple domains. Additionally, we added the Expired Password Resets feature in Duo SSO. It provides an easy experience for users to quickly reset their expired Active Directory password, log into their application, and carry on with their day. Continuing the theme of self service, we introduced a hosted device management portal – a highly requested feature from customers. Now administrators no longer need to host and manage the portal, and end users can login with Duo SSO to manage their authentication devices (e.g.: TouchID, security keys, mobile phone etc.) without needing to open IT helpdesk tickets.

We are also simplifying the administrator experience. We have made it easy for administrators to configure Duo SSO with Microsoft 365 using an out of the box integration. Duo SSO layers Duo’s strong authentication and flexible policy engine on top of Microsoft 365 logins. Further, we have heard from many customers that they want to deliver a seamless on-brand login experience for their workforce. To support this, we have made custom branding so simple that administrators can quickly customize their end-user authentication experience from the settings page in the Duo Admin Panel.

Device Trust is a critical capability required to enable secure access for the modern workforce from any location. We have made it easy for organizations to adopt device trust and distinguish between managed and unmanaged devices. Organizations can enforce a Trusted Endpoint policy to allow access only from managed devices for critical applications. We have eliminated the requirement to deploy and manage device certificates to enforce this policy. Device Health application now checks the managed status of a device. This lowers administrative overhead while enabling organizations to achieve a better balance between security and usability. We have also added out-of-box integrations with unified endpoint management solutions such as Active Directory domain-joined devices, Microsoft Intune, Jamf Pro and VMware Workspace ONE. For organizations that have deployed a solution that is not listed above, Duo provides a Device API that works with any enterprise device management system.

 Supporting Global Data Sovereignty Requirements 

To support our growing customer base around the world, Duo expanded its data center presence to  Australia, Singapore, and Japan in September last year. And now Duo is thrilled to announce the launch of the two new data centers in the UK and India. Both the new and existing data centers will allow customers to meet all local requirements, all while maintaining ISO27001 and SOC2 compliance and a 99.999% service availability goal.

The launch of the new data centers is the backbone of Duo’s international expansion strategy. In the last two years, Duo has met key international growth milestones and completed the C5 attestation (Germany), AgID certification (Italy) and IRAP assessment (Australia) – all of which demonstrate that Duo meets the mandatory baseline standards for use by the public sector in the countries listed above.
