![]() ![]() ![]() If you are already running a Duo Authentication Proxy server in your environment, you can use that existing host for additional applications, appending the new configuration sections to the current config. This Duo proxy server will receive incoming RADIUS requests from your Cisco ASA SSL VPN, contact your existing local LDAP/AD or RADIUS server to perform primary authentication if necessary, and then contact Duo's cloud service for secondary authentication. To integrate Duo with your Cisco ASA SSL VPN, you will need to install a local Duo proxy service on a machine within your network. You should already have a working primary authentication configuration for your Cisco ASA SSL VPN users before you begin to deploy Duo. You'll need to pre-enroll your users in Duo using one of our available methods before they can log in using this configuration. Log on to your Cisco ASDM interface and verify that your Cisco ASA firmware is version 8.3 or later.īefore moving on to the deployment steps, it's a good idea to familiarize yourself with Duo administration concepts and features like options for applications, and Duo policy settings and how to apply them. If you need to protect connections that use Cisco's desktop VPN client (IKE encryption), use our Cisco IPSec instructions.īefore starting, make sure that Duo is compatible with your Cisco ASA device. ![]() Please refer to the Duo for Cisco An圜onnect VPN with ASA or Firepower overview to learn more about the different options for protecting ASA logins with Duo MFA. ![]() Primary and Duo secondary authentication occur at the identity provider, not at the ASA itself. This deployment option features Duo Single Sign-On, our cloud-hosted SAML 2.0 identity provider. The SAML VPN instructions feature inline enrollment and the interactive Duo Prompt for both web-based VPN logins and An圜onnect 4.6+ client logins. If you need inline self-service enrollment and the Duo Prompt for web-based VPN logins, refer to the ASA LDAPS SSL VPN Instructions. This configuration does not feature the interactive Duo Prompt for web-based logins, but does capture client IP informations for use with Duo policies, such as geolocation and authorized networks. The Cisco An圜onnect RADIUS instructions support push, phone call, or passcode authentication for An圜onnect desktop and mobile client connections that use SSL encryption. If you have any questions or need assistance, please contact the TTS Service Desk at 61 or - Security measure for a website, application, or online service that checks if you're allowed to access it based on some specific information/criteria which protects our online spaces by making sure only authorized individuals or groups can gain access.Duo integrates with your Cisco ASA VPN to add two-factor authentication to any VPN login. Supportįor specific directions, please refer to the DUOSecurity Online User Guide. Verified DUO Push uses the “remember me” feature, so you won't get the message for the next 30 days and then it will ask for a code again.ĭUO Phone Call: The process to verify a DUO phone call will require you to press 1 to approve and 9 to decline a login reducing any accidental keypad entries that could provide access to an attacker looking to steal your data. All other applications (i.e., Tufts VPN, Windows servers, etc.) will use simple DUO Push NOT the “Verified DUO Push”. Verified DUO Push will be required for all web applications (i.e., Box, Zoom, etc.) that are Shibboleth-enabled *. Verifying your DUO Authentication requires a simple but more conscious action before approving the login via Push or Phone call.ĭUO Push: “Verified DUO Push” requires a user to input a verification code on the Duo Mobile app when approving a login request, rather than simply tapping Approve or Deny. Attackers take advantage of human weakness by what is known as “push harassment” or “push fatigue” hoping that you pay less attention to the details or whether you initiated the action. How verification worksĬurrently, our DUO implementation makes it easy to accidentally accept a DUO push notification or press on any key to accept a phone notification. Verifying your DUO authentication increases our security and will help protect you and secure your data from unauthorized access that you didn’t initiate. Effective November 1, 2023, Tufts will implement a verification step for DUO for both push and phone notifications. ![]()
