Cisco Duo MFA on AWS

Duo MFA with AWS Fargate serverless compute engine

View deployment guide

This Partner Solution deploys Duo MFA to the Amazon Web Services (AWS) Cloud. It's for those who want to use AWS Directory Service directory types and apply Duo MFA. Directory Service directory types include AWS Directory Service for Microsoft Active Directory (AWS Managed Microsoft AD) and Active Directory Connector (AD Connector).

With this Partner Solution, you deploy Duo using the AWS Fargate serverless compute engine for containers. You can build an environment that's ready for compliance with Cybersecurity Maturity Model Certification (CMMC). Since CMMC certification is typically required of U.S. Department of Defense contractors, this Partner Solution supports Duo Federal Edition.

Deploying this solution does not guarantee an organization’s compliance with any laws, certifications, policies, or other regulations.

  •  What you'll build

  • This Partner Solution sets up the following:

    • A highly available architecture that spans two Availability Zones.*
    • A virtual private cloud (VPC) configured with public and private subnets, according to AWS best practices, to provide you with your own virtual network on AWS.*
      • In the public subnets, managed network address translation (NAT) gateways to allow outbound internet access for resources in the private subnets.*
      • A serverless managed AWS Fargate cluster with containers for Duo Authentication Proxy. The cluster is replaced whenever a new image is deployed or whenever the secrets are updated.
    • A continuous integration and continuous delivery (CI/CD) pipeline for image deployment:
      • AWS CodePipeline to retrieve the latest code from AWS CodeCommit in response to an Amazon CloudWatch event once a week by default.
      • AWS CodeBuild, which CodePipeline uses to build a new container image. CodePipeline then uploads the new container image to Amazon Elastic Container Registry (Amazon ECR).
    • Image discovery:
      • Amazon ECR, which stores each new container image.
      • Amazon Elastic Container Service (Amazon ECS), which discovers the images and pushes them to Fargate.
    • CloudWatch CPU and memory alarms that invoke Amazon Simple Notification Service (Amazon SNS) notifications to Duo administrators.
    • An AWS Key Management Service (AWS KMS) key that encrypts all Duo Authentication Proxy–related resources.
    • Secrets and events management, which works as follows (a two- to three-minute process):
      • AWS Secrets Manager rotates the secrets that are used for the cluster.
      • With each rotation, an AWS Lambda function replaces the Fargate containers, deploying the newest image.
      • After the Fargate containers stabilize, a CloudWatch event initiates a second Lambda function to update the Duo MFA settings in AWS Systems Manager Parameter Store.
      • Finally, a CloudWatch event initiates a third Lambda function. This function either updates AWS Directory Service or, if the update fails, sends Duo administrators an SNS notification.

    * The template that deploys the Partner Solution into an existing VPC skips the components marked by asterisks and prompts you for your existing VPC configuration.

  •  How to deploy

  • To deploy Duo MFA on AWS, follow the instructions in the deployment guide. The deployment process takes about 45 minutes and includes these steps:

    1. Sign up for a license at https://duo.com/editions-and-pricing.
    2. Sign in to your AWS account. If you don't have an account, sign up at https://aws.amazon.com.
    3. Launch the Partner Solution. Before you create the stack, choose the AWS Region from the top toolbar. You can choose from two options:
    4. Verify your deployment.
    5. (Optional) Modify your implementation.

    Amazon may share user-deployment information with the AWS Partner that collaborated with AWS on this solution.

  •  Costs and licenses

  • This Partner Solution requires a license for Duo MFA. You must set up at least one Duo user whose email address is associated with at least one user in Microsoft Active Directory. For more information, refer to Duo Editions & Pricing.

    You are responsible for the cost of the AWS services and any third-party licenses used while running this solution. There is no additional cost for using the solution.

    This solution includes configuration parameters that you can customize. Some of these settings, such as instance type, affect the cost of deployment. For cost estimates, refer to the pricing pages for each AWS service you use. Prices are subject to change.

    Tip: After you deploy a solution, create AWS Cost and Usage Reports to track associated costs. These reports deliver billing metrics to an Amazon Simple Storage Service (Amazon S3) bucket in your account. They provide cost estimates based on usage throughout each month and aggregate the data at the end of the month. For more information, refer to What are AWS Cost and Usage Reports?
