Detect Malware Threats Using AWS Transfer Family Diagram

Reference architecture diagram showing how to securely share files over SFTP, FTP, and FTPS within many business-to-business (B2B) workflows across various industries including retail, advertising, and regulated environments like healthcare and financial services.

  1. Send an authentication request to the AWS Transfer Family server, which forwards the request to authenticate you using a custom identity provider.

  2. Upload the files to the Transfer Family server. Each file put into an Amazon Simple Storage Service (Amazon S3) bucket and invokes a distinct workflow execution.

  3. The Transfer Family managed workflow initializes a sequence of pre-processing steps on the uploaded file before being consumed by the downstream applications. In the workflow step, the AWS Lambda function scans each file with a Clam AntiVirus (ClamAV) installed container image.

  4. Based on the scan result from the Lambda function, the managed workflow tags the files appropriately either as INFECTED or CLEAN.

  5. An Amazon EventBridge Scheduler rule is configured to run based on a cron expression to update the ClamAV image and virus definitions.

  6. AWS CodeBuild builds the container image adds the latest Clam AV virus definitions and uploads to Amazon Elastic Container Registry (Amazon ECR).

  7. The Lambda function pulls the built container image from Amazon ECR and updates the Lambda function as part of the managed workflow.
