Miguel Pais developed the initial VM Workload Scanning feature for the sysdiglabs/terraform-aws-secure repository, enabling agentless scanning of AWS workloads. He designed the module to support both single-account and organizational deployments using CloudFormation StackSets, which allows scalable onboarding across multiple AWS environments. His work involved creating IAM roles and policies for secure ECR image pulling and optional Lambda function scanning, leveraging Terraform and HCL for infrastructure as code. Miguel also addressed a cloud authentication integration issue by ensuring role identifiers were stored as role names rather than ARNs, resolving authorization problems and improving compatibility with cloud authentication services.
