Matthew Fennemore enhanced AWS infrastructure automation by developing granular access controls and policy management features across Terraform modules. On the schubergphilis/terraform-aws-mcaf-securityhub-findings-manager repository, he consolidated and refactored IAM policies for the Findings Manager Lambda, enabling precise S3 GetObject and ListBucket permissions while improving policy readability and maintainability. In the schubergphilis/terraform-aws-mcaf-s3 repository, Matthew introduced support for Access Control Policies on S3 buckets, allowing fine-grained grants via an optional variable integrated into the bucket ACL. Throughout both projects, he applied Infrastructure as Code best practices using HCL and Terraform, ensuring secure, maintainable, and auditable cloud resource configurations.

May 2025: Security and maintainability improvements for the Terraform-based AWS MCAP S3 module. Delivered granular Access Control Policies (ACP) support for S3 buckets managed by Terraform with an optional ACP variable integrated into the bucket ACL, enabling precise grants to owners and other grantees. Performed a formatting cleanup across Terraform configurations to align with style guidelines, improving readability and maintainability. These changes reduce risk, speed up future enhancements, and lay groundwork for policy-driven access controls.

Month 2025-03: Consolidated IAM policy improvements for the Findings Manager Lambda within the Terraform module to enable S3 GetObject and ListBucket access with granular, clearly separated statements and corrected policy formatting. This work enhances security, reliability, and maintainability of the findings workflow, aligning with least-privilege principles and reducing risk in production deployments.
