Mar 1, 2025Monthly summary for 2025-03: Delivered reliability enhancements to AWS Network Firewall Suricata rule loading in the terraform-aws-vpc-nfw module. Implemented prioritization of a provided rules_file, made the rules_file input optional, and added a robust fallback to a local default when the file is missing or not found. Fixed a minor path typo to ensure correct referencing of the rules file, improving testability and operational reliability. These changes reduce rule-loading failures and simplify validation in CI. Impact: improved firewall policy reliability in customer deployments and smoother testing. Technologies/skills demonstrated: Terraform module development, AWS Network Firewall and Suricata integration, robust input handling, and testing.
