Kourosh Mobl engineered robust network security and observability features in the Coalfire-CF/terraform-aws-vpc-nfw repository, focusing on AWS infrastructure using Terraform and Go. Over four months, he delivered enhancements such as unified VPC endpoint security groups, secure S3 destinations for VPC Flow Logs, and advanced AWS Network Firewall stateful rule processing. His work consolidated access controls, improved auditability, and reduced configuration drift by centralizing security group management and enforcing encryption and access policies. Kourosh maintained clear version control and documentation, implemented automated testing with Terratest and GitHub Actions, and addressed both feature development and codebase maintainability with disciplined infrastructure-as-code practices.

June 2025 monthly delivery focused on secure observability for VPC networks in the terraform-aws-vpc-nfw module. Delivered a secure S3 destination for VPC Flow Logs with encryption, strict access controls, and end-to-end logging. Updated naming conventions and Terraform resources to target S3 as the destination. This work strengthens security posture, enhances monitoring, and enables centralized, auditable logs for faster incident response and compliance.

February 2025: Delivered AWS Network Firewall Stateful Rule Processing Enhancements in the terraform-aws-vpc-nfw module. Introduced new variables and configurations to control stateful rule processing, including default actions for stateful traffic and options to configure the stateful engine. This enables default drop actions and finer-grained engine tuning, improving security posture and automation across deployments. The change is implemented with a clear git history and is documented for ease of adoption. Commit 8878958de00d274da2ae74850674df11ec7ab9f2.
