Cloud Security Platform

Secure-by-default cloud security platform demonstrating Terraform guardrails, cloud detection and response, Kubernetes policy enforcement, and CI/CD supply chain security.

Highlights

• Terraform-based secure infrastructure patterns
• AWS detection and response workflows
• Kubernetes policy enforcement with Kyverno/OPA
• CI/CD security with scanning, SBOM, and signing
• Developer-friendly secure-by-default control

How It Works

1. Infrastructure is provisioned through Terraform modules with embedded security guardrails
2. CI/CD pipelines validate code, IaC, dependencies, and container images
3. Kubernetes admission policies enforce runtime security controls
4. AWS detection and response workflows monitor activity and trigger automated response actions
5. Logs, metrics, and alerts improve incident visibility and readiness

Objectives

• Build secure-by-default infrastructure
• Automate detection and response
• Enforce preventive security controls
• Improve developer velocity with built-in guardrails

Core Components

• AWS foundational security controls
• Terraform modules
• GuardDuty, Security Hub, and CloudTrail
• EventBridge + Lambda remediation
• Kyverno / OPA policy enforcement
• GitHub Actions supply chain security pipeline

Design Decisions

• Terraform was used to standardize secure infrastructure patterns and reduce configuration drift
• AWS-native detection services were used to demonstrate practical cloud monitoring and response workflows
• Kubernetes policy enforcement was added to shift runtime controls left into platform defaults
• CI/CD supply chain controls were included to reduce the risk of vulnerable or unsigned artifacts reaching deployment

Repository Structure

• infrastructure/terraform/ reusable infrastructure definitions
• detection-response/ monitoring, alerting, and automated response workflows
• platform-security/ secure-by-default platform controls

Outcomes

This project demonstrates:

• reduced cloud misconfiguration risk through secure defaults
• improved incident readiness through automated detection and response
• repeatable infrastructure deployment through Terraform
• security enablement that helps developers ship safely and quickly

Why This Project Matters

This project demonstrates how cloud security can be engineered as part of the platform itself through automation, preventative controls, detection and response, and developer enablement rather than ticket-driven security work.
