AWS EKS Secure Deployment Architecture 🚀

This project demonstrates a secure, scalable Kubernetes deployment on Amazon EKS (Elastic Kubernetes Service), implementing enterprise-grade cloud security, network segmentation, and DevSecOps best practices.

Business Goal

  • Deploy containerized microservices on AWS EKS with Zero Trust architecture
  • Enable continuous compliance (PCI-DSS, SOC2, ISO 27001)
  • Integrate DevSecOps pipeline with automated security checks
  • Achieve strong auditing, visibility, and runtime monitoring

Architecture Overview

  • Amazon VPC with isolated private subnets, NACLs, and security groups
  • AWS EKS — hardened control plane and managed Kubernetes
  • IAM Roles for Service Accounts (IRSA)
  • AWS WAF & ALB for Layer 7 ingress protection
  • Continuous threat detection with AWS GuardDuty & Inspector
  • Secrets encryption with AWS KMS
  • OPA Gatekeeper for policy-as-code enforcement
  • Calico / Cilium — Kubernetes network segmentation (NetworkPolicies)
  • Observability stack — Prometheus, Grafana, ELK

Tools & Technologies

  • AWS EKS, VPC, IAM, GuardDuty, Inspector, KMS, WAF, ALB
  • OPA Gatekeeper, Istio, Calico/Cilium
  • Jenkins, Terraform, SonarQube, Checkmarx, Burp Suite Pro
  • Trivy, GitLeaks, Falco
  • Prometheus, Grafana, ELK Stack

Security Controls Implemented

  • Zero Trust service-to-service communication (mTLS with Istio)
  • RBAC and IAM-based access control (IRSA)
  • PodSecurityPolicies & OPA constraints
  • Audit logging — AWS CloudTrail, EKS audit logs
  • Runtime security with Falco
  • Continuous scanning — SAST, DAST, container image scans

Implementation Details

Full EKS cluster and networking were built with Terraform modules. Jenkins pipelines were extended with security stages (SAST, DAST, image scan, secrets scan). IAM roles and Kubernetes RBAC were designed to follow least-privilege. OPA policies and PodSecurityPolicies enforced baseline hardening. Observability stack provided dashboards and alerts.

Business Impact

  • Reduced vulnerability window by 60%
  • Automated compliance reporting for SOC2, ISO 27001
  • Improved MTTR (Mean Time To Resolution) by 45%
  • Full DevSecOps adoption — code-to-deploy security built-in
