Project Portfolio

AWS-EKS-Cluster-Terraform

Provisioned a secure and scalable AWS infrastructure using Terraform by creating a VPC with 2 public and 2 private subnets across multiple availability zones. Deployed an Amazon EKS cluster with its node group in private subnets to enhance security. Configured NAT Gateways in public subnets for controlled internet access. This setup provides a robust foundation for running containerized workloads in a production-ready Kubernetes environment.

Capture The Flag (CTF) Challenge

Designed a Capture The Flag (CTF) challenge focused on Remote Code Execution (RCE) vulnerabilities in a containerized environment. Utilized Docker for containerization and Nginx as a reverse proxy to simulate real-world scenarios. Participants engage in hands-on exercises to identify, exploit, and mitigate RCE vulnerabilities, gaining practical cybersecurity experience while exploring the security aspects of Docker and reverse proxies.
