🛡️ DevSecOps Pipeline - Kubernetes DevOps & Security

A complete DevSecOps pipeline implementing security best practices, automation, and deployment on Kubernetes with AWS EKS.

🎯 Overview

This project demonstrates the implementation of a robust and secure DevSecOps pipeline, integrating multiple security tools, test automation, and Kubernetes deployment. The pipeline ensures that every commit goes through rigorous security checks before being deployed to production.
