Automated DevOps Pipeline with System Hardening and CI/CD

This project delivers a fully automated DevOps pipeline focused on system hardening and secure, reliable application deployment. It enhances cloud-based application security, ensures consistency across environments, and streamlines CI/CD workflows for production-grade deployment.

Project Overview

Cloud-based Development & Management:
Development and testing leveraged AWS Cloud9, while AWS Glue facilitated data integration and transformation tasks.

System Hardening & Security:
Linux servers (CentOS, RHEL) were hardened using automated scripts to enforce security best practices. Windows systems were secured alongside, and Kali Linux tools were leveraged for vulnerability assessment.

CI/CD Pipeline Automation:
Monolithic applications were analyzed and migrated using the Migration Toolkit for Applications (MTA). Deployment pipelines were automated via OpenShift Tekton, enabling repeatable, fast, and reliable application updates.

Infrastructure as Code:
Cloud resources and pipelines were provisioned using Terraform, ensuring version-controlled, auditable infrastructure changes.

Key Features & Workflow:

1

Automated OS Hardening:

– Enforced security policies on Linux servers using Ansible.
– Reduced attack surface and improved compliance posture.

2

CI/CD for Monolithic Apps:

– Tekton pipelines on OpenShift automate build, test, and deployment processes.
– Migration Toolkit for Applications (MTA) analyzed and migrated legacy applications to cloud environments.

3

Infrastructure as Code (IaC):

– Terraform scripts provisioned and managed cloud resources consistently.
– Ensured version-controlled and auditable infrastructure changes.

4

Cloud-based Development & Integration:

– AWS Cloud9 provided a collaborative IDE for development and testing.
– AWS Glue handled ETL workflows and data integration tasks.

5

Security Monitoring & Assessment:

– Continuous monitoring for vulnerabilities and compliance.
– Integrated Kali Linux tools for penetratTerraform scripts provisioned and managed cloud resources consistently.
– Ensured version-controlled and auditable infrastructure changes.ion testing and risk assessment.

Summary

Developed a secure, automated DevOps pipeline combining system hardening, CI/CD, and cloud infrastructure provisioning. Leveraged Ansible, Terraform, OpenShift Tekton, and cloud tools to ensure secure, repeatable, and highly reliable deployment of applications across environments.
