Deploying Zero-Trust Cyber Security Pipelines in AWS with DevOps & Docker

## Zero-Trust Cloud Architecture

In a modern Zero-Trust environment, **never trust, always verify**. Every request originating inside or outside your perimeter must be authenticated, authorized, and encrypted.

Container Security Best Practices 1. **Non-Root Docker Containers**: Always configure your `Dockerfile` to run applications under unprivileged system user IDs. 2. **Minimal Base Images**: Use Distroless or Alpine Linux base images to eliminate unnecessary shell utilities and binaries. 3. **Secrets Management**: Inject API keys dynamic at runtime using AWS Secrets Manager or HashiCorp Vault.
