Title: Zero-Trust Identity & Pipeline Access Hardening (Lab 2)

Overview

A hands-on implementation of Zero-Trust IAM access rules designed to eradicate the reliance on static credentials. By enforcing short-lived, identity-centric access control for continuous delivery platforms, this system minimizes account compromise risks. Technical Procedure Dynamic Caller Identification: Utilized the aws_caller_identity data source to programmatically determine context-aware account configuration details at runtime. Least Privilege Identity Mapping: Configured highly constrained IAM resource definitions (aws_iam_role) mapped strictly to deployment workflows.

Pipeline Persona Isolation: Implemented the short-lived "SaaS-Pipeline-Deployment-Role" explicitly assigned to automate remote deployments through restricted execution runners (GitLab CI/GitHub Actions).Validation Routine: Executed localized infrastructure testing using terraform init and terraform validate pipelines to guarantee zero configuration conflicts before live runtime deployment.Business & Security SignificanceStatic Credential Elimination: Removes long-lived keys completely from the development workflow. Since external build environments utilize temporary session profiles instead, a compromise of external runners leaves adversaries with immediately expired tokens.

Metadata Service Hardening: Prevents environment mapping exploitation by wrapping pipeline processes with identity-centric parameters, stopping dangerous lateral resource expansion if single assets become insecure.
