This module focuses on the most sensitive artifact in your Infrastructure as Code workflow: the Terraform state file. You will learn why state files contain plaintext credentials, how state leakage occurs through version control and CI/CD logs, and how to architect secure remote backends with encryption, locking, and strict access controls. We will cover Terraform's sensitive value handling, provider-level secret injection, and the safe use of HashiCorp Vault or AWS Secrets Manager instead of hardcoded values and .tfvars files. The module culminates in a hands-on guided lab where you will audit a leaking state configuration, migrate to a hardened remote backend, and remediate exposed credentials.
