Terraform, CloudFormation, and Pulumi hardening: state as a secret store, pinned providers and modules, encryption and network defaults, drift, and the privilege of the pipeline that applies the plan. Use when generating infrastructure code, reviewing IaC changes in a pull request, configuring a state backend, or setting up a new cloud account or workspace.

# Infrastructure-as-Code Security

## Rules (for AI agents)

### ALWAYS
- Treat the **state file as a secret store**. Every value that passes through
  Terraform — a generated password, an RDS master credential, a private key, the
  contents of a data source — is written to state in plaintext. `sensitive = true`
  only hides a value from CLI output; it changes nothing about what is stored. So
  read access to the backend is read access to those secrets, and the backend's
  access policy has to be written on that basis.
- Configure a **remote backend** with encryption at rest, state locking, and
  versioning. Prefer the backend's own locking where it exists — recent Terraform
  supports S3-native locking, so a separate DynamoDB lock table is no longer required
