## プロジェクトの歴史と使われ方

terraform-iam-policy-validator is an AWS Labs security CLI, installed as `tf-policy-validator`, that checks IAM policies extracted from Terraform plan output with IAM Access Analyzer validation and custom policy checks.

### プロジェクトの歴史

The awslabs/terraform-iam-policy-validator repository was created on GitHub in August 2022. Its README describes a command-line tool that parses Terraform templates for IAM identity-based and resource-based policies, then runs them through IAM Access Analyzer policy validation checks and optional custom policy checks.

### 採用の歴史

The project is narrower than general Terraform linters because it focuses specifically on AWS IAM policy semantics. The input package facts list Homebrew and Nix packaging, while the official README documents Python installation with `pip install tf-policy-validator`, indicating use both as a Python CLI and as a packaged security tool.

### 使われ方

The documented workflow is to run Terraform, convert a plan to JSON with `terraform show -json`, and pass that file to `tf-policy-validator validate` with an AWS region and config file. The tool can fail a pipeline when findings of selected severity levels are treated as blocking.

The README also documents custom checks for no-new-access, access-not-granted, and no-public-access. Because those checks call AWS IAM Access Analyzer APIs through boto3, the tool uses normal AWS credential resolution, including environment variables, shared credentials, AWS config, assume-role providers, and EC2 instance metadata.

### パッケージ好きにとっての重要性

For package-manager users, terraform-iam-policy-validator represents the compliance side of Terraform packaging: it is a standalone executable meant to be dropped into CI after `terraform plan`, with policy behavior controlled by command flags and config files. Its importance is strongest in AWS-heavy shops that want IAM policy review before apply.

### タイムライン

- 2022: GitHub repository created.
- 2024: v0.0.6 and v0.0.7 releases published.
- 2024: v0.0.8 release added custom-check changes including check-no-public-access.
- 2025: v0.0.9 listed as the latest GitHub release during research.

### Related projects

- The README ties the tool to AWS IAM Access Analyzer, boto3 credential handling, Terraform plan JSON, and AWS sample material for IAM Access Analyzer custom policy checks.
