## プロジェクトの歴史と使われ方

Terrascan is an open-source static analyzer for Infrastructure as Code that checks cloud and Kubernetes configuration before deployment. Its official README describes scanning for misconfigurations, posture drift, security vulnerabilities, and compliance violations, with local CLI and CI/CD integration workflows.

### プロジェクトの歴史

The project originated under Accurics and later moved under Tenable ownership, as reflected by changelog links that compare older releases under github.com/accurics/terrascan and later releases under github.com/tenable/terrascan. The current official repository is archived and states that it is no longer maintained.

### 採用の歴史

Terrascan became a package-manager-friendly IaC security tool because it distributed native release binaries, Docker images, and package recipes. The README documents Homebrew installation, AUR installation, and Docker usage, while the input metadata also lists MacPorts, Nix, and Scoop packages.

### 使われ方

In the package-nerd niche, Terrascan was used as a local scanner in developer workstations and CI jobs before Terraform, Kubernetes, Helm, Kustomize, CloudFormation, ARM, Dockerfile, or GitHub infrastructure changes were applied. Its value was the ability to run policy checks from a normal shell command without adopting a hosted platform first.

### パッケージ好きにとっての重要性

Terrascan is significant as part of the early wave of IaC security CLIs that package managers made easy to slot into pre-commit hooks, CI images, and ephemeral developer machines. Its archived status is now part of its history: packages may remain useful for reproducing older pipelines, but new deployments need to account for maintenance risk.

### タイムライン

- 2020: v1.1.0 appears in the official changelog on September 16, 2020.
- 2021-2022: Changelog links show releases under the Accurics repository path.
- 2022: Later changelog entries move to the Tenable repository path.
- 2023: v1.18.3 appears in the official changelog on August 3, 2023.
- 2024: GitHub page lists v1.19.9 as latest release on September 18, 2024.
- 2026: Official repository is archived and marked no longer maintained.

### Related projects

- Terrascan sits in the same IaC and cloud-security package niche as Terraform policy scanners, Kubernetes manifest linters, and CI security gates.
