GitArmor is a handy tool that makes it easy to assess the secure setup of your developer platform.

GitArmor intuitively transforms the security requirements and controls for your DevOps implementation into policies as code and enables you to run the checks against your GitHub environment.​

Here’s how GitArmor can be a game changer for you:

1. Policy as Code - Transform your DevOps platform security policies into GitArmor yml files. Stored centrally, these policies can be enforced with on-demand or periodic checks across your GitHub Organization, helping you pinpoint and prioritize areas for improvement. 🔒
2. Security Assessments - Perfect for Security Teams, GitArmor facilitates the reconnaissance phase of whitebox penetration tests by running against a project or organization. Armed with insights from the reports, you can strategize and execute targeted attacks on identified misconfigurations. 🎯
3. Dev Team Setup - Ideal for startups, a small development team can utilize GitArmor along with the default policy to ensure their GitHub repositories and organization are securely configured. 🎛️

GitArmor also maps the checks against the SLSA.dev and MS DevOps threat matrix to provide a comprehensive security posture for your GitHub environment. The threats and controls are documented in:

• Repository Threats
• Organization Threats

Developed in TypeScript, GitArmor is designed for use either in a terminal (CLI) or as a GitHub Action.

Ready to get started with GitArmor? First, you'll need to either clone the repository or grab a release from our releases page.

Simply clone the repository:

gh repo clone gitarmor/gitarmor

Install the necessary dependencies using npm or yarn:

npm install

Create a .env file by using our sample configuration file .env.sample:

TOKEN=ghp_TKN
LEVEL=repository
REPO=repo-name
ORG=org-name
DEBUG=false
POLICIES_PATH=policies

where LEVEL is the scope of the checks:

• repository for repository-level checks
• organization for organization-level checks

Next, generate a Personal Access Token (PAT) from GitHub and input your settings into the .env file. Ensure your token has these permissions:

• repo: admin
• org: admin

The policies are written in YML and are stored in repository.yml and organization.yml files under the policies folder. Each policy file contains the checks for the respective scope.

• Repository Policies
• Organization Policies

The syntax for each policy can be found in the Repository Policy README and in the Organization Policy README

To start the GitArmor check, run:

npm run start

The results will be displayed in the standard output, with reports saved in both JSON and Markdown formats in the output-report.json and output-report.md files, respectively.

GitArmor is published to the GitHub Marketplace and can be easily setup as a new workflow or integrated into an existing GitHub Actions workflow.

jobs:
  run-gitarmor:
    runs-on: ubuntu-latest
...
    - name: Checkout policies
      uses: actions/checkout@v4
      with:
        sparse-checkout: policies
        repository: dcodx/gitarmor@main

    - name: Run GitArmor Action
      uses: dcodx/gitarmor@v1
      id: gitarmor
      #env:
      #   DEBUG: true
      with:
          repo: ${{ github.repository }}
          org: ${{ github.repository_owner }}
          token: ${{ TOKEN }}
          level: 'organization'
          policy-dir: './policies'

You can use the following example workflow files as inspiration for your own implementation:

• GitArmor workflow for on-demand scans
• GitArmor workflow for periodic scans

For the token we recommend using create-github-app-token and creating a GitHub App Installation Access Token.

The action will generate a report in the standard output, with reports saved in both JSON and Markdown formats in the output-report.json and output-report.md files, respectively.

In an Action run, it will also set-output of the two reports into check-results-text and check-results-json for further processing in following steps or other jobs.

Lastly will also print the markdown report as a Job Summary.

• Add Enterprise level checks
• Extend checks at the organization level
• Enhance our documentation
• Launch the GitArmor Bot to automatically enforce GitArmor policies
