Installation

1. You can download the latest legitify release from https://github.com/Legit-Labs/legitify/releases, each archive contains:

• Legitify binary for the desired platform
• Built-in policies provided by Legit Security

1. From source with the following steps:

git clone git@github.com:Legit-Labs/legitify.git
go run main.go analyze ...

Requirements

1. To get the most of legitify, you need to be an owner of at least one GitHub organization. Otherwise, you can still use the tool if you're an admin of at least one repository, in which case you'll be able to see only repository-related policies results.
2. legitify requires a GitHub personal access token (PAT) to analyze your resources successfully, which can be either provided as an argument (-t) or as an environment variable ($GITHUB_ENV). The PAT needs the following scopes for full analysis:

admin:org, read:enterprise, admin:org_hook, read:org, repo, read:repo_hook

See Creating a Personal Access Token for more info.

Usage

GITHUB_TOKEN=<your_token> legitify analyze

By default, legitify will check the policies against all your resources (organizations, repositories, members, actions).

You can control which resources will be analyzed with command-line flags namespace and org:

• --namespace (-n): will analyze policies that relate to the specified resources
• --org: will limit the analysis to the specified organizations

GITHUB_TOKEN=<your_token> legitify analyze --org org1,org2 --namespaces organization,member

The above command will test organization and member policies against org1 and org2.

Namespaces

Namespaces in legitify are resources that are collected and run against the policies. Currently, the following namespaces are supported:

1. organization - organization level policies (e.g., "Two-Factor Authentication Is Not Enforced for the Organization")
2. actions - organization GitHub Actions policies (e.g., "GitHub Actions Runs Are Not Limited To Verified Actions")
3. member - organization members policies (e.g., "Stale Admin Found")
4. repository - repository level policies (e.g., "Code Review By At Least Two Reviewers Is Not Enforced")

By default, legitify will analyze all namespaces. You can limit only to selected ones with the --namespace flag, and then a comma seperated list of the selected namespaces.

Output Options

By default, legitify will output the results in a human-readable format. This includes the list of policy violations listed by severity, as well as a summary table that is sorted by namespace.

Output Formats

Using the --output-format (-f) flag, legitify supports outputing the results in the following formats:

1. human-readable - Human-readable text (default).
2. json - Standard JSON.

Output Schemes

Using the --output-scheme flag, legitify supports outputing the results in different grouping schemes. Note: --output-format=json must be specified to output non-default schemes.

1. flattened - No grouping; A flat listing of the policies, each with its violations (default).
2. group-by-namespace - Group the policies by their namespace.
3. group-by-resource - Group the policies by their resource e.g. specific organization/repository.
4. group-by-severity - Group the policies by their severity.

Output Destinations

• --output-file - full path of the output file (default: no output file, prints to stdout).
• --error-file - full path of the error logs (default: ./errors.log).

Coloring

When outputing in a human-readable format, legitify support the conventional --color[=when] flag, which has the following options:

• auto - colored output if stdout is a terminal, uncolored otherwise (default).
• always - colored output regardless of the output destination.
• none - uncolored output regardless of the output destination.

Misc

• Use the --failed-only flag to filter-out passed/skipped checks from the result.

Scorecard Support

scorecard is an OSSF's open-source project:

Scorecards is an automated tool that assesses a number of important heuristics ("checks") associated with software security and assigns each check a score of 0-10. You can use these scores to understand specific areas to improve in order to strengthen the security posture of your project. You can also assess the risks that dependencies introduce, and make informed decisions about accepting these risks, evaluating alternative solutions, or working with the maintainers to make improvements.

legitify supports running scorecard for all of the organization's repositories, enforcing score policies and showing the results using the --scorecard flag:

• no - do not run scorecard (default).
• yes - run scorecard and employ a policy that alerts on each repo score below 7.0.
• verbose - run scorecard, employ a policy that alerts on each repo score below 7.0, and embed its output to legitify's output.

legitify runs the following scorecard checks:

Check	Public Repository	Private Repository
Security-Policy	V
CII-Best-Practices	V
Fuzzing	V
License	V
Signed-Releases	V
Branch-Protection	V	V
Code-Review	V	V
Contributors	V	V
Dangerous-Workflow	V	V
Dependency-Update-Tool	V	V
Maintained	V	V
Pinned-Dependencies	V	V
SAST	V	V
Token-Permissions	V	V
Vulnerabilities	V	V
Webhooks	V	V

Policies

legitify comes with a set of policies in the policies/github directory. These policies are documented here.

In addition, you can use the --policies-path (-p) flag to specificy a custom directory for OPA policies.
