This check tries to determine if the project runs tests before pull requests are merged.
Running tests helps developers catch mistakes early on. A low score is considered 'Low' risk.
The check works by looking for a set of CI-system names in GitHub `CheckRuns` and `Statuses` among the recent commits (~30). A CI-system is considered well-known if its name contains any of the following: appveyor, buildkite, circleci, e2e, github-actions, jenkins, mergeable, test, travis-ci. A project may meet this criterion yet have a failing scorecard report; there are many ways to implement this criterion, and it's challenging for an automated tool (like scorecard) to detect them all. If a project's system was not detected and you think it should be, please [open an issue in the scorecard project](https://github.com/ossf/scorecard/issues/new/choose).

**Remediation steps**
- Check-in scripts that run all the tests in your repository.
- Integrate those scripts with a CI/CD platform that runs it on every pull request (e.g. [GitHub Actions](https://docs.github.com/en/actions/learn-github-actions/introduction-to-github-actions), [Prow](https://github.com/kubernetes/test-infra/tree/master/prow), etc).

This check tries to determine if the project has a set of contributors from multiple organizations (e.g., companies).
Low score has 'Low' risk.
Some projects cannot meet this requirement. Obviously projects with only one active participant cannot meet it. Many projects have a narrow scope and may not be able to attract the interest of multiple organizations. See [Code Reviews](#code-reviews) for added notes about projects with a small number of participants.
The check works by looking at the authors of recent commits and checking the `Company` field on the GitHub user profile. A contributor must have at least 5 commits in the last 30 commits. The highest score is achieved when there are contributors from at least 3 different companies in the last 30 commits.

**Remediation steps**
- There is *NO* remediation work needed here. This is to provide some insights on which organization(s) have contributed to the project and making trust decisions based on that. But you can ask your contributors to join their respective organizations.

It's important that the project provide an easy way to download, install, update, and uninstall the software. It's particularly important to make it easy for users to receive security patches as updates.
This is often done by creating a "package" that is easy to install and uninstall by a package manager. Many program language ecosystems have a generally-used packaging format supported by a language-level package manager tool and public package repository. Many operating system platforms also have at least one package format, tool, and public repository (in some cases the source repository generates system-independent source packages, which are then used by others to generate system executable packages). Container images are yet another way to package software. In some situations packaging is not sensible, but it's wise to package software in so many circumstances that it's worth checking for it.
A low score is considered `Medium` risk.
The check currently looks for [GitHub packaging workflows]( https://docs.github.com/en/packages/learn-github-packages/publishing-a-package) and language-specific GitHub Actions that upload the package to a corresponding hub, e.g., [Npm](https://www.npmjs.com/). There is a plan to add better support to query package manager hubs directly in the future, e.g., for [Npm](https://www.npmjs.com/), [PyPi](https://pypi.org/). A project may meet this criterion yet have a failing scorecard report; some widely-used tools are relatively easy to detect, but it's challenging for an automated tool (like scorecard) to detect them all. If scorecard fails to detect the way you publish a package and you think scorecard should support your use case, please [open an issue in the scorecard project](https://github.com/ossf/scorecard/issues/new/choose).

**Remediation steps**
- Publish your project as a [downloadable package](https://docs.github.com/en/packages/learn-github-packages/publishing-a-package).
- Use a GitHub action to release your package to language-specific hubs.
- Publish your project as a downloadable package, e.g., if hosted on GitHub, use [GitHub's mechanisms for publishing a package]](https://docs.github.com/en/packages/learn-github-packages/publishing-a-package).
- If hosted on GitHub, use a GitHub action to release your package to language-specific hubs.

## Pinned-Dependencies

This check tries to determine if the project is an application that has declared and pinned its dependencies. A "pinned dependency" is a dependency that is explicitly set to a specific version instead of allowing a range of versions. If this project is a library (not an application), this check should automatically pass (but see limitations below).
It's important for applications to pin dependencies to ensure that checking and deployment are all done with the same software, reducing deployment risks, simplifying debugging, and enabling reproducibility. In some cases pinning dependencies can help mitigate compromised dependencies from undermining the security of the project (in the case where you've evaluated the pinned dependency, you are confident it's not compromised, and a later version is released that is compromised). In particular, pinning dependencies is one way to [counter dependency confusion (aka substitution) attacks](https://azure.microsoft.com/en-us/resources/3-ways-to-mitigate-risk-using-private-package-feeds/). In a dependency confusion attack, an application uses multiple feeds to acquire software packages (a "hybrid configuration"), and attackers can fool the user into using a malicious package via a feed that was not expected for that package. A risk of pinning dependencies is that it can inhibit software updates (e.g., because of a security vulnerability or because the pinned version is compromised); this can be mitigated by [having applications and *not* libraries pin to specific versions](https://jbeckwith.com/2019/12/18/package-lock/), using automated tools to notify applications when their dependencies are outdated, and by applications that *do* pin dependencies update quickly. Low score is therefore considered `Medium` risk.
The checks works by (1) looking for the following files in the root directory: go.mod, go.sum (Golang), package-lock.json, npm-shrinkwrap.json (Javascript), requirements.txt, pipfile.lock (Python), gemfile.lock (Ruby), cargo.lock (Rust), yarn.lock (package manager), composer.lock (PHP), vendor/, third_party/, third-party/; (2) looks for unpinned dependencies in Dockerfiles, shell scripts and GitHub workflows.

It does not currently support other source hosting repositories (forges) other than GitHub.
*Limitations:* This check should only apply to applications, as libraries shouldn't normally have enforced pinned dependencies. Unfortunately, Scorecard currently can't detect if a project is a library or application. Even when [application detection is added](https://github.com/ossf/scorecard/issues/689), it's always possible for an automated tool like Scorecard to incorrectly categorize software (especially in projects that include both libraries and applications).
You can learn more about dependencies for projects on GitHub using [GitHub dependency graph](https://docs.github.com/en/code-security/supply-chain-security/understanding-your-software-supply-chain/about-the-dependency-graph).

**Remediation steps**
- First, determine if your project is producing a library or application. If it is a library, then generally you don't want to pin dependencies of library users. If your project is producing an application, consider the remediations below.

Attackers may use a compromised token with write access to push malicious code into the project. A low score is therefore considered `High` risk.
For each workflow yaml file, the check looks for the permission definitions. To obtain the highest score, the permissions should be set as read-only at the [top level](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#permissions) and the required write permissions should be declared at the [run-level](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idpermissions). The check cannot detect if the "read-only" GitHub permission settings is enabled, as there is no API available.
