+
+Follow the [principle of least privilege](https://www.cisa.gov/uscert/bsi/articles/knowledge/principles/least-privilege)
+for your CI configuration.
+
+If you run CI via GitHub Actions, a non-privileged environment is a workflow **without** access to
+GitHub secrets and with non-write permissions defined, such as `permissions: read-all`, `permissions:`,
+`contents: none`, `contents: read`. For more information about permissions, refer to the [official documentation](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token). 
+
+You may install the [OpenSSF Scorecard Action](https://github.com/ossf/scorecard-action)
+to flag non-read permissions on your project.

+#### Lockfiles and commands
+
+Certain `npm` commmands treat the lockfiles as read-only, while others do not.
+
+The following commands treat the lock file as read-only:
+
+1. [`npm ci`](https://docs.npmjs.com/cli/v8/commands/npm-ci), used to
+   install a project and its dependencies,
+
+1. [`npm install-ci-test`](https://docs.npmjs.com/cli/v8/commands/npm-install-ci-test),
+   used to install a project and run tests.
+
+The following commands ***do not*** treat the lock file as read-only, may fetch / install
+unpinned dependencies and update the lockfiles:
+
+1. `npm install`, `npm i`, `npm install -g`
+
+1. `npm update`
+
+1. `npm install-test`
+
+1. `npm pkg set` and `npm pkg delete`
+
+1. `npm exec`, `npx`
+
+1. `npm set-script`
+
 **Recommendations:**

    projects. Use the official [Creating a package.json

+   install --save <dep-name>`](https://docs.npmjs.com/cli/v8/commands/npm-install)

+1. If you need to run a standalone CLI package from the registry, ensure the package is a part of
+   the dependencies defined in your project via the `package.json` file, prior to
+   being installed at build-time in your CI or otherwise automated environment.
+
+1. Developers should declare and commit a lockfile for ***all*** their
+   projects. The reasoning is that this lockfile will provide the benefits of
+   [Reproducible installation](#reproducible-installation)
+   by default for privileged environments (project developers' machines,
+   CI, production or other environments with access to sensitive data, 
+   such as secrets, PII, write/push permission to the repository, etc).
+   
+   When running tests locally, developers should use commands that treat a lockfile
+   as read-only (see [Lockfiles and commands](#lockfiles-and-commands)), unless they
+   are intentionally adding / removing a dependency.
