Pinned Dependencies

GitHub Action tags and Docker tags are mutatble. This poses a security risk. GitHub's Security Hardening guide recommends pinning actions to full length commit.

Keeping your actions up to date with Dependabot

With Dependabot version updates, when Dependabot identifies an outdated dependency, it raises a pull request to update the manifest to the latest version of the dependency. This is recommended by GitHub as well as The Open Source Security Foundation (OpenSSF).

Secure Dockerfiles

Pin image tags to digests in Dockerfiles. With the Docker v2 API release, it became possible to use digests in place of tags when pulling images or to use them in FROM lines in Dockerfiles.
