This project is maintained by members of the Securing Critical Projects WG.

1. Generate a criticality score for every open source project.

2. Create a list of critical projects that the open source community depends on.

3. Use this data to proactively improve the security posture of these critical projects.

A project's criticality score defines the influence and importance of a project. It is a number between 0 (least-critical) and 1 (most-critical). It is based on the following algorithm by Rob Pike:

We use the following default parameters to derive the criticality score for an open source project:

NOTE:

• You can override those defaut values at runtime as described below.
• We are looking for community ideas to improve upon these parameters.
• There will always be exceptions to the individual reasoning rules.

$ go install github.com/ossf/criticality_score/v2/cmd/criticality_score@latest

$ export GITHUB_TOKEN=...         # requires a GitHub token to work
$ gcloud auth login --update-adc  # optional, add -depsdev-disable to skip

The score can be changed by using the -scoring-config parameter and supplying a different configuration file to specify how the score is calculated.

By default the original_pike.yml configuration is used to calculate the score. However, other config files can be supplied to produce different scores. See config/scorer for more.

Feel free to copy one of the configurations and adjust the weights and thresholds to suit your needs.

Before running criticality score, you need to:

• For GitHub repos, you need to create a GitHub access token and set it in environment variable GITHUB_AUTH_TOKEN. This helps to avoid the GitHub's api rate limits with unauthenticated requests.

# For posix platforms, e.g. linux, mac:
export GITHUB_AUTH_TOKEN=<your access token>

# For windows:
set GITHUB_AUTH_TOKEN=<your access token>

There are three formats currently: text, json, and csv. Others may be added in the future.

These may be specified with the -format flag.

The criticality score project also has other commands for generating and working with criticality score data.

• enumerate_github: a tool for accurately collecting a set of GitHub repos with a minimum number of stars
• collect_signals: a worker for collecting raw signals at scale by leveraging the Scorecard project's infrastructure.
• scorer: a tool for recalculating criticality scores based on an input CSV file.

If you're interested in seeing a list of critical projects with their criticality score, we publish them in csv format and a BigQuery dataset.

This data is generated using a production instance of the criticality score project running in GCP. Details for how this is deployed can be found in the infra directory.

NOTE: Currently, these lists are derived from projects hosted on GitHub ONLY. We do plan to expand them in near future to account for projects hosted on other source control systems.

The data is available on Google Cloud Storage and can be downloaded via:

• web browser: commondatastorage.googleapis.com/ossf-criticality-score/index.html
• gsutil command-line tool: gsutil ls gs://ossf-criticality-score/

This data is available in the public BigQuery dataset.

With a GCP account you can run queries across the data. For example, here is a query returning the top 100 repos by score:

  SELECT repo.url, default_score
    FROM `openssf.criticality_score_cron.criticality-score-v0-latest`
ORDER BY default_score DESC
   LIMIT 100;

If you want to get involved or have ideas you'd like to chat about, we discuss this project in the Securing Critical Projects WG meetings.
