软件供应链健康度评估之scorecard

Scorecard介绍

Scorecard是一个自动化工具，评估开源项目的健康度。Scorecard通过评估与开源项目安全性相关的一系列指标项，每项10分。可以使用这些评分来了解需要改进的具体领域，以增强项目的安全性。同时，还可以评估依赖项带来的安全风险，如接受这些风险、评估替代方案或与维护者合作进行改进。

注意：由于scorecard项目不断迭代更新，检测规则也在变化，本文有效时间为：2024年08月06日前后

支持Scorecard项目

Scorecard已在数千个项目上运行，以监控和跟踪安全指标。主要使用Scorecard的项目包括：

Tensorflow
Angular
Flutter
sos.dev
deps.dev

deps fastjson results

查看项目的评分

要查看Scorecard定期扫描的项目评分，请访问webviewer，并替换占位符文本为平台、用户/组织和存储库名称：https://scorecard.dev/viewer/?uri=<github_or_gitlab>.com/<user_name_or_org>/<repository_name>

例如：

https://scorecard.dev/viewer/?uri=github.com/alibaba/fastjson

fastjson score

公开数据

每周对被认为是最关键的100万个开源项目进行Scorecard扫描，并将结果发布在BigQuery公开数据集中。最新的结果可在BigQuery视图openssf:scorecardcron.scorecard-v2_latest中查看。

可以使用BigQuery Explorer查询数据，导航至Add Data > Star a project by name > 'openssf'。例如，可能会对项目评分随时间的变化感兴趣：

bigquery data query

SELECT date, score FROM `openssf.scorecardcron.scorecard-v2` WHERE repo.name="github.com/alibaba/fastjson" ORDER BY date ASC

bigquery data query demo

还可以使用bq工具将最新结果提取到Google Cloud Storage中：

# 获取最新的PARTITION_ID
bq query --nouse_legacy_sql 'SELECT partition_id FROM openssf.scorecardcron.INFORMATION_SCHEMA.PARTITIONS WHERE table_name="scorecard-v2" AND partition_id!="__NULL__" ORDER BY partition_id DESC LIMIT 1'
# 提取到GCS
bq extract --destination_format=NEWLINE_DELIMITED_JSON 'openssf:scorecardcron.scorecard-v2$<partition_id>' gs://bucket-name/filename-*.json

Scorecard 使用

Scorecard GitHub Action

使用Scorecard GitHub Action是最简单的方法，在拥有的GitHub项目上运行Scorecard。该Action在任何存储库更改时运行，并在维护者可以在存储库的安全标签中查看警报。有关更多信息，请参阅Scorecard GitHub Action安装说明。

Scorecard命令行

要在不拥有的项目上运行Scorecard扫描，请使用命令行界面安装选项。

安装

Docker

scorecard可以作为Docker容器使用：

docker pull gcr.io/openssf/scorecard:stable

要使用特定的scorecard版本（例如v3.2.1），请运行：

docker pull gcr.io/openssf/scorecard:v3.2.1

本地安装

自行编译，或者直接从release下载对应的二进制文件即可

make build

使用包管理器

包管理器

支持的分发版

命令

Nix

NixOS

nix-shell -p nixpkgs.scorecard

AUR

Arch Linux

yaourt install scorecard

Homebrew

macOS或Linux

brew install scorecard

获取github 授权 token

GitHub对未经认证的请求实施api速率限制。为了避免这些限制，必须在运行Scorecard之前对的请求进行认证。有两种方法可以认证的请求：创建GitHub个人访问令牌或创建GitHub App安装。

创建经典的GitHub个人访问令牌。创建个人访问令牌时，建议选择public_repo范围。

export GITHUB_AUTH_TOKEN=<your access token>

运行

若要在特定存储库上运行scorecard：

scorecard --repo=<repo_url>

例如：

scorecard --repo=https://github.com/alibaba/fastjson

在默认情况下，Scorecard会对所有检查运行。要运行特定检查，请使用：

scorecard --repo=<repo_url> --checks <check1,check2>

例如：

scorecard --repo=https://github.com/ossf/scorecard --checks Code-Review,Maintained

使用SARIF文件导出到GitHub Security 可以将Scorecard检查结果导出到GitHub Security工具（由GitHub Actions自动生成）。为此，使用--format参数生成一个SARIF文件并上传：

scorecard --repo=<repo_url> --format sarif > results.sarif
gh upload results.sarif

使用原始数据导出默认情况下，scorecard导出json格式的结果。可以使用以下参数导出结果：

scorecard --repo=<repo_url> --format json --show-details > results.json
