Reposaur是一款针对开发平台和开源项目的合规性检测工具,在该工具的帮助下,广大研究人员可以直接使用预定义或自定义的策略来对目标项目或代码进行审核跟验证,并对数据和配置进行合规性检测。因此,Reposaur能够确保代码库中每一位代码贡献者都能够符合特定的安全标准或最佳实践准则。
当前版本的Reposaur支持GitHub和GitLab,随后将添加对Gitea的支持。
1、使用了Rego策略语言实现自定义策略;
2、提供了简单、易于使用的命令行接口;
3、支持使用简单的SDK进行扩展(Go编写);
4、报告遵循标准的SARIF格式,便于与不同系统集成;
5、可以对策略进行单元测试,确保它们按预期工作;
6、支持与主流开发平台集成;
7、支持使用SDK轻松集成新平台;
广大研究人员可以使用下列命令将该项目源码克隆至本地:
git clone https://github.com/reposaur/reposaur.git
$ brew install reposaur/tap/reposaur
广大研究人员可以直接从该项目的Releases页面下载.deb、.rmp或.apk包,然后使用特定的工具来安装它们。
$ go install github.com/reposaur/reposaur/cmd/[email protected]
$ curl -o- https://raw.githubusercontent.com/reposaur/reposaur/main/install.sh | bash
策略可以通过多个模块(文件)进行组合,必须符合同一命名空间(包),每一个模块可以定义多个规则。
下面的演示中,我们将通过一个github.repository命名空间下的单一模块进行演示。命名空间非常重要,因为Reposaur需要通过它来判断要对目标数据执行哪种规则:
package github.repository
接下来就要定义一个规则来获取默认的分支保护数据了,GitHub返回的数据不包含这部分内容,因此我们还需要添加额外的请求来获取:
protection = data {
resp := github.request("GET /repos/{owner}/{repo}/branches/{branch}/protection", {
"owner": input.owner.login,
"repo": input.name,
"branch": input.default_branch,
})
resp.status == 200
data := resp.body
}
结果如下所示:
violation_default_branch_not_protected {
not protection
}
接下来,我们可以通过下列规则来检测默认分支是否启用了其他保护策略:
violation_default_branch_pull_not_required {
not protection.required_pull_request_reviews
}
violation_default_branch_approvals_not_required {
not protection.required_pull_request_reviews.required_approving_review_count
}
violation_default_branch_approvals_not_required {
protection.required_pull_request_reviews.required_approving_review_count < 1
}
violation_default_branch_code_owners_reviews_not_required {
not protection.required_pull_request_reviews.require_code_owner_reviews
}
violation_default_branch_status_checks_not_required {
not protection.required_status_checks
}
violation_default_branch_up_to_date_not_required {
not protection.required_status_checks.strict
}
整合所有策略之后,我们的自定义策略将如下所示:
package github.repository
protection = data {
resp := github.request("GET /repos/{owner}/{repo}/branches/{branch}/protection", {
"owner": input.owner.login,
"repo": input.name,
"branch": input.default_branch,
})
resp.status == 200
data := resp.body
}
violation_default_branch_not_protected {
not protection
}
violation_default_branch_pull_not_required {
not protection.required_pull_request_reviews
}
violation_default_branch_approvals_not_required {
not protection.required_pull_request_reviews.required_approving_review_count
}
violation_default_branch_approvals_not_required {
protection.required_pull_request_reviews.required_approving_review_count < 1
}
violation_default_branch_code_owners_reviews_not_required {
not protection.required_pull_request_reviews.require_code_owner_reviews
}
violation_default_branch_status_checks_not_required {
not protection.required_status_checks
}
violation_default_branch_up_to_date_not_required {
not protection.required_status_checks.strict
}
现在,我们就可以使用自定义策略来对真实场景中的数据进行合规性检测了。
下列命令可以单独对一个项目代码库执行检测:
$ gh api /repos/reposaur/test | rsr exec
或者,也可以对一个组织中的所有代码库进行检测:
$ gh api /orgs/reposaur | rsr exec
工具执行完毕后,将生成如下所示的SARIF报告:
