收集 GitHub 审核日志

支持的平台：

本文档介绍了如何使用 Amazon S3 将 GitHub 审核日志注入到 Google Security Operations。解析器会尝试使用各种 Grok 模式从“message”字段中提取数据，同时处理 JSON 和非 JSON 格式。根据提取的“process_type”，它会使用 grok、kv 和其他过滤器应用特定的解析逻辑，将原始日志数据映射到统一数据模型 (UDM) 架构。

准备工作

请确保满足以下前提条件：

  • Google SecOps 实例。
  • 对具有企业主权限的 GitHub Enterprise Cloud 租户的特权访问权限。
  • 对 AWS（S3、IAM）的特权访问权限。

收集 GitHub Enterprise Cloud 前提条件（企业访问权限）

  1. 登录 GitHub Enterprise Cloud 管理控制台。
  2. 依次前往企业设置 > 设置 > 审核日志 > 日志流式传输。
  3. 确保您拥有企业所有者权限，可以配置审核日志流式传输。
  4. 复制以下详细信息并将其保存在安全的位置：
    • GitHub Enterprise 名称
    • 企业下的组织名称

为 Google SecOps 配置 AWS S3 存储桶和 Identity and Access Management

  1. 按照以下用户指南创建 Amazon S3 存储桶：创建存储桶
  2. 保存存储桶名称和区域以供日后参考（例如 github-audit-logs）。
  3. 按照以下用户指南创建用户：创建 IAM 用户。
  4. 选择创建的用户。
  5. 选择安全凭据标签页。
  6. 在访问密钥部分中，点击创建访问密钥。
  7. 选择第三方服务作为使用情形。
  8. 点击下一步。
  9. 可选：添加说明标记。
  10. 点击创建访问密钥。
  11. 点击下载 .CSV 文件，保存访问密钥和秘密访问密钥，以供日后参考。
  12. 点击完成。

为 GitHub S3 流式传输配置 IAM 政策

  1. 在 AWS 控制台中，依次前往 IAM > 政策 > 创建政策 > JSON 标签页。
  2. 复制并粘贴以下政策。

  3. 政策 JSON（如果您输入了其他存储桶名称，请替换 github-audit-logs）：

    {
"Version": "2012-10-17",
"Statement": [
    {
    "Sid": "AllowPutObjects",
    "Effect": "Allow",
    "Action": "s3:PutObject",
    "Resource": "arn:aws:s3:::github-audit-logs/*"
    }
]
}

  4. 依次点击下一步 > 创建政策。

  5. 为政策命名 GitHubAuditStreamingPolicy，然后点击创建政策。

  6. 返回到之前创建的 IAM 用户。

  7. 选择权限标签页。

  8. 依次点击添加权限 > 直接附加政策。

  9. 搜索并选择 GitHubAuditStreamingPolicy。

  10. 依次点击下一步 > 添加权限。

配置 GitHub Enterprise Cloud 审核日志流式传输

  1. 以企业所有者的身份登录 GitHub Enterprise Cloud。
  2. 点击您的个人资料照片，然后点击企业版设置。
  3. 在企业账号边栏中，依次点击设置 > 审核日志 > 日志流式传输。
  4. 选择配置信息流，然后点击 Amazon S3。
  5. 在身份验证下，点击访问密钥。
  6. 提供以下配置详细信息：
    • 区域：选择存储桶的区域（例如 us-east-1）。
    • 存储桶：输入要将数据流式传输到的存储桶的名称（例如 github-audit-logs）。
    • 访问密钥 ID：输入 IAM 用户的访问密钥 ID。
    • Secret Key（密钥）：输入 IAM 用户的密钥。
  7. 点击检查端点，验证 GitHub 是否可以连接到 Amazon S3 端点并向其写入数据。
  8. 成功验证端点后，点击保存。

为 Google SecOps 创建只读 IAM 用户和密钥

  1. 依次前往 AWS 控制台> IAM > 用户 > 添加用户。
  2. 点击 Add users（添加用户）。
  3. 提供以下配置详细信息：
    • 用户：输入 secops-reader。
    • 访问类型：选择访问密钥 - 以程序化方式访问。
  4. 点击创建用户。
  5. 附加最低限度的读取政策（自定义）：依次点击用户 > secops-reader > 权限 > 添加权限 > 直接附加政策 > 创建政策。

  6. JSON：

    {
"Version": "2012-10-17",
"Statement": [
    {
    "Effect": "Allow",
    "Action": ["s3:GetObject"],
    "Resource": "arn:aws:s3:::github-audit-logs/*"
    },
    {
    "Effect": "Allow",
    "Action": ["s3:ListBucket"],
    "Resource": "arn:aws:s3:::github-audit-logs"
    }
]
}

  7. 名称 = secops-reader-policy。

  8. 依次点击创建政策 > 搜索/选择 > 下一步 > 添加权限。

  9. 为 secops-reader 创建访问密钥：安全凭据 > 访问密钥 > 创建访问密钥 > 下载 .CSV（您需要将这些值粘贴到 Feed 中）。

在 Google SecOps 中配置 Feed 以注入 GitHub 日志

  1. 依次前往 SIEM 设置 > Feed。
  2. 点击 + 添加新 Feed。
  3. 在Feed 名称字段中，输入 Feed 的名称（例如 GitHub audit logs）。
  4. 选择 Amazon S3 V2 作为来源类型。
  5. 选择 GitHub 作为日志类型。
  6. 点击下一步。
  7. 为以下输入参数指定值：
    • S3 URI：s3://github-audit-logs/
    • 来源删除选项：根据您的偏好选择删除选项。
    • 文件存在时间上限：包含在过去指定天数内修改的文件。默认值为 180 天。
    • 访问密钥 ID：有权访问 S3 存储桶的用户访问密钥。
    • 私有访问密钥：具有 S3 存储桶访问权限的用户私有密钥。
    • 资源命名空间：资源命名空间。
    • 注入标签：应用于相应 Feed 中事件的标签。
  8. 点击下一步。
  9. 在最终确定界面中查看新的 Feed 配置，然后点击提交。
