收集 Zscaler DLP 日志

支持的平台：

Google SecOps SIEM

本文档介绍了如何通过设置 Google Security Operations Feed 导出 Zscaler DLP 日志，以及日志字段如何映射到 Google SecOps Unified Data Model (UDM) 字段。

如需了解详情，请参阅将数据注入 Google SecOps 概览。

典型部署包括 Zscaler DLP 和配置为将日志发送到 Google SecOps 的 Google SecOps Webhook Feed。每个客户部署都可能有所不同，并且可能更复杂。

部署包含以下组件：

Zscaler DLP：您从中收集日志的平台。
Google SecOps Feed：从 Zscaler DLP 中提取日志并将日志写入 Google SecOps 的 Google SecOps Feed。
Google Security Operations：保留并分析日志。

注入标签用于标识将原始日志数据标准化为结构化 UDM 格式的解析器。本文档中的信息适用于带有 ZSCALER_DLP 标签的解析器。

准备工作

确保您满足以下前提条件：

访问 Zscaler Internet Access 控制台的权限。如需了解详情，请参阅 Secure Internet and SaaS Access ZIA 帮助。
Zscaler DLP 2024 或更高版本
部署架构中的所有系统都使用世界协调时间 (UTC) 时区进行配置。
在 Google Security Operations 中完成 Feed 设置所需的 API 密钥。如需了解详情，请参阅设置 API 密钥。

设置 Feed

如需配置此日志类型，请按以下步骤操作：

依次前往 SIEM 设置 > Feed。
点击添加新 Feed。
点击 Zscaler Feed 包。
找到所需的日志类型，然后点击添加新 Feed。
输入以下输入形参的值：
- 来源类型：Webhook（推荐）
- 拆分定界符：用于分隔日志行的字符。如果不使用定界符，请留空。
高级选项
- Feed 名称：用于标识 Feed 的预填充值。
- 资产命名空间：与 Feed 关联的命名空间。
- 提取标签：应用于相应 Feed 中所有事件的标签。
点击创建 Feed。

如需详细了解如何为相应产品系列中的不同日志类型配置多个 Feed，请参阅按产品配置 Feed。

设置 Zscaler DLP

在 Zscaler Internet Access 控制台中，依次前往 Administration > Nanolog Streaming Service > Cloud NSS Feeds。
点击 Add Cloud NSS Feed。
在Feed Name 字段中输入 Feed 的名称。
在 NSS 类型中选择 NSS for Web。
从状态列表中选择相应状态，以启用或停用 NSS Feed。
将 SIEM 速率菜单中的值保留为无限制。如需因许可或其他限制而抑制输出流，请更改该值。
在 SIEM 类型列表中，选择其他。
在 OAuth 2.0 身份验证列表中，选择已停用。
根据 SIEM 的最佳实践，在最大批次大小中输入单个 HTTP 请求载荷的大小限制（例如 512 KB）。
在“API 网址”中，输入 Chronicle API 端点的 HTTPS 网址，格式如下：
```
https://<CHRONICLE_REGION>-chronicle.googleapis.com/v1alpha/projects/<GOOGLE_PROJECT_NUMBER>/locations/<LOCATION>/instances/<CUSTOMER_ID>/feeds/<FEED_ID>:importPushLogs
```
- CHRONICLE_REGION：Google SecOps 实例托管的区域（例如美国）。
- GOOGLE_PROJECT_NUMBER： Google Cloud 项目编号。
- LOCATION：Google SecOps 区域（例如美国）。
- CUSTOMER_ID：Chronicle 客户 ID。
- FEED_ID：在创建的新 Webhook 上显示的 Feed 界面中的 Feed ID。
API 网址示例：
```
https://us-chronicle.googleapis.com/v1alpha/projects/12345678910/locations/US/instances/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/feeds/yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy:importPushLogs
```
点击添加 HTTP 标头，然后添加以下格式的 HTTP 标头：
- Header 1：Key1： X-goog-api-key 和 Value1：在 Google Cloud的 API 凭据中生成的 API 密钥。
- Header 2：Key2： X-Webhook-Access-Key 和 Value2：在 Webhook 的“SECRET KEY”（密钥）中生成的 API 密钥。
从日志类型列表中选择 Endpoint DLP。
在 Feed 输出类型列表中，选择 JSON。
停用 JSON 数组表示法。
将Feed 转义字符设置为 , \ "。
如需向 Feed 输出格式添加新字段，请在 Feed 输出类型列表中选择自定义。

复制粘贴Feed 输出格式，然后添加新字段。确保键名与实际字段名称一致。

以下是默认的Feed 输出格式：

\{ "sourcetype" : "zscalernss-edlp", "event" :\{"time":"%s{time}","recordid":"%d{recordid}","login":"%s{user}","dept":"%s{department}","filetypename":"%s{filetypename}","filemd5":"%s{filemd5}","dlpdictnames":"%s{dlpdictnames}","dlpdictcount":"%s{dlpcounts}","dlpenginenames":"%s{dlpengnames}","channel":"%s{channel}","actiontaken":"%s{actiontaken}","severity":"%s{severity}","rulename":"%s{triggeredrulelabel}","itemdstname":"%s{itemdstname}"\}\}

在时区列表中，为输出文件中的时间字段选择时区。默认情况下，时区设置为组织的时区。
查看配置的设置。
点击保存以测试连接。如果连接成功，系统会显示一个绿色对勾，并附带消息 Test Connectivity Successful: OK (200)。

如需详细了解 Google SecOps Feed，请参阅 Google SecOps Feed 文档。如需了解每种 Feed 类型的要求，请参阅按类型配置 Feed。

如果您在创建 Feed 时遇到问题，请与 Google SecOps 支持团队联系。
