收集 Microsoft Windows AD 日志

此文档包含以下信息：

• 部署架构和安装步骤，以及生成 Microsoft Windows Active Directory 事件的 Google Security Operations 解析器支持的日志所需的任何配置。如需大致了解 Google Security Operations 数据注入，请参阅将数据注入到 Google Security Operations。
• 有关解析器如何将原始日志中的字段映射到 Google Security Operations Unified Data Model 字段的信息。

根据您的部署架构，配置 Bindplane 代理或 NXLog 代理，以将 Microsoft Windows Active Directory 日志注入到 Google Security Operations 中。 我们建议您使用 Bindplane 代理将 Windows Active Directory 的日志转发到 Google Security Operations。

本文档中的信息适用于具有 WINDOWS_AD 注入标签的解析器。注入标签标识哪个解析器将原始日志数据标准化为结构化 UDM 格式。

准备工作

在配置 Bindplane 代理或 NXLog 代理之前，请完成以下任务：

• 将所有系统配置为使用世界协调时间 (UTC) 时区。
• 配置 Microsoft Windows AD 服务器。
• 查看支持的设备和版本。
• 查看支持的日志类型。

配置 Microsoft Windows AD 服务器

1. 在每个 Microsoft Windows Active Directory 服务器上，创建并配置 PowerShell 脚本以将日志数据保存到输出文件。Bindplane 代理或 NXLog 代理会读取输出文件。

   # Set the location where the log file will be written
   $OUTPUT_FILENAME="<Path_of_the_output_file>"
   
   If (Test-Path -Path $OUTPUT_FILENAME) { Remove-Item -path $OUTPUT_FILENAME -ErrorAction SilentlyContinue}
   
   # USER_CONTEXT: Gets all Active Directory users and their properties.
   Get-ADUser -Filter * -properties samAccountName | % { Get-ADUser $_.SamAccountName -properties * | ConvertTo-JSON -compress | Out-File -encoding utf8 $OUTPUT_FILENAME -Append }
   
   # ASSET_CONTEXT: Gets all Active Directory assets and their properties.
   Get-ADComputer -Filter * -properties samAccountName | % { Get-ADComputer $_.SamAccountName -properties * | ConvertTo-JSON -compress | Out-File -encoding utf8 $OUTPUT_FILENAME -Append }
   

2. 替换以下内容：

   • 将 $OUTPUT_FILENAME 的值替换为输出文件的位置。
   • 以 JSON 格式存储数据。
   • 将编码设置为 UTF-8。
   • 调用 Get-ADUser 和 Get-ADComputer cmdlet 时，请使用 -Filter 参数，而不是 -LDAPFilter 参数。

3. 创建运行脚本的周期性任务，以将数据提取并写入到输出文件。

   1. 打开“任务计划程序”应用。
   2. 点击创建任务。
   3. 输入任务的名称和说明。
   4. 选中以最高权限运行复选框，以确保检索所有数据。
   5. 在触发器标签页中，定义何时希望重复执行该任务。
   6. 在操作标签页中，添加新操作，并提供存储该脚本的文件的路径。

查看支持的设备和版本

Microsoft Windows Server 按以下版本发布：Foundation、Essentials、Standard 和 Datacenter。每个版本生成的日志事件架构没有区别。

Google Security Operations 解析器支持来自以下 Microsoft Windows 服务器版本的日志：

• Microsoft Windows Server 2019
• Microsoft Windows Server 2016
• Microsoft Windows Server 2012

Google Security Operations 解析器支持由 NXLog Community Edition 或 Enterprise Edition 收集的日志。

查看支持的日志类型

Google Security Operations 解析器将解析从用户上下文和资产上下文中检索的数据并对其进行标准化。它支持使用英语文本生成的日志，不支持使用非英语生成的日志。

配置 Bindplane 代理

我们建议您使用 Bindplane 代理将 Windows Active Directory 的日志转发到 Google Security Operations。

安装后，Bindplane 代理服务会显示为 Windows 服务列表中的 observIQ 服务。

1. 在每个 Windows Active Directory 服务器上安装 Bindplane 代理。如需详细了解如何安装 Bindplane 代理，请参阅 Bindplane 代理安装说明。

2. 创建一个包含以下内容的 Bindplane 代理配置文件：

   receivers:
     filelog:
       include: [ `FILE_PATH` ]
       operators:
         - type: json_parser
       start_at: beginning
     windowseventlog/activedirectoryservice:
       channel: Directory Service
       raw: true
   processors:
     batch:
   
   exporters:
     chronicle/activedirectory:
       endpoint: https://malachiteingestion-pa.googleapis.com
       creds: '{
       "type": "service_account",
       "project_id": "malachite-projectname",
       "private_key_id": `PRIVATE_KEY_ID`,
       "private_key": `PRIVATE_KEY`,
       "client_email":"`SERVICE_ACCOUNT_NAME`@malachite-`PROJECT_ID`.iam.gserviceaccount.com",
       "client_id": `CLIENT_ID`,
       "auth_uri": "https://accounts.google.com/o/oauth2/auth",
       "token_uri": "https://oauth2.googleapis.com/token",
       "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
       "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/`SERVICSERVICE_ACCOUNT_NAME`%40malachite-`PROJECT_ID`.iam.gserviceaccount.com",
       "universe_domain": "googleapis.com"
       }'
     log_type: 'WINDOWS_AD'
     override_log_type: false
     raw_log_field: body
     customer_id: `CUSTOMER_ID`
   
   service:
     pipelines:
       logs/ads:
         receivers:
           - filelog
           - windowseventlog/activedirectoryservice
         processors: [batch]
         exporters: [chronicle/activedirectory]
   

3. 替换以下内容：

   • FILE_PATH，其中包含配置 Microsoft Windows AD 服务器中提及的 PowerShell 脚本的输出已存储到的文件路径。

   • PRIVATE_KEY_ID、PRIVATE_KEY、SERVICSERVICE_ACCOUNT_NAME、PROJECT_ID、CLIENT_ID 和 CUSTOMER_ID，并使用从服务账号 JSON 文件（可从 Google Cloud下载）中获取的相应值。如需详细了解服务账号密钥，请参阅创建和删除服务账号密钥。

4. 如需启动 Bindplane（以前称为 observIQ）代理服务，请依次选择 Services > Extended > the observIQ Service > Start。

配置 NXLog 代理

下图展示了一个架构，其中安装了 NXLog 代理来收集 Microsoft Windows 事件并将其发送到 Google Security Operations。将此信息与您的环境进行比较，以确保已安装这些组件。您的部署可能与此架构不同，并且可能更复杂。

如果您使用的是 NXLog 代理，而不是 Bindplane 代理，请验证以下内容：

• 在运行 Active Directory 的每个 Microsoft Windows Server 上创建并配置 PowerShell 脚本，以收集 USER_CONTEXT 和 ASSET_CONTEXT 数据。如需了解详情，请参阅配置 Microsoft Windows AD 服务器。
• 每个 Microsoft Windows AD 服务器上安装了 NXLog，用于将数据发送到中央 Microsoft Windows 服务器或 Linux 服务器。
• Google Security Operations 转发器安装在中央 Microsoft Windows 服务器或 Linux 服务器上，用于将日志数据转发到 Google Security Operations。

配置 NXLog

1. 在 Windows Active Directory 服务器上运行的每个收集器上安装 NXLog 代理。该应用会将日志转发到中央 Microsoft Windows 或 Linux 服务器。如需了解详情，请参阅 NXLog 文档。

2. 为每个 NXLog 实例创建一个配置文件。使用 NXLog im_file 模块从文件中读取内容并将行解析为字段。使用 om_tcp 将数据转发到中央 Microsoft Windows 或 Linux 服务器。

   以下是 NXLog 配置示例。将 <hostname> 和 <port> 值替换为目标中央 Microsoft Windows 或 Linux 服务器的信息。在 <Input in_adcontext> 部分和 File 属性中，添加由 PowerShell 脚本写入的输出日志文件的路径。始终设置 DirCheckInterval 和 PollInterval。如果未定义，则 NXLog 每 1 秒轮询一次文件。

   define ROOT C:\Program Files\nxlog
   define ADCONTEXT_OUTPUT_DESTINATION_ADDRESS <hostname>
   define ADCONTEXT_OUTPUT_DESTINATION_PORT <port>
   
   Moduledir   %ROOT%\modules
   CacheDir    %ROOT%\data
   Pidfile     %ROOT%\data\nxlog.pid
   SpoolDir    %ROOT%\data
   LogFile     %ROOT%\data\nxlog.log
   
   <Input in_adcontext>
       Module im_file
       File "<Path_of_the_output_file>"
       DirCheckInterval 3600
       PollInterval 3600
   </Input>
   
   <Output out_chronicle_adcontext>
       Module  om_tcp
       Host    %ADCONTEXT_OUTPUT_DESTINATION_ADDRESS%
       Port    %ADCONTEXT_OUTPUT_DESTINATION_PORT%
   </Output>
   
   <Route ad_context_to_chronicle>
       Path in_adcontext => out_chronicle_adcontext
   </Route>
   

3. 在每个系统中启动 NXLog 服务。

在中央服务器上配置转发器

如需了解如何在 Linux 上安装和配置转发器，请参阅在 Linux 上安装和配置转发器。 如需了解如何在 Microsoft Windows 上安装和配置转发器，请参阅在 Microsoft Windows 上安装和配置转发器。

1. 使用世界协调时间 (UTC) 时区配置系统。
2. 在中央 Microsoft Windows 或 Linux 服务器上安装 Google Security Operations 转发器。

3. 配置 Google Security Operations 转发器，以将日志发送到 Google Security Operations。 以下是转发器配置示例：

     - syslog:
         common:
           enabled: true
           data_type: WINDOWS_AD
           batch_n_seconds: 10
           batch_n_bytes: 1048576
         tcp_address: 0.0.0.0:10518
         connection_timeout_sec: 60
   

支持的 Windows AD 日志格式

Windows AD 解析器支持 JSON 格式的日志。
