收集 Cisco ISE 日志

支持的平台：

Google SecOps SIEM

注意： 此功能受《Google Security Operations 服务专用条款》的正式发布前产品条款的约束。我们对正式发布前功能的支持可能有限，并且对正式发布前功能的更改与其他正式发布前版本可能不兼容。如需了解详情，请参阅 Google SecOps 技术支持服务准则和 Google SecOps 服务专用条款。

本文档介绍了如何使用 Bindplane 将 Cisco ISE 日志注入到 Google Security Operations。

解析器从 Cisco ISE syslog 和 CSV 格式的日志中提取字段。它使用 grok 和/或 kv 来解析日志消息，然后将这些值映射到统一数据模型 (UDM)。它还会为事件来源和类型设置默认元数据值。

准备工作

请确保满足以下前提条件：

• Google SecOps 实例
• Windows Server 2016 或更高版本，或者具有 systemd 的 Linux 主机
• 如果通过代理运行，请确保防火墙端口已根据 Bindplane 代理要求打开
• 对 Cisco ISE 管理门户的特权访问权限

获取 Google SecOps 注入身份验证文件

1. 登录 Google SecOps 控制台。
2. 依次前往 SIEM 设置 > 收集代理。
3. 下载注入身份验证文件。将文件安全地保存在将要安装 Bindplane 的系统上。

注意： 此 JSON 文件包含用于向 Google SecOps 验证 Bindplane 代理身份的凭据。

获取 Google SecOps 客户 ID

1. 登录 Google SecOps 控制台。
2. 依次前往 SIEM 设置 > 配置文件。
3. 复制并保存组织详细信息部分中的客户 ID。

注意： 配置 Bindplane 代理导出器需要客户 ID。

安装 Bindplane 代理

按照以下说明在 Windows 或 Linux 操作系统上安装 Bindplane 代理。

Windows 安装

1. 以管理员身份打开命令提示符或 PowerShell。

2. 运行以下命令：

   msiexec /i "https://github.com/observIQ/bindplane-agent/releases/latest/download/observiq-otel-collector.msi" /quiet
   

3. 等待安装完成。

4. 运行以下命令来验证安装：

   sc query observiq-otel-collector
   

该服务应显示为 RUNNING。

Linux 安装

1. 打开具有 root 或 sudo 权限的终端。

2. 运行以下命令：

   sudo sh -c "$(curl -fsSlL https://github.com/observiq/bindplane-agent/releases/latest/download/install_unix.sh)" install_unix.sh
   

3. 等待安装完成。

4. 运行以下命令来验证安装：

   sudo systemctl status observiq-otel-collector
   

该服务应显示为有效（正在运行）。

其他安装资源

如需了解其他安装选项和问题排查信息，请参阅 Bindplane 代理安装指南。

配置 Bindplane 代理以注入 syslog 并将其发送到 Google SecOps

找到配置文件

• Linux：

  sudo nano /etc/bindplane-agent/config.yaml
  

• Windows：

  notepad "C:\Program Files\observIQ OpenTelemetry Collector\config.yaml"
  

修改配置文件

• 将 config.yaml 的全部内容替换为以下配置：

  receivers:
      udplog:
          listen_address: "0.0.0.0:514"
  
  exporters:
      chronicle/chronicle_w_labels:
          compression: gzip
          creds_file_path: '/path/to/ingestion-authentication-file.json'
          customer_id: 'YOUR_CUSTOMER_ID'
          endpoint: malachiteingestion-pa.googleapis.com
          log_type: 'CISCO_ISE'
          raw_log_field: body
          ingestion_labels:
  
  service:
      pipelines:
          logs/source0__chronicle_w_labels-0:
              receivers:
                  - udplog
              exporters:
                  - chronicle/chronicle_w_labels
  

配置参数

• 替换以下占位符：

  • 接收器配置：

    • udplog：使用 udplog 表示 UDP syslog，使用 tcplog 表示 TCP syslog
    • 0.0.0.0：要监听的 IP 地址（0.0.0.0 表示监听所有接口）
    • 514：要监听的端口号（标准 syslog 端口）

  • 导出器配置：

    • creds_file_path：提取身份验证文件的完整路径：
      • Linux：/etc/bindplane-agent/ingestion-auth.json
      • Windows：C:\Program Files\observIQ OpenTelemetry Collector\ingestion-auth.json
    • YOUR_CUSTOMER_ID：从“获取客户 ID”部分获取的客户 ID
    • endpoint：区域端点网址：
      • 美国：malachiteingestion-pa.googleapis.com
      • 欧洲：europe-malachiteingestion-pa.googleapis.com
      • 亚洲：asia-southeast1-malachiteingestion-pa.googleapis.com
      • 如需查看完整列表，请参阅区域级端点
    • log_type：日志类型，与在 Chronicle 中显示的完全一致 (CISCO_ISE)

保存配置文件

• 修改后，保存文件：
  • Linux：依次按 Ctrl+O、Enter 和 Ctrl+X
  • Windows：依次点击文件 > 保存

重启 Bindplane 代理以应用更改

• 如需在 Linux 中重启 Bindplane 代理，请运行以下命令：

  sudo systemctl restart observiq-otel-collector
  

  1. 验证服务是否正在运行：

       sudo systemctl status observiq-otel-collector
     

  2. 检查日志是否存在错误：

       sudo journalctl -u observiq-otel-collector -f
     

• 如需在 Windows 中重启 Bindplane 代理，请选择以下选项之一：

  • 以管理员身份运行命令提示符或 PowerShell：

    net stop observiq-otel-collector && net start observiq-otel-collector
    

  • 服务控制台：

    1. 按 Win+R，输入 services.msc，然后按 Enter 键。
    2. 找到 observIQ OpenTelemetry 收集器。

    3. 右键点击并选择重新启动。

    4. 验证服务是否正在运行：

       sc query observiq-otel-collector
       

    5. 检查日志是否存在错误：

       type "C:\Program Files\observIQ OpenTelemetry Collector\log\collector.log"
       

在 Cisco ISE 上配置 Syslog 转发

1. 登录 Cisco ISE 管理门户。
2. 依次前往管理 > 系统 > 日志记录 > 远程日志记录目标。
3. 点击添加以创建新的远程日志记录目标。
4. 提供以下配置详细信息：
   • 名称：输入一个描述性名称（例如 Google-SecOps-Bindplane）。
   • 说明：输入说明（可选）。

   • 端口：输入 514。
   • 设备代码：选择 LOCAL6（或您偏好的设备）。
   • 最大长度：输入 8192（或支持的最大值）。
   • 在 Syslog 消息中包含闹钟：选中此复选框可包含闹钟。
5. 点击保存。
6. 依次前往管理 > 系统 > 日志记录 > 日志记录类别。
7. 选择要转发的每个日志记录类别，然后点击修改：
   • AAA 审核
   • AAA 诊断
   • 会计
   • 管理员审核
   • 安全状况和客户端配置审核
   • Profiler
   • 系统诊断
8. 在目标部分中，将远程日志记录目标 Google-SecOps-Bindplane 从可用移至已选择。
