Carbon Black Cloud: How To Check DeviceID On Endpoint (Windows, 3.7+)

[#1]

Environment

• Carbon Black Cloud Sensor: 3.7.x.x and Higher
• Microsoft Windows: All Supported Versions

Objective

Explain the steps to confirm the DeviceID of a 3.7.x.x or higher Sensor on the machine where it is installed

Resolution

CMD.EXE

1. Launch an elevated command prompt (right-click cmd.exe > Run as Administrator)
2. Run the following command

   findstr "RegistrationId" C:\ProgramData\CarbonBlack\DataFiles\cfg.ini

3. The output will be in the following format

   RegistrationId=<org_id>-<device_id>

Powershell

1. Launch an elevated Powershell.exe instance (right-click powershell.exe > Run as Administrator)
2. Run the following command

   Select-String "RegistrationId" C:\ProgramData\CarbonBlack\DataFiles\cfg.ini

3. The output will be in the following format

   C:\ProgramData\CarbonBlack\DataFiles\cfg.ini:<Line#>:RegistrationId=<org_id>-<device_id>

Additional Notes

• Confirming the DeviceID locally on the machine with the Sensor installed can be helpful in troubleshooting issues and reviewing Alerts and other Events within the Carbon Black Cloud Console
• For example, with the DeviceID you can review Events specific to that single device on the Investigate page by replacing <DeviceID> with the ID retrieved using the above method

  https://<DashboardURL>/investigate?selected[deviceId]=<DeviceID>&selected[selectedTab]=DEVICE&s[searchWindow]=ALL&s[c][DEVICE_ID][0]=<DeviceID>

• Searching for device_id on applicable Inventory pages will find the device tied to that registration, regardless of the current hostname
  • device_id is the unique identifier for a given Sensor in relation to VMware Carbon Black Cloud
  • Hostname, IP Address, and Active Directory information are all considered metadata for a device record as they all can be changed
• Point of presence (PoP) or Backend can also be found in the cfg.ini file to ensure a given device is registered to the correct PoP/Backend

  cmd.exe
  \> findstr "BackendServer" C:\ProgramData\CarbonBlack\DataFiles\cfg.ini
  BackendServer=<Device_Services_URL>
  
  Powershell.exe
  \> Select-String "BackendServer" C:\ProgramData\CarbonBlack\DataFiles\cfg.ini
  C:\ProgramData\CarbonBlack\DataFiles\cfg.ini:<Line#>:BackendServer=<Device_Services_URL>
