CIS-Discovery Exam Dumps : Certified Implementation Specialist - Discovery

For ServiceNow Discovery to detect a Windows device, the Windows Management Instrumentation (WMI) service needs to be running on the host. WMI is a Windows feature that provides a standardized way to access management information about operating system components and services. Discovery uses WMI to query Windows hosts for information about their hardware, software, and system configuration. SSH is used for Unix-like systems, WinRM is an alternative Windows management protocol, and CIM (Common Information Model) is a cross-platform standard; however, WMI is the primary service used for Windows device discovery.

The MID Server parameters like 'mid.ssh.session_timeout', 'url', and 'mid.windows.management_protocol' can be modified through the ServiceNow platform UI under the MID Server configuration settings. These parameters control various aspects of the MID Server's operation, such as timeout settings for SSH sessions, the URL for the MID Server to communicate with the ServiceNow instance, and the management protocol to use for Windows servers, respectively. The 'name' of the MID Server, however, is not typically a parameter that can be changed through the UI as it is a unique identifier for the MID Server within the ServiceNow instance. Once a MID Server is registered with a name, that name is usually persistent and not intended to be modified through configuration settings.

File-based Discovery is a process that helps identify what software is running on your Windows and UNIX servers and devices, even if there is no registration information available. File-based Discovery is triggered in the exploration phase of normal Discovery, after the target device has been classified and identified. File-based Discovery probes execute a scan searching for specific file extensions or file names in paths that you configure. The resulting file information is returned in the probe payload. The sensor attempts to match the discovered files with installed software, using the file name, size, and version returned by the probe.
