Description
The MOB provides a way to explore the object model used by the VMkernel to manage the host and enables configurations to be changed. This interface is meant to be used primarily for debugging the vSphere Software Development Kit (SDK), but because there are no access controls it could also be used as a method to obtain information about a host being targeted for unauthorized access.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-256399r958478_chk)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "Config.HostAgent.plugins.solo.enableMob" value and verify it is set to "false". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name Config.HostAgent.plugins.solo.enableMob If the "Config.HostAgent.plugins.solo.enableMob" setting is not set to "false", this is a finding.
