The ESXi Common Information Model (CIM) service must be disabled.

Description
The CIM system provides an interface that enables hardware-level management from remote applications via a set of standard application programming interfaces (APIs). These APIs are consumed by external applications such as HP SIM or Dell OpenManage for agentless, remote hardware monitoring of the ESXi host. To reduce attack surface area and following the minimum functionality principal, the CIM service must be disabled unless explicitly needed and approved.

Who does this work

10 NICE work roles and 9 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-258783r933410_chk)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Services. Under "Services", locate the "CIM Server" service and verify it is "Stopped" and the "Startup Policy" is set to "Start and stop manually". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-VMHostService | Where {$_.Label -eq "CIM Server"} If the "CIM Server" service does not have a "Policy" of "off" or is running, this is a finding.

Fix Text (F-62432r933409_fix)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Services. Under "Services" select the "CIM Server" service and click the "Stop" button. Click "Edit Startup policy..." and select the "Start and stop manually" radio button. Click "OK". or From a PowerCLI command prompt while connected to the ESXi host, run the following commands: Get-VMHost | Get-VMHostService | Where {$_.Label -eq "CIM Server"} | Set-VMHostService -Policy Off Get-VMHost | Get-VMHostService | Where {$_.Label -eq "CIM Server"} | Stop-VMHostService
