The ESXi host must not be configured to override virtual machine (VM) logger settings.

Description
Each VM on an ESXi host runs in its own "vmx" process. Upon creation, a vmx process will look in two locations for configuration items, the ESXi host itself and the per-vm *.vmx file in the VM storage path on the datastore. The settings on the ESXi host are read first and take precedence over settings in the *.vmx file. This can be a convenient way to set a setting in one place and have it apply to all VMs running on that host. The difficulty is in managing those settings and determining the effective state. Since managing per-VM vmx settings can be fully automated and customized while the ESXi setting cannot be easily queried, the ESXi configuration must not be used.

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-258792r933437_chk)

From an ESXi shell, run the following command: # grep "^vmx\.log" /etc/vmware/config If the command produces any output, this is a finding.

Fix Text (F-62441r933436_fix)

From an ESXi shell, run the following commands: # cp /etc/vmware/config /etc/vmware/config.bak # grep -v "^vmx\.log" /etc/vmware/config.bak>/etc/vmware/config
