The ESXi Image Profile and vSphere Installation Bundle (VIB) acceptance levels must be verified.

Description
Verify the ESXi Image Profile to only allow signed VIBs. An unsigned VIB represents untested code installed on an ESXi host. The ESXi Image profile supports four acceptance levels: 1. VMwareCertified - VIBs created, tested, and signed by VMware. 2. VMwareAccepted - VIBs created by a VMware partner but tested and signed by VMware. 3. PartnerSupported - VIBs created, tested, and signed by a certified VMware partner. 4. CommunitySupported - VIBs that have not been tested by VMware or a VMware partner. Community Supported VIBs are not supported and do not have a digital signature. To protect the security and integrity of ESXi hosts, do not allow unsigned (CommunitySupported) VIBs to be installed on hosts. Satisfies: SRG-OS-000366-VMM-001430, SRG-OS-000370-VMM-001460, SRG-OS-000404-VMM-001650

Who does this work

8 NICE work roles and 8 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-256410r984242_chk)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Security Profile. Under "Host Image Profile Acceptance Level", view the acceptance level. or From a PowerCLI command prompt while connected to the ESXi host, run the following commands: $esxcli = Get-EsxCli -v2 $esxcli.software.acceptance.get.Invoke() If the acceptance level is "CommunitySupported", this is a finding.

Fix Text (F-60028r892863_fix)

From the vSphere Client, select the ESXi Host and go to Configure >> System >> Security Profile. Under "Host Image Profile Acceptance Level", click "Edit...". Using the drop-down selection, set the acceptance level as "VMwareCertified", "VMwareAccepted", or "PartnerSupported". The default is "PartnerSupported". or From a PowerCLI command prompt while connected to the ESXi host, run the following commands: $esxcli = Get-EsxCli -v2 $arguments = $esxcli.software.acceptance.set.CreateArgs() $arguments.level = "PartnerSupported" $esxcli.software.acceptance.set.Invoke($arguments) Note: "VMwareCertified" or "VMwareAccepted" may be substituted for "PartnerSupported", depending on local requirements. These are case sensitive.
