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

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-60028r886010_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.
