TMA-ESXI9-7.2
Virtual machines must require encryption for vMotion
Descrição
Requiring encryption for vMotion ensures the secure transfer of data among virtual machines. While the default 'opportunistic' encryption setting generally provides encryption due to prevalent AES-NI support, enforcing 'required' encryption eradicates the possibility of unencrypted transfers. Expected: migrate.encryptionMode = "required". The audit parses every .vmx file under /vmfs/volumes/ on the host and lists the VMs that do not comply; it passes when none are found (or no VMs exist). Runs in the ESXi Shell (busybox sh) as root.

Como é corrigido
Método de correção: Orientação ou patch de infraestrutura
The following PowerCLI command may be used: $VMview = Get-VM -Name $VM | Get-View $ConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $ConfigSpec.MigrateEncryption = New-Object VMware.Vim.VirtualMachineConfigSpecEncryptedVMotionModes $ConfigSpec.MigrateEncryption = "required" $VMview.ReconfigVM_Task($ConfigSpec)
