The vCenter Server for Windows must restrict access to cryptographic permissions.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-94831	VCWN-65-000064	SV-104661r1_rule		Medium

Description
These permissions must be reserved for cryptographic administrators where VM encryption and/or vSAN encryption is in use. Catastrophic data loss can result from a poorly administered cryptography.

From the vSphere Web Client go to Administration >> Access Control >> Roles Highlight each role and click the pencil button if it is enabled. Verify that only the "Administrator" and any site-specific cryptographic group(s) have the following permissions: Cryptographic Operations privileges Global.Diagnostics Host.Inventory.Add host to cluster Host.Inventory.Add standalone host Host.Local operations.Manage user groups or From a PowerCLI command prompt while connected to the vCenter server run the following command: $roles = Get-VIRole ForEach($role in $roles){ $privileges = $role.PrivilegeList If($privileges -match "Crypto" -or $privileges -match "Global.Diagnostics" -or $privileges -match "Host.Inventory.Add" -or $privileges -match "Host.Local operations.Manage user groups"){ Write-Host "$role has Cryptographic privileges" } } If any role other than "Administrator" or any site-specific group(s) have any of these permissions, this is a finding.

From the vSphere Web Client go to Administration >> Access Control >> Roles

Highlight each role and click the pencil button if it is enabled. Verify that only the "Administrator" and any site-specific cryptographic group(s) have the following permissions:

Cryptographic Operations privileges
Global.Diagnostics
Host.Inventory.Add host to cluster
Host.Inventory.Add standalone host
Host.Local operations.Manage user groups

or

From a PowerCLI command prompt while connected to the vCenter server run the following command:
$roles = Get-VIRole
ForEach($role in $roles){
$privileges = $role.PrivilegeList
If($privileges -match "Crypto*" -or $privileges -match "Global.Diagnostics" -or $privileges -match "Host.Inventory.Add*" -or $privileges -match "Host.Local operations.Manage user groups"){
Write-Host "$role has Cryptographic privileges"
}
}

If any role other than "Administrator" or any site-specific group(s) have any of these permissions, this is a finding.
