The vCenter Server must restrict access to cryptographic permissions.

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

By default, there are five roles that contain cryptographic related permissions: Administrator, No Trusted Infrastructure Administrator, vCLSAdmin, VMOperator Controller Manager, and vSphere Kubernetes Manager.

From the vSphere Client, go to Administration >> Access Control >> Roles.

Highlight each role and click the "Privileges" button in the right pane.

Verify that only the Administrator, No Trusted Infrastructure Administrator, vCLSAdmin, and vSphere Kubernetes Manager and any site-specific cryptographic roles 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 commands:

$roles = Get-VIRole ForEach($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 the five default roles contain the permissions listed above and is not authorized to perform cryptographic related operations, this is a finding.

From the vSphere Client, go to Administration >> Access Control >> Roles.

Highlight the target custom role and click "Edit".

Remove the following permissions from any custom role that is not authorized to perform cryptographic related operations:

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