Managed HSM should enable purge protection

Critical Azure General managedhsm-purge-protection

Applies to

Microsoft.KeyVault/managedHSMs

What CGPulse checks

A resource passes this rule when purgeProtection must equal true. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Enable purge protection to prevent permanent deletion before retention ends. In Azure Portal: Managed HSM > Properties > enable Purge protection. See: https://learn.microsoft.com/en-us/azure/key-vault/managed-hsm/soft-delete-overview

CLI

az keyvault update-hsm --ids "{id}" --enable-purge-protection true

Terraform

resource "azurerm_key_vault_managed_hardware_security_module" "{name}" {
  name                       = "{name}"
  resource_group_name        = "{rg}"
  location                   = var.location
  sku_name                   = "Standard_B1"
  tenant_id                  = data.azurerm_client_config.current.tenant_id
  admin_object_ids           = [data.azurerm_client_config.current.object_id]
  purge_protection_enabled   = true
  soft_delete_retention_days = 90
}
