Key Vault should disable public network access

High Azure General keyvault-no-public-access-2

Applies to

Microsoft.KeyVault/vaults

What CGPulse checks

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

How to fix it

Disable public network access to prevent unauthorized internet exposure. In Azure Portal: Key Vault > Networking > set Public network access to Disabled. See: https://learn.microsoft.com/en-us/azure/key-vault/general/network-security

Careful: Disabling public access blocks ALL connections not using private endpoints

CLI

az keyvault update --ids "{id}" --public-network-access Disabled

Terraform

resource "azurerm_key_vault" "{name}" {
  name                          = "{name}"
  resource_group_name           = "{rg}"
  location                      = var.location
  tenant_id                     = data.azurerm_client_config.current.tenant_id
  sku_name                      = "standard"
  public_network_access_enabled = false
}
