Storage account must enforce HTTPS transfer

High Azure General storage-https-only

Applies to

Microsoft.Storage/storageAccounts

What CGPulse checks

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

How to fix it

Enable HTTPS-only transfer to encrypt all data in transit. In Azure Portal: Storage account > Configuration > set Secure transfer required to Enabled. See: https://learn.microsoft.com/en-us/azure/storage/common/storage-require-secure-transfer

CLI

az storage account update --ids "{id}" --https-only true

Terraform

resource "azurerm_storage_account" "{name}" {
  name                      = "{name}"
  resource_group_name       = "{rg}"
  location                  = var.location
  account_tier              = "Standard"
  account_replication_type  = "LRS"
  https_traffic_only_enabled = true
}
