Recovery Services vault should disable public network access

Medium Azure General recovery-vault-no-public-access

Applies to

Microsoft.RecoveryServices/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: Recovery Services vault > Networking > set Public network access to Disabled. See: https://learn.microsoft.com/en-us/azure/backup/private-endpoints

Careful: Disabling public access blocks backup agents not using private endpoints. Ensure MARS/MABS agents connect via private endpoints

CLI

az resource update --ids "{id}" --set properties.publicNetworkAccess=Disabled

Terraform

resource "azurerm_recovery_services_vault" "{name}" {
  name                         = "{name}"
  resource_group_name          = "{rg}"
  location                     = var.location
  sku                          = "Standard"
  public_network_access_enabled = false
}
