Automation Account should disable public network access

High Azure General automation-no-public-access

Applies to

Microsoft.Automation/automationAccounts

What CGPulse checks

A resource passes this rule when publicNetworkAccess must equal false. 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: Automation Account > Networking > set Public network access to Disabled. See: https://learn.microsoft.com/en-us/azure/automation/how-to/private-link-security

Careful: Disabling public access blocks all non-private-endpoint traffic including hybrid worker communication. Ensure private endpoints are configured first

CLI

az automation account update --ids "{id}" --set properties.publicNetworkAccess=false

Terraform

resource "azurerm_automation_account" "{name}" {
  name                          = "{name}"
  resource_group_name           = "{rg}"
  location                      = var.location
  sku_name                      = "Basic"
  public_network_access_enabled = false
}
