Communication Service should use managed identity

Medium Azure General communicationservices-managed-identity

Applies to

Microsoft.Communication/communicationServices

What CGPulse checks

A resource passes this rule when identity.type must be one of ["SystemAssigned","UserAssigned","SystemAssigned,UserAssigned"]. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Enable managed identity to eliminate stored credentials and improve security. In Azure Portal: Communication Services > Identity > enable System-assigned managed identity. See: https://learn.microsoft.com/en-us/azure/communication-services/concepts/identity-model

CLI

az resource update --ids "{id}" --set identity.type=SystemAssigned

Terraform

resource "azurerm_communication_service" "{name}" {
  name                = "{name}"
  resource_group_name = "{rg}"
  data_location       = "Europe"

  identity {
    type = "SystemAssigned"
  }
}
