Cognitive Services should use Managed Identity

Applies to

• Microsoft.CognitiveServices/accounts

What CGPulse checks

A resource passes this rule when identity.type must be set. 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: Cognitive Services > Identity > enable System-assigned managed identity. See: https://learn.microsoft.com/en-us/azure/ai-services/disable-local-auth

CLI

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

Terraform

resource "azurerm_cognitive_account" "{name}" {
  name                = "{name}"
  resource_group_name = "{rg}"
  location            = var.location
  kind                = "CognitiveServices"
  sku_name            = "S0"
  identity {
    type = "SystemAssigned"
  }
}
