Firewall Policy should use Premium SKU tier

Medium Azure General firewallpolicies-firewall-policy-premium-sku

Applies to

Microsoft.Network/firewallPolicies

What CGPulse checks

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

How to fix it

Upgrade to Premium tier for TLS inspection, IDPS, URL filtering, and web categories. In Azure Portal: Firewall Policy > Overview > change tier to Premium. See: https://learn.microsoft.com/en-us/azure/firewall/premium-features

CLI

az network firewall policy update --ids "{id}" --sku Premium

Terraform

resource "azurerm_firewall_policy" "{name}" {
  name                = "{name}"
  resource_group_name = "{rg}"
  location            = var.location
  sku                 = "Premium"
}
