Description

Implement Firewall Premium features, as this has high security impact and would allow to free up more websites, as there is the option to do URL filtering, i.e. you can restrict on entire URLs. Details here: https://docs.microsoft.com/en-us/azure/firewall/premium-features

New or Affected Resource(s)

• azurerm_firewall_policy
• (azurerm_firewall) # if you would implement azurerm_firewall_policy as sub resource of azurerm_firewall

Potential Terraform Configuration

resource "azurerm_firewall_policy" "example" {
    name                = "example"
    resource_group_name = "example"
    location            = "West Europe"
    sku                   = "Premium"
    dns = {
     servers = ...
     proxy_enabled = ...
    }
   threat_intelligence_mode = "Deny"
   threat_intelligence_allow_list = {
     ip_addresses = [172.0.2.1]
     fqdns = ["www.google.com"]
   }
   intrusion_detection = {
     mode = "off" # "Alert", "Deny"
     configuration = {
       signature_overrides = {
         state = "off" # "Alert", "Deny"
         id = signature_id
         }
       bypass_traffic_settings = {
         name = "bypass_traffic_setting_1"
         description = ""
         protocol = "TCP"
         source_addresses = "*"
         destination_addresses = "*"
         destination_ports = "*"
         source_ip_groups = "*"
         destination_ip_groups = "*"
         }
       }
     }
  transport_security = {
    certificate_authority = {
      key_vault_secret_id = "..." // KeyVaultSecretID - Secret Id of (base-64 encoded unencrypted pfx) 'Secret' or 'Certificate' object stored in KeyVault.
      name = "..." // Name - Name of the CA certificate.
    }
  }
}

The intrusion_detection and transport_security blocks would be the new additions to the azurerm_firewall_policy resource. Alternatively, one could also integrate the azurerm_firewall_policy as a sub resource into the azurerm_firewall.
