Configuring Cloud Scanner for Microsoft Azure

Cloud Scanner can be deployed using one of the following:

Azure Container Instance
Azure Kubernetes Cluster
Azure Virtual Machine

Cloud Scanner on Azure Container Instance

You need to configure Terraform with the appropriate resources and inputs for your particular scenario, and you will need to provide the IP address or DNS name for the ThreatMapper management console and an API key.

Copy and paste the following into a new file cloud-scanner.tf. Edit the fields: region, mgmt-console-url and deepfence-key.

Single Subscription

Monitor a single Azure subscription

provider "azurerm" {
  features {}
  # Subscription ID to deploy the Azure Container Service
  subscription_id = "<SUBSCRIPTION_ID eg. XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX>"
}

module "cloud-scanner_example_single-subscription" {
  source              = "deepfence/cloud-scanner/azure//examples/single-subscription"
  version             = "0.9.1"
  mgmt-console-url    = "<Console URL> eg. XXX.XXX.XX.XXX"
  mgmt-console-port   = "443"
  deepfence-key       = "<Deepfence-key> eg. XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
  name                = "deepfence-cloud-scanner"
  image               = "quay.io/deepfenceio/cloud_scanner_ce:2.5.2"
  # Location name https://gist.github.com/ausfestivus/04e55c7d80229069bf3bc75870630ec8#results
  location            = "eastus"
  # Number of CPU cores (Default: 2 vCPU)
  cpu                 = "2"
  # Memory in GB (Default: 4 GB)
  memory              = "4"
  tags = {
    product = "deepfence-cloud-scanner"
  }
}

Tenant subscriptions

Monitor multiple subscriptions in a Tenant

provider "azurerm" {
  features {}
  # Subscription ID to deploy the Azure Container Service
  subscription_id = "<SUBSCRIPTION_ID eg. XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX>"
}

module "cloud-scanner_example_tenant-subscriptions" {
  source                  = "deepfence/cloud-scanner/azure//examples/tenant-subscriptions"
  version                 = "0.9.1"
  mgmt-console-url        = "<Console URL> eg. XXX.XXX.XX.XXX"
  mgmt-console-port       = "<Console port> eg. 443"
  deepfence-key           = "<Deepfence-key> eg. XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
  name                    = "deepfence-cloud-scanner"
  image                   = "quay.io/deepfenceio/cloud_scanner_ce:2.5.2"
  # List of subscription ids to monitor
  subscription_ids_access = ["XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX", "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"]
  # Location name https://gist.github.com/ausfestivus/04e55c7d80229069bf3bc75870630ec8#results
  location                = "eastus"
  # Number of CPU cores (Default: 4 vCPU)
  cpu                     = "4"
  # Memory in GB (Default: 8 GB)
  memory                  = "8"
  tags = {
    product = "deepfence-cloud-scanner"
  }
}

Ensure that the name parameter is set to some unique string to avoid collision with existing resource names in the subscription

Then run

terraform init
terraform plan
terraform apply

Cloud Scanner on Azure virtual machine

info

Pre-requisite:

Install docker and docker compose on the Azure virtual machine (refer docker documentation for installation instructions)
If an existing Azure virtual machine is used, check if docker and docker compose plugins are installed on the Azure virtual machine.
azure cli is configured and is able to access the required project where cloud scanner will be deployed

Copy and paste the following (single tenant or multiple tenant) into a new file cloud-scanner.tf. Edit the fields: SUBSCRIPTION_ID and subscription_ids_access if required.

Single Subscription Cloud Scanner on Azure virtual machine

provider "azurerm" {
  subscription_id = "<SUBSCRIPTION_ID>"
  features {}
}

data "azurerm_subscription" "current" {}

module "infrastructure_cloud-scanner-app" {
  source                  = "deepfence/cloud-scanner/azure//modules/infrastructure/cloud-scanner-app"
  version                 = "0.9.1"
  name                    = "deepfence-cloud-scanner"
  subscription_ids_access = [data.azurerm_subscription.current.subscription_id]
}

output "tenant_id" {
  value = module.infrastructure_cloud-scanner-app.tenant_id
}

output "client_id" {
  value = module.infrastructure_cloud-scanner-app.client_id
}

output "client_secret" {
  value     = module.infrastructure_cloud-scanner-app.client_secret
  sensitive = true
}

Apply the terraform script and note the output tenant_id, client_id and client_secret. Please run this command to retrieve client_secret from terraform output.
```
terraform output client_secret
```

Create a directory deepfence-cloud-scanner and download docker-compose.yaml from the url

What Compliance Scans are Performed?

ThreatMapper builds on a large library of controls - these are specific requirements and matching tests. For example, you will find controls that correspond to best-practice configurations of access to assets, such as enabling TLS access and blocking plain-text HTTP.

Controls are grouped into benchmarks. Where multiple benchmarks are available, controls may be used by several benchmarks.

When you run a compliance scan, you can select which benchmarks you wish to measure against, and ThreatMapper will then evaluate the appropriate controls and present the results, by benchmark, once the scan has completed.

For full information, refer to Operations: Compliance Scanning.

Maximizing Coverage

For maximum coverage, you can use both Cloud Scanner and local Sensor Agent compliance scans together. You could scan your Azure infrastructure using Cloud Scanner, and scan selected VMs deployed within Azure using the Sensor Agent.
