Control: 2.1.6 Ensure That Microsoft Defender for Azure Cosmos DB Is Set To 'On'

Description

Microsoft Defender for Azure Cosmos DB scans all incoming network requests for threats to your Azure Cosmos DB resources.

In scanning Azure Cosmos DB requests within a subscription, requests are compared to a heuristic list of potential security threats. These threats could be a result of a security breach within your services, thus scanning for them could prevent a potential security threat from being introduced.

Remediation

From Azure Portal

Go to Microsoft Defender for Cloud.
Select Environment Settings blade.
Click on the subscription name.
Select the Defender plans blade.
On the Database row click on Select types >.
Set the radio button next to Azure Cosmos DB to On.
Click Continue.
Click Save.

From Azure CLI

Run the following command:

az security pricing create -n 'CosmosDbs' --tier 'standard'

From Powershell

Use the below command to enable Standard pricing tier for Azure Cosmos DB

Set-AzSecurityPricing -Name 'CosmosDbs' -PricingTier 'Standard

Default Value

By default, Microsoft Defender for Azure Cosmos DB is not enabled.

Usage

Run the control in your terminal:

powerpipe control run azure_compliance.control.cis_v210_2_1_6

Snapshot and share results via Turbot Pipes:

SQL

This control uses a named query:

select
  sub_pricing.id as resource,
  case
    when pricing_tier = 'Standard' then 'ok'
    else 'alarm'
  end as status,
  case
    when pricing_tier = 'Standard' then 'Azure Defender on for Cosmos DB.'
    else 'Azure Defender off for Cosmos DB.'
  end as reason
  
  , sub.display_name as subscription
from
  azure_security_center_subscription_pricing sub_pricing
  right join azure_subscription sub on sub_pricing.subscription_id = sub.subscription_id
where
  name = 'CosmosDbs';
