Control: 2.1.18 Ensure That 'All users with the following roles' is set to 'Owner'

Description

Select Microsoft Defender for Cloud.
Click on Environment Settings.
Click on the appropriate Management Group, Subscription, or Workspace.

Click Save.

az account get-access-token --query

https://management.azure.com/subscriptions/$0/providers/Microsoft.Security/se curityContacts/default1?api-version=2017-08-01-preview -d@"input.json"'

with contact_info as (
  select
    count(*) filter (where alerts_to_admins = 'On') as admin_alert_count,
    subscription_id
  from
    azure_security_center_contact
  group by
    subscription_id
  limit 1
)
select
  sub.subscription_id as resource,
  case
    when admin_alert_count > 0 then 'ok'
    else 'alarm'
  end as status,
  case
    when admin_alert_count > 0 then '"All users with the following roles" set to Owner'
    else '"All users with the following roles" not set to Owner.'
  end as reason
  
  , sub.display_name as subscription
from
  azure_subscription sub
  left join contact_info ci on sub.subscription_id = ci.subscription_id;
