Control: Event Hub namespaces should use private link

Description

Azure Private Link lets you connect your virtual network to Azure services without a public IP address at the source or destination. The Private Link platform handles the connectivity between the consumer and services over the Azure backbone network. By mapping private endpoints to Event Hub namespaces, data leakage risks are reduced.

Usage

Run the control in your terminal:

powerpipe control run azure_compliance.control.eventhub_namespace_private_link_used

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run azure_compliance.control.eventhub_namespace_private_link_used --share

SQL

This control uses a named query:

with eventhub_service_connection as (
select
distinct a.id
from
azure_eventhub_namespace as a,
jsonb_array_elements(private_endpoint_connections) as connection
where
connection -> 'privateLinkServiceConnectionState' ->> 'status' = 'Approved'
)
select
a.id as resource,
case
when sku_tier = 'Basic' then 'skip'
when c.id is null then 'alarm'
else 'ok'
end as status,
case
when sku_tier = 'Basic' then a.name || ' is of ' || sku_tier || ' tier.'
when c.id is null then a.name || ' not uses private link.'
else a.name || ' uses private link.'
end as reason,
a.resource_group as resource_group,
sub.display_name as subscription
from
azure_eventhub_namespace as a
left join eventhub_service_connection as c on c.id = a.id,
azure_subscription as sub
where
sub.subscription_id = a.subscription_id;
