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 loginpowerpipe 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 subscriptionfrom azure_eventhub_namespace as a left join eventhub_service_connection as c on c.id = a.id, azure_subscription as subwhere sub.subscription_id = a.subscription_id;
