Control: Storage accounts should restrict network access

Description

Network access to storage accounts should be restricted. Configure network rules so only applications from allowed networks can access the storage account. To allow connections from specific internet or on-premises clients, access can be granted to traffic from specific Azure virtual networks or to public internet IP address ranges.

Usage

Run the control in your terminal:

powerpipe control run terraform_azure_compliance.control.storage_account_default_network_access_rule_denied

Snapshot and share results via Turbot Pipes:

powerpipe control run terraform_azure_compliance.control.storage_account_default_network_access_rule_denied --share

SQL

This control uses a named query:

select
  address as resource,
  case
    when (attributes_std -> 'network_rules') is null then 'alarm'
    when (attributes_std -> 'network_rules' ->> 'default_action') = 'Allow' then 'alarm'
    else 'ok'
  end status,
  split_part(address, '.', 2) || case
    when (attributes_std -> 'network_rules') is null then ' has no network rules defined'
    when (attributes_std -> 'network_rules' ->> 'default_action') = 'Allow' then ' allows traffic from specific networks'
    else ' allows network access'
  end || '.' reason
  
  , path || ':' || start_line
from
  terraform_resource
where
