Control: The default stateless action for Network Firewall policies should be drop or forward for full packets

Description

A firewall policy defines how your firewall monitors and handles traffic in AWS VPC. You configure stateless and stateful rule groups to filter packets and traffic flows. Defaulting to Pass can allow unintended traffic.

Usage

Run the control in your terminal:

powerpipe control run aws_compliance.control.networkfirewall_firewall_policy_default_stateless_action_check_full_packets

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run aws_compliance.control.networkfirewall_firewall_policy_default_stateless_action_check_full_packets --share

SQL

This control uses a named query:

select
  arn as resource,
  case
    when (not (firewall_policy -> 'StatelessDefaultActions') ? 'aws:drop'
        and not (firewall_policy -> 'StatelessDefaultActions') ? 'aws:forward_to_sfe') then 'alarm'
    else 'ok'
  end as status,
  case
    when (not (firewall_policy -> 'StatelessDefaultActions') ? 'aws:drop'
      and not (firewall_policy -> 'StatelessDefaultActions') ? 'aws:forward_to_sfe') then title || ' stateless action is neither drop nor forward for full packets.'
    else title || ' stateless action is either drop or forward for full packets.'
  end as reason
  
  , region, account_id
