Control: Pod Security Policy should prohibit host network access

Description

Pod Security Policy host network controls whether the Pod may use the node network namespace. Doing so gives the Pod access to the loopback device, services listening on localhost, and could be used to snoop on network activity of other Pods on the same node.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.pod_security_policy_host_network_access_disabled

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run kubernetes_compliance.control.pod_security_policy_host_network_access_disabled --share

SQL

This control uses a named query:

select
  coalesce(uid, concat(path, ':', start_line)) as resource,
  case
    when host_network then 'alarm'
    else 'ok'
  end as status,
  case
    when host_network then 'Pod security policy ' || name || ' pods can use the host network.'
    else 'Pod security policy ' || name || ' pods cannot use the host network.'
  end as reason
  
  , coalesce(context_name, '') as context_name, source_type, coalesce(path || ':' || start_line || '-' || end_line, '') as path
from
  kubernetes_pod_security_policy;
