Control: Minimize the admission of containers wishing to share the host IPC namespace

Description

A container running in the host's IPC namespace can use IPC to interact with processes outside the container. There should be at least one PodSecurityPolicy (PSP) defined which does not permit containers to share the host IPC namespace.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.pod_security_policy_hostipc_sharing_disabled

Snapshot and share results via Turbot Pipes:

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

SQL

This control uses a named query:

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