Control: Containerized applications should use security services such as SELinux or AppArmor or Seccomp

Description

The underlying host OS needs to be secured in order to prevent container breaches from affecting the host. For this, Linux provides several out-of-the-box security modules. Some of the popular ones are SELinux, AppArmor and Seccomp.

Usage

Run the control in your terminal:

powerpipe control run kubernetes_compliance.control.pod_security_policy_security_services_hardening

Snapshot and share results via Turbot Pipes:

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

SQL

This control uses a named query:

select
  coalesce(uid, concat(path, ':', start_line)) as resource,
  case
    when se_linux -> 'rule' = '"MustRunAs"' then 'ok'
    when annotations -> 'apparmor.security.beta.kubernetes.io/defaultProfileName' = '"runtime/default"' then 'ok'
    when annotations -> 'seccomp.security.alpha.kubernetes.io/defaultProfileName' = '"runtime/default"' then 'ok'
    else 'alarm'
  end as status,
  case
    when se_linux -> 'rule' = '"MustRunAs"' then 'Applications using SELinux security service.'
    when annotations -> 'apparmor.security.beta.kubernetes.io/defaultProfileName' = '"runtime/default"' then 'Pod security policy ' || name || ' using AppArmor security service.'
    when annotations -> 'seccomp.security.alpha.kubernetes.io/defaultProfileName' = '"runtime/default"' then 'Pod security policy ' || name || ' using Seccomp security service.'
    else 'Pod security policy ' || name || ' not using securty services.'
  end as reason
  
  , coalesce(context_name, '') as context_name, source_type, coalesce(path || ':' || start_line || '-' || end_line, '') as path
