To properly set the owner of /etc/cron.hourly, run the command:

$ sudo chown root /etc/cron.hourly 


Service configuration files enable or disable features of their respective services that if configured incorrectly can lead to insecure and vulnerable configurations. Therefore, service configuration files should be owned by the correct user to prevent unauthorized changes.


Shell script

The following script can be run on the host to remediate the issue.


# Remediation is applicable only in certain platforms
if [ ! -f /.dockerenv ] && [ ! -f /run/.containerenv ]; then

find -H /etc/cron.hourly/ -maxdepth 1 -type d -exec chown 0 {} \;

    >&2 echo 'Remediation is not applicable, nothing was done'

Ansible playbook

The following playbook can be run with Ansible to remediate the issue.

- name: Ensure owner on directory /etc/cron.hourly/
    path: /etc/cron.hourly/
    state: directory
    owner: '0'
  when: ansible_virtualization_type not in ["docker", "lxc", "openvz", "podman", "container"]
