Ensure access to /etc/cron.hourly is configured

MediaNivel 1Automatizadalinux

Descripción

This directory contains system cron jobs that need to run on an hourly basis. The files in this directory cannot be manipulated by the crontab command, but are instead edited by system administrators using a text editor. The commands below restrict read/write and search access to user and group root, preventing regular users from accessing this directory.
