Ensure access to /etc/cron.yearly is configured

MediaNivel 1Automatizadalinux

Descripción

The /etc/cron.yearly directory contains system cron jobs that run on an annual basis. Files in this directory are edited directly by system administrators rather than through the crontab command. The commands below restrict read, write, and search access to root only, preventing regular users from accessing this directory.
