Ensure access to /etc/cron.yearly is configured

보통레벨 1자동linux

설명

The /etc/cron.yearly directory contains system cron jobs that need to run on an annual 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.
