Ensure access to /etc/cron.yearly is configured

中级别 1自动化linux

说明

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.
