<code>yum-cron</code> will work just like Debian's [[unattended upgrades]]. Use it to keep your RedHat or CentOS* host up-to-date with security patches and even regular package updates. yum-cron is an alternate interface to [[yum]], optimized for cron.
Similarly, you can use <code>yum autoremove</code> to remove obsolete packages from your system.
