I don't have any idea what a 'web control panel back end is' since that is not a stock centos feature. CentOS itself packages updates as soon as possible after they are released and on a non VPS system you would use 'yum update' to install them. And normally you want to do that as soon as possible because when the updates are published, the vulnerabilities that they fix are obvious and often even explained in public. -- Les Mikesell lesmikesell at gmail.com
