Next step after install cPanel

Hi

This is a basic steps to configure your server:
Check Server Time: date
Update to latest kernel
Install a Firewall: I recommend CSF
Tweak Settings (Configuration Guide) -> Tweak Settings
Enable Apache mod_userdir protection
Disable Compiler Access

And a lot of things...

Ps: CSF has one scan to help you with some configs
CSF installation: http://www.configserver.com/free/csf/install.txt
