I've been asked to take over a Linux server that runs WHM and cPanel, and I was wondering about what limitations I have when securing it.
Can I login via SSH, change ports, add/update users and keys, install applications (such as fail2ban, knockd, Tripwire, etc) and not interfere with cPanel and WHM? When they update, will they interfere with my installs (eg. revert back to default settings)?
If there is no interference, that's excellent, and if so, another question.
Has anyone managed to install and configure Snort to run alongside WHM? Any problems? Are there any guides out there that would help me?
Thanks for any help that can be given!
