Enable “Jail Apache” in the “Tweak Settings” area, and change users to jailshell in the “Manage Shell Access” area. Consider a more robust solution by using “CageFS on CloudLinux”. Note that this may break the ability to access mailman via Apache.
Install ClamAV within "Manage Plugins".
Update the system (run “yum -y update” on the command line), and reboot the system.
Configure bind-address=127.0.0.1 in /etc/my.cnf, or close port 3306 in the server’s firewall.
Manually edit /etc/ssh/sshd_config and change PermitRootLogin to “without-password” or “no”, then restart SSH in the “Restart SSH” area
Imunify360 delivers sophisticated detection and display of security threats, powered by a self-learning firewall with herd immunity. It blocks attacks in real-time using a combination of technologies, including:
KernelCare provides an easy and effortless way to ensure that your operating system uses the most up-to-date kernel without the need to reboot your server. After you purchase and install KernelCare, you can obtain and install the KernelCare "Extra" Patchset, which includes symlink protection.
mod_ruid2 is enabled in Apache. To ensure that this aids in protecting from symlink attacks, Jailed Apache needs to be enabled. If this not set properly, you should see an indication in Security Advisor (this page) in the sections for “Apache vhosts are not segmented or chroot()ed” and “Users running outside of the jail”. If those are not present, your users should be properly jailed. Review Symlink Race Condition Protection for further information.
