Details

Configure grub2 so that processes that are capable of being audited can be audited even if they start up prior to auditd startup. Audit events need to be captured on processes that start up prior to auditd , so that potential malicious activity cannot go undetected.

Solution

Edit /etc/default/grub and add audit=1 to GRUB_CMDLINE_LINUX: GRUB_CMDLINE_LINUX=”audit=1″ Run the following command to update the grub2 configuration: # grub2-mkconfig -o /boot/grub2/grub.cfg This recommendation is designed around the grub2 bootloader, if another bootloader is in use in your environment enact equivalent settings.
