Configure grub so that processes that are capable of being audited can be audited even if they start up prior to auditd startup. Rationale: Audit events need to be captured on processes that start up prior to auditd , so that potential malicious activity cannot go undetected. Note: This recommendation is designed around the grub2 bootloader, if LILO or another bootloader is in use in your environment enact equivalent settings.
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
