6.2.1.3 Ensure auditing for processes that start prior to auditd is enabled

Information

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 or a file in /etc/default/grub.d/ ending in .cfg adding audit=1 to GRUB_CMDLINE_LINUX :

Example:

# printf "\n%s\n" 'GRUB_CMDLINE_LINUX="audit=1"' >> /etc/default/grub.d/40-custom.cfg

Run the following command to update the grub2 configuration:

# update-grub
