To enable strict FIPS compliance, the fips=1 kernel option needs to be added to the kernel command line during system installation so key generation is done with FIPS-approved algorithms and continuous monitoring tests in place. Configure the operating system to implement DoD-approved encryption by following the steps below: The fips=1 kernel option needs to be added to the kernel command line during system installation so that key generation is done with FIPS-approved algorithms and continuous monitoring tests in place. Users should also ensure that the system has plenty of entropy during the installation process by moving the mouse around, or if no mouse is available, ensuring that many keystrokes are typed. The recommended amount of keystrokes is 256 and more. Less than 256 keystrokes may generate a non-unique key. Install the dracut-fips package with the following command: # yum install dracut-fips Recreate the "initramfs" file with the following command: Note: This command will overwrite the existing "initramfs" file. # dracut -f Modify the kernel command line of the current kernel in the "grub.cfg" file by adding the following option to the GRUB_CMDLINE_LINUX key in the "/etc/default/grub" file and then rebuild the "grub.cfg" file: fips=1 Changes to "/etc/default/grub" require rebuilding the "grub.cfg" file as follows: On BIOS-based machines, use the following command: # grub2-mkconfig -o /boot/grub2/grub.cfg On UEFI-based machines, use the following command: # grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg If /boot or /boot/efi reside on separate partitions, the kernel parameter boot=<partition of /boot or /boot/efi> must be added to the kernel command line.
