Fix Recommendation

Configure the "/etc/fstab" to use the "nosuid" option on the /boot/efi directory.

Check Contents

Note: For systems that use BIOS, this is not applicable.

Verify the /boot/efi directory is mounted with the "nosuid" option with the following command:

$ sudo mount | grep '\s/boot/efi\s'

/dev/sda1 on /boot/efi type vfat (rw,nosuid,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=winnt,errors=remount-ro)

If the /boot/efi file system does not have the "nosuid" option set, this is a finding.
