Fix Recommendation

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

Check Contents

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

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

/dev/sda1 on /boot type xfs (rw,nosuid,relatime,seclabe,attr2,inode64,noquota)

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