Fix Recommendation

Modify "/etc/fstab" to use the "nodev" option on the "/boot" directory.

Check Contents

Verify that the "/boot" mount point has the "nodev" option with the following command:

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

/dev/sda1 on /boot type xfs (rw,nodev,relatime,seclabel,attr2)

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