| Description |
|---|
| The only legitimate location for device files is the "/dev" directory located on the root partition. The only exception to this is chroot jails. |
| ℹ️ Check |
|---|
| 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. |
| ✔️ Fix |
|---|
| Modify "/etc/fstab" to use the "nodev" option on the "/boot" directory. |
