1.1.11 Add nodev Option to Removable Media Partitions

Information

Set nodev on removable media to prevent character and block special devices that are present on the removable be treated as these device files.

Rationale:

Removable media containing character and block special devices could be used to circumvent security controls by allowing non-root users to access sensitive device files such as /dev/kmem or the raw disk partitions.

Solution

Edit the /etc/fstab file and add 'nodev' to the fourth field (mounting options). Look for entries that have mount points that contain words such as floppy or cdrom. See the fstab(5)manual page for more information.

Default Value:

OS Default: N/A
