1.1.14 Ensure nodev option set on /home partition (Scored)

Level 1 - Server 
Level 1 - Workstation

The nodev mount option specifies that the filesystem cannot contain special devices.

Since the user partitions are not intended to support devices, set this option to ensure that users cannot attempt to create block or character special devices.

If a /home partition exists run the following command and verify that the nodev option is set on /home.

# mount | grep /home 
/dev/xvdf1 on /home type ext4 (rw,nodev,relatime,data=ordered)

Edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /home partition. See the fstab(5) manual page for more information.

# mount -o remount,nodev /home

The actions in this recommendation refer to the /home partition, which is the default user partition that is defined. If you have created other user partitions, it is recommended that the Remediation and Audit steps be applied to these partitions as well.
