1.1.18 Ensure /home partition includes the nodev option

Warning! Audit Deprecated

This audit has been deprecated and will be removed in a future update.

View Next Audit Version

Information

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

Rationale:

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.

Solution

For existing /home partitions, edit the /etc/fstab file and add nodev to the fourth field (mounting options) of the /home entry. See the fstab(5) manual page for more information.
Run the following command to remount /home:

# mount -o remount,nodev /home

Additional Information:

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