1.1.14 Ensure nodev option set on /home partition (Scored)
Profile Applicability
Level 1 - Server Level 1 - Workstation
Description
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.
Audit
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)
Remediation
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
Notes
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.
