1.1.8 Ensure nodev option set on /var/tmp partition

Information

Since the /var/tmp filesystem is not intended to support devices, set this option to ensure
that users cannot attempt to create block or character special devices in /var/tmp.

Solution

Edit the /etc/fstab file and add nodev to the fourth field (mounting options) for
the /var/tmp partition. See the fstab(5) manual page for more information. Run the following command to remount /var/tmp - # mount -o remount,nodev /var/tmp
