1.1.13 Ensure /var/tmp partition includes the nodev option
The nodev mount option specifies that the filesystem cannot contain special devices. Rationale: 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 .
For existing /var/tmp partitions, edit the /etc/fstab file and add nodev to the fourth field (mounting options) of the /var/tmp entry. See the fstab(5) manual page for more information. Run the following command to remount /var/tmp: # mount -o remount,nodev /var/tmp
