1.1.12 Ensure /var/tmp 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 /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,nosuid,nodev,noexec /var/tmp
