Description: 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 . Audit: Verify that the nodev option is set if a /var/tmp partition exists. Run the following command and verify that nothing is returned: # mount | grep -E 's/var/tmps' | grep -v nodev Remediation: 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

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
