1.1.4.4 Ensure nodev option set on /var/tmp partition

Audit#

Verify that the nodev option is set for the /var/tmp mount. Run the following command to verify that the nodev mount option is set. Example: 

# findmnt --kernel /var/tmp
/var/tmp    /dev/sdb ext4   rw,nosuid,nodev,noexec,relatime,seclabel
IF output is produced, ensure it includes the nodev option

Remediation#

IF the /var/tmp partition exists, edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /var/tmp partition.

Example: 

<device> /var/tmp   <fstype>    defaults,rw,nosuid,nodev,noexec,relatime    0 0

Run the following command to remount /var/tmp with the configured options: 

# mount -o remount /var/tmp
