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
Parameter:
[yes/no]
Technical Mechanism:
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
