1.1.8 Ensure nodev option set on /dev/shm partition - fstab

Information

The nodev mount option specifies that the filesystem cannot contain special devices.

Rationale:

Since the /dev/shm filesystem is not intended to support devices, set this option to ensure that users cannot attempt to create special devices in /dev/shm partitions.

Solution

Edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /dev/shm partition. See the fstab(5) manual page for more information.
Run the following command to remount /dev/shm:

# mount -o remount,noexec,nodev,nosuid /dev/shm
