1.1.7.2 Ensure nodev option set on /home partition

Information

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

Rationale:

Since the /home filesystem is not intended to support devices, set this option to ensure that users cannot create a block or character special devices in /var.

Solution

Edit the /etc/fstab file and add nodev to the fourth field (mounting options) for the /home partition.
Example:

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

Run the following command to remount /home with the configured options:

# mount -o remount /home
