1.1.2.3.2 Ensure nodev option set on /home partition

Information

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

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 /home

Solution

- IF - a separate partition exists for /home

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
