1.1.1.3 Ensure mounting of jffs2 filesystems is disabled (Scored)

Level 1 - Server 
Level 1 - Workstation

The jffs2 (journaling flash filesystem 2) filesystem type is a log-structured filesystem used in flash memory devices.

Removing support for unneeded filesystem types reduces the local attack surface of the server. If this filesystem type is not needed, disable it.

Run the following commands and verify the output is as indicated:

# modprobe -n -v jffs2 
install /bin/true 
# lsmod | grep jffs2 
<No output>

Edit or create the file /etc/modprobe.d/CIS.conf and add the following line:

install jffs2 /bin/true
