1.1.1.2 Ensure mounting of jffs2 filesystems is disabled - lsmod

Information

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

Rationale:

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

Solution

Edit or create a file in the /etc/modprobe.d/ directory ending in .conf
Example: vim /etc/modprobe.d/jffs2.conf
and add the following line:

install jffs2 /bin/true

Run the following command to unload the jffs2 module:

# rmmod jffs2
