1.1.20 Disable Mounting of jffs2 Filesystems - install jffs2 /bin/true'

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 server. 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: /etc/modprobe.d/jffs2.conf
Add the following line:

install jffs2 /bin/true

Default Value:

OS Default: N/A
