1.1.1.2 Ensure mounting of freevxfs filesystems is disabled - modprobe

Information

The freevxfs filesystem type is a free version of the Veritas type filesystem. This is the
primary filesystem type for HP-UX operating systems.

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/freevxfs.conf
and add the following line:

install freevxfs /bin/true

Run the following command to unload the freevxfs module:

rmmod freevxfs
