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

install freevxfs /bin/true

Run the following command to unload the freevxfs module:

# rmmod freevxfs
