1.1.1.2 Ensure mounting of freevxfs filesystems is disabled - lsmod

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.
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
```
