2.21 Disable Mounting of hfs Filesystems

Information

The hfs filesystem type is a hierarchical filesystem that allows you to mount Mac OS
filesystems.

*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 the file /etc/modprobe.d/CIS.conf and add the following line-install hfs /bin/true
