1.1.1.3 Ensure mounting of hfs filesystems is disabled - modprobe

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 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/hfs.conf
and add the following line:

install hfs /bin/true

Run the following command to unload the hfs module:

# rmmod hfs
