1.1.1.5 Ensure mounting of hfsplus filesystems is disabled - modprobe

Information

The hfsplus filesystem type is a hierarchical filesystem designed to replace hfs 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 the file /etc/modprobe.d/CIS.conf and add the following line:

install hfsplus /bin/true

Run the following command to unload the hfsplus module:

# rmmod hfsplus
