1.1.1.5 Ensure mounting of hfsplus filesystems is disabled (Scored)
Profile Applicability
Level 1 - Server Level 1 - Workstation
Description
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 server. If this filesystem type is not needed, disable it.
Audit
Run the following commands and verify the output is as indicated:
# modprobe -n -v hfsplus install /bin/true # lsmod | grep hfsplus <No output>
Remediation
Edit or create the file /etc/modprobe.d/CIS.conf and add the following line:
install hfsplus /bin/true
