1.1.1.4 Ensure mounting of hfs filesystems is disabled (Scored)
Profile Applicability
Level 1 - Server Level 1 - Workstation
Description
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.
Audit
Run the following commands and verify the output is as indicated:
# modprobe -n -v hfs install /bin/true # lsmod | grep hfs <No output>
Remediation
Edit or create the file /etc/modprobe.d/CIS.conf
and add the following line:
install hfs /bin/true
