# 1.1.1.5 Ensure mounting of hfsplus filesystems is disabled # # 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 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 hfsplus # install /bin/true # # lsmod | grep hfsplus # # # Remediation # =========== # Edit or create the file /etc/modprobe.d/CIS.conf and add the following line: # # install hfsplus /bin/true # parameters: linux: system: kernel: module: hfsplus: install: command: /bin/true
