Ensure mounting of hfs filesystems is disabled

中级别 1自动化ros

说明

The hfs filesystem type is a hierarchical filesystem that allows you to mount Mac OS filesystems. The audit requires the hfs module to be unloaded and blocked (modprobe -n -v reports install /bin/true). Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

shell

command -v modprobe >/dev/null 2>&1 || exit 1
grep -qw '^hfs' /proc/modules 2>/dev/null && { echo 'hfs is loaded'; exit 1; }
cfg=$(modprobe -n -v hfs 2>&1)
case "$cfg" in *'install /bin/true'*|*'install /bin/false'*|*'not found'*) echo compliant; exit 0 ;; esac
modprobe --showconfig 2>/dev/null | grep -Eq '^\s*install\s+hfs\s+/bin/(true|false)' && echo compliant || echo 'hfs can be loaded'

预期输出: compliant
