Ensure permissions on bootloader config are configured

中级别 1自动化ros

说明

The grub configuration file contains information on boot settings and passwords for unlocking boot options. The grub configuration is usually grub.cfg stored in /boot/grub/. The audit requires /boot/grub/grub.cfg owned by root:root with no group or other permissions. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

检查方式

审计方法: Shell 命令

shell

[ -e /boot/grub/grub.cfg ] || { echo '/boot/grub/grub.cfg not found'; exit 1; }
set -- $(stat -Lc '%a %u %g' /boot/grub/grub.cfg) || exit 1
m=$((8#$1)); [ $((m & ~8#0700)) -eq 0 ] || { echo "/boot/grub/grub.cfg mode $1 exceeds 0700"; exit 1; }
[ "$2" = 0 ] || { echo "/boot/grub/grub.cfg uid $2"; exit 1; }
case " 0 " in *" $3 "*) echo compliant ;; *) echo "/boot/grub/grub.cfg gid $3" ;; esac

预期输出: compliant
