Ensure AppArmor is enabled in the bootloader configuration

中级别 1自动化ros

说明

Configure AppArmor to be enabled at boot time and verify that it has not been overwritten by the bootloader boot parameters. The audit requires apparmor=1 and security=apparmor on every linux line of /boot/grub/grub.cfg. 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

f=/boot/grub/grub.cfg; [ -r "$f" ] || f=/boot/grub2/grub.cfg; [ -r "$f" ] || exit 1
l=$(grep -E '^\s*linux' "$f" | grep -v '/boot/memtest86+')
[ -n "$l" ] || { echo 'no linux lines in grub.cfg'; exit 1; }
bad=$(printf '%s\n' "$l" | grep -Ev '(\s)apparmor=1(\s|$)')
[ -z "$bad" ] && { printf '%s\n' "$l" | grep -Ev '(\s)security=apparmor(\s|$)' | grep -q . && echo 'kernel lines without security=apparmor' || echo compliant; } || echo 'kernel lines without apparmor=1'

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁

edit /etc/default/grub and add the appermor=1 and security=apparmor parameters to the GRUB_CMDLINE_LINUX= line GRUB_CMDLINE_LINUX="apparmor=1 security=apparmor" Run the following command to update the grub2 configuration: # update-grub
