Ensure all AppArmor Profiles are enforcing

보통레벨 1자동ros

설명

AppArmor profiles define what resources applications are able to access. The audit runs apparmor_status and requires every loaded profile to be in enforce mode and no unconfined processes. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

점검 방법

감사 방식: 셸 명령

shell

out=$(apparmor_status 2>/dev/null) || exit 1
l=$(printf '%s\n' "$out" | awk '/profiles are loaded/{print $1; exit}')
c=$(printf '%s\n' "$out" | awk '/profiles are in complain mode/{print $1; exit}')
u=$(printf '%s\n' "$out" | awk '/processes are unconfined/{print $1; exit}')
[ "${l:-0}" -gt 0 ] || { echo 'no AppArmor profiles loaded'; exit 1; }
[ "${c:-0}" -eq 0 ] && [ "${u:-0}" -eq 0 ] && echo compliant || echo "complain: ${c:-0}, unconfined: ${u:-0}"

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

Run the following command to set all profiles to enforce mode: # aa-enforce /etc/apparmor.d/* Any unconfined processes may need to have a profile created or activated for them and then be restarted.
