Ensure Apache AppArmor Profile is in Enforce Mode

低レベル 2自動apache

説明

AppArmor profiles may be in one of three modes: disabled, complain or enforce. In the complain mode, any violations of the access controls are logged but the restrictions are not enforced. Also, once a profile mode has been changed, it is recommended to restart the Apache server, otherwise the currently running process may not be confined by the policy. aa-status must list running apache2 processes only under "processes are in enforce mode" (none unconfined or in complain mode); fails when Apache is not running. Not applicable without /etc/apparmor.d.
