“4 Disable AppArmor
AppArmor is a security extension (similar to SELinux) that should
provide extended security. In my opinion you don’t need it to
configure a secure system, and it usually causes more problems than
advantages (think of it after you have done a week of
trouble-shooting because some service wasn’t working as expected,
and then you find out that everything was ok, only AppArmor was
causing the problem). Therefore I disable it.”
