MACF-6208 - AppArmor status
This test determines the status of AppArmor, on systems like Debian, Ubuntu, openSUSE, and others.
How to solve
Two common security frameworks are SELinux and AppArmor. The choice for which framework on systems running Debian and Ubuntu is easy. Only AppArmor is available. This is because only support for this framework is compiled into the Linux kernel. When possible enable the capabilities of AppArmor. This helps to restrict processes from accessing data they are not supposed to.
If you really want to harden your Ubuntu systems, then AppArmor is a great addition. This framework defines what running processes can do, or access. Think of it like a prison guard that continuously monitors its prisoners, to ensure they only do activities that are allowed. The allowed activities are stored in policy files, together with the related processes.
