# Concepts

*One profile a day keeps the hacker away*
|
|
|
|
There are over 50000 Linux packages and even more applications. It is simply not
|
|
possible to write an AppArmor profile for all of them. Therefore, a question arises:
|
|
|
|
**What to confine and why?**
|
|
|
|
We take inspiration from the [Android/ChromeOS Security Model][android_model] and
|
|
we apply it to the Linux world. Modern [Linux security distributions][clipos] usually
|
|
consider an immutable core base image with a carefully selected set of applications.
|
|
Everything else should be sandboxed. Therefore, this project tries to confine all
|
|
the *core* applications you will usually find in a Linux system: all systemd services,
|
|
xwayland, network, bluetooth, your desktop environment... Non-core user applications
|
|
are out of scope as they should be sandboxed using a dedicated tool (minijail,
|
|
bubblewrap, toolbox...).
|
|
|
|
This is fundamentally different from how AppArmor is usually used on Linux servers
|
|
as it is common to only confine the applications that face the internet and/or the users.
