Is this your own work? Show HN is for sharing something you've personally created. See https://news.ycombinator.com/showhn.html

I ask because I don't see any indication of that on this post or the other one (https://news.ycombinator.com/item?id=39867639).

No, this is my work (see the link in my profile). However, I should thank CHEF-KOCH for the post, as I should have done it months ago...

While you are here, have a look at the doc: https://apparmor.pujol.io It is not stable yet, but it is promising.

Ok! I'm glad I left Show HN in the title then :) Thanks for clarifying.

On the XZ back door thread multiple people are shitting on systemd I, but I think its sandboxing model is easier because you just couple the expected behavior of your application along with the unit. Interested people should look here[1] and [2] in case you need resource limitations, like limiting the amount of CPU a process can use.

Of course, there is no way to isolate a backdoored piece of code running in the same address space as yours.

These have to be distributed in the operating system by default. Ubuntu ships some, but they sandbox limited set of applications.

I installed some of these anpparmo profiles in Ubuntu, and had to spend a lot of time profiling and fixing permissions. This was an ever changing process, also required security knowledge. Eventually, I removed them.

You are right, the plan is to included by default. And given time it will be [0].

If you can report some logs to fix your issue that would be nice.
