What is the Kali Linux Access Control System type?

I'm taking an introduction to security course and we're supposed to write a report about the Access Control System of the computer we use as though we were an attacker trying to break our own system. I can't figure out how to tell what the access control system type is. Like I've studied what the different types are, though I might need to rewatch the lecture, but I'm not really sure what to look at on the system to take screenshots of and really deduce what the access control system type is. :confused:

I don't think Kali comes with it enabled by default, but you can add it to any Linux system;
