Firstly - not exactly a forensic question, but it applies to some questions I'm being asked in the mobile security field
I'm talking about how the Android OS enforces separation between processes. From reading some background, I see the device has three parts
- the hardware
- the linux kernel/OS
- the application runtime (the time/lifecycle during which a software app is running)
Now I'm from a networking background so I'm not sure how you troubleshoot issues on mobile devices, but I'd imagine it would be the same as troubleshooting on a PC - since an android s2 for example is a mobile computer (has ram, cpu, ephemeral storage) so therefore I was wondering if I could apply the OSI layer to it
If so, device hardware would be physical layer, linux kernel/android os would be (not sure?) and android runtime would be application?
Or now I've just come to realise that these parts may encompass multiple layers in the osi model
Thanks in advance for any insight you can provide
I am not sure to understand the "scope" (or the "idea" behind). 😯
OSI model is an attempt (which became a standard) to describe a communication system.
It's layers are (mostly) specific and limited to a communication system, though you can find similarities between such a model and that of a computing device, you can as well find similarities between almost *any* conceptual model and a PC, or a mobile device or *whatever* manages/transmits/computes data.

is a representation that applies to *almost anything*, as well as this one (which is actually Linux specific)

What was the question? ?
