Surprise for you.
Aircraft have had computer systems for quite q while now.

But they haven't been accessible to passengers up to now. With everything on
the same network, anyone could hack into the control network from the
passenger network. That's what is alarming in this case. It would have been
much easier and safer to just install two physically independent networks.

To 'hack' into a system you have to have an input device like a
keyboard.
A touch screen that allows you to select a film channel, audio channel
or Air phone is scarcely going to go any further than that !

Maybe.

My bank's ATMS have touch screens.

One day recently I walked up to them and one clearly had a Microsoft
BSOD.

I didn't try to hack in, but someone might.

Whether or not they are successful depends on how well the system
was designed.

I built networks.
In one building the server ran an Office network, a Student network
and our Tech network.
We could see everything on the other networks.
The students could only see their own network.
The Office staff could only see their own network.

Yes, such is quite common in the real world.

It would appear that your knowledge of computers and IT is right up
there with your knowledge of aviation !

Is that surprising?
