"Once Boeing was aware of the nature of the programming blunders in the Honeywell software found by Santamarta, the manufacturer verified in the lab and then on an actual 787 that it was not possible to seize control of a $150-million-ish jetliner via the holes Santamarta discovered."
Erm, one has to be severely doubtful of this. Months after the 2 fatal crashes of the 737 Max, they still have not updated their software, assuming the issue is only software-related.
So, IT security in the plane would really be WAY below in terms of priority.
I doubt a single 787 has even been updated on this very issue.
