It appears that he did, which would be standard practice for people in his corner of the hacking world. Boeing said there is no problem, so nothing to secure. Not everyone agrees.
I would suggest that a good place to start thinking about this, even before digging into details, is with this question: "What were the system architects thinking when they decided that it was OK to have an inflight entertainment system that
is not physically separated from flight control systems?" Some air gaps are really very important.
