What vulnerabilities does each sector have, and do you find commonalities in these (e.g., vis-à-vis cyber threats), or differences that you see in them?

What vulnerabilities does each sector have, and do you find commonalities in these (e.g., vis-à-vis cyber threats), or differences that you see in them?
What are the likeliest futures of the sectors you are reviewing, and how would you improve their protection or reliability/assurance (e.g., what do you see that could be done differently in them, better perhaps on some dimension of critical infrastructure functioning)?
To assist you in your research, you should review pages 6-7 for resources and journals of use to your research, and draw on works from journals and sites such as these:
