This description was written by a machine and published without a person checking it. It is what the agent made of this grouping, and not a statement anybody has stood behind.
What the threat is said to be
A subject the papers are about. The loosest grouping, and the one to reach for last.
Accounts of what threatens critical infrastructure, from sources of different kinds -- agency advisory, think-tank survey, textbook, measurement study. They are grouped rather than reconciled, and the differences between them are the point. Membership requires the work to assert what the threat is, not to defend against one.
