This presentation at the 2016 CyCon by Thomas Rid focuses on research into cyber conflict. He provides historical depth to the discussion of cyber war with connections to early research into cybernetics and man-machine interface research.
This is a great overview of activities during a age in the early days of cyber conflict. It provides foundational information any cyber defender should study.
This should help motivate your own actions. We strongly recommend you continue your study of the cyber threat and bring together the best references here at the Things Cyber Threat Actors and Attackers Page.
