The document discusses several key ideas about cyber operations:
1) Cyber capabilities shift rapidly, with assumptions needing reevaluation every 5 years. The nature of cyberweapons and thresholds for cyber conflict remain ambiguous.
2) Offense and defense in cyber are indistinguishable and symbiotic, challenging traditional notions of proportionality and legality in conflict. Nation-state operations are also supplemented by powerful non-state actors.
3) Escalation dynamics in cyber are difficult to predict, as seen in wargaming exercises, increasing uncertainty for decision-makers regarding responses to cyber attacks. Bureaucracy may provide the most identifiable signature of state-backed operations.
