U.S. Cyber Strategy of Persistent Engagement & Defend Forward: Implications for the Alliance and Intelligence Collection
The 2018 U.S. Cyber Command vision and the Department of Defense Cyber Strategy embody a fundamental reorientation in strategic thinking. Much has been written about the implications of U.S. change in strategic doctrine for great power dynamics. Yet, less systematic attention, has been devoted to the strategy’s implications for the alliance and intelligence collection. The purpose of this Perspective is to conduct a benefit-risk assessment of the US strategy on these issues. Whilst the U.S.’s mission to persistently engage with adversaries may have benefits for alliance relationships, the paper identified four avenues how the strategy leads to negative implications for the alliance i) loss of trust due to offensive cyber effects operations in allied systems or networks; compromise of allied intelligence operations and capabilities; iii) exploitability of the strategy by adversaries; and iv) the implementation (and justification) of persistent engagement by other countries. The paper suggests several ways forward, including the promoting of new NATO-memorandum of understanding on cyber operations.
