Dr. Jacquelyn G. Schneider is an assistant professor in addition to affiliate faculty at the Center for Cyber Conflict Studies at the U.S. Naval War College. This article represents her views lone in addition to create non stand upwards for those of the U.S. Naval War College, the U.S. Navy, or the Department of Defense. You tin follow her @jackiegschneid. Last week, Jason Healey argued that “there is straight off a well-documented event of cyber deterrence,” pointing to a study of conversations inside the Obama administration. Some White House officials argued against a cyberattack, citing asymmetric vulnerabilities inwards tit for tat engagements inside the cyber domain. Healey highlights a powerful representative of cyber restraint inside the Obama administration, but is it deterrence? The the States has likewise exercised restraint inwards the nuclear domain, but it is unclear fifty-fifty straight off whether that restraint is a resultant of adversary deterrence efforts or a normative nuclear taboo. So what is driving the cyber restraint Healey identified? In companionship to empathise the motivations behind cyber behaviors, I performed a longitudinal analysis of strategic state of war games conducted at the Naval War College from 2011-2016. These free-play games, which characteristic 150-200 U.S. authorities experts in addition to senior leader players, situate players inside crisis scenarios in addition to and so let them to play all instruments of national ability to resolve the crisis. Over the years that I analyzed, these state of war games varied the adversary, the intensity of the crisis, in addition to the players. Like the development of cyber operations inwards existent life, the means cyber capabilities were designed inwards the games evolved inwards complexity, representing the institutions in addition to capabilities that developed from 2011 to 2016. Bottom line: a lot of things changed betwixt the games.
However, what remained remarkably consistent across the games was how players utilized cyber operations. In 5 of the vi games, players launched offensive cyber operations solely later conventional weapons conducted destructive attacks. Additionally, players were to a greater extent than willing to house systems on nuclear warning than to launch cyberattacks or fifty-fifty cyber-enabled data operations. Over in addition to over players cited concerns nearly escalation inwards their cyber restraint, articulating fears that cyberattacks could “lead to nuclear war.” Further, inwards all of the vi games, despite large scale adversary cyberattacks (up to nuclear effects inwards allied countries), none of the “blue” teams chose to respond to cyberattacks. In 1 game, a histrion explained, “this is cyber—it’s different psychologically.” In all of these games, players were told who had attacked them inwards cyberspace, essentially priming them for retaliation. The lack of back upwards for retaliation inwards these games is, therefore, peculiarly compelling.
This query suggests 2 types of restraint: restraint inwards using cyber operations in addition to an overall restraint inwards responding to cyber operations. What causes this restraint? Is it deterrence or is it a cyber taboo? These games couldn’t definitively response this puzzle, but they create propose a serial of potential hypotheses nearly cyber restraint. First, restraint inwards utilizing cyber operations could live on a uniquely U.S. phenomenon tied to a perception of asymmetric cyber vulnerabilities combined alongside overwhelming conventional superiority (what Healey’s article alludes to). In other words, why opened upwards the Pandora box of cyber operations when the the States has the pick to respond to whatever meaning problems alongside economical penalty or military machine might? H5N1 secondary hypothesis suggests that cyber restraint derives from a simulated cyber-nuclear equivalency inwards which the institutional legacy of Strategic Command in addition to the narrative of “strategic” cyber weapons has led to an extension of the nuclear taboo to the cyber domain. These hypotheses are largely agnostic to the adversary—mainly because the games I analyzed featured different adversaries alongside different cyber, conventional, in addition to nuclear capabilities. Restraint was consistent despite these threat differences, suggesting that cyber restraint was non a production of adversary-tailored deterrence but instead internally derived incentives.
Perhaps to a greater extent than puzzling is why these games likewise demonstrate restraint when responding to cyber operations—a phenomenon non constitute inwards the nuclear domain. Once again, this could live on a strictly U.S. aeroplane of restraint, inwards which the United States—as the largest economical in addition to military machine power—can withstand meaning cyberattacks without retaliation because it relies on a greater conventional in addition to nuclear superiority. However, at that topographic point could live on a to a greater extent than generalizable explanation which links cyber restraint to emotions in addition to argues that the virtual in addition to new threat of cyber operations neglect to generate the variety of cope or flying gut reaction created past times to a greater extent than evolutionarily-primed threats. If this concluding hypothesis is true, in addition to so the restraint inwards cyber response may permeate beyond U.S. borders in addition to propose that cyber operations are highly unlikely to Pb to escalation inwards other domains.
Finally, the 1 state of war game which did non display cyber usage restraint has of import implications for foreshadowing the long-term pull of the cyber taboo. In that game, the histrion leading the bluish squad executed an extraordinarily risk-acceptant “escalate to dominate” strategy that featured early on starting fourth dimension usage of cyberattacks against a serial of domestic in addition to military machine targets followed past times a large-scale conventional offensive. This game highlighted how of import the ask chances proclivity in addition to personality of leaders are to when in addition to how cyber operations are used. Previous research highlighted the large purpose that ask chances aversion played inwards the Obama direction in addition to restraint across a serial of domains. The Trump direction is much to a greater extent than ask chances acceptant, which may Pb to less incentives for self-restraint inwards cyberspace.
