The novel U.S. Cyber Command (USCYBERCOM) vision as well as the Department of Defense Cyber Strategy embody a key reorientation inwards strategic thinking. With the publication of these documents, as good as 2017 National Security Strategy as well as the 2018 National Defense Strategy, at that topographic point is a general conception among expertsthat the U.S. has, for the first of all time, articulated a strategy that really appreciates the unique “symptoms” of cyberspace. The documents recognize that at that topographic point is a novel structural laid upwardly of dynamics associated amongst the novel domain of mesh that has incentivized a novel approach to powerfulness competition—in particular, that hostile or adversarial demeanor below the threshold of armed laid upwardly on could withal hold upwardly strategically meaningful (that is, alter the residue of power).
Yet most cyber experts cause got also argued that the ‘medicine’ prescribed past times the Defense Department as well as USCYBERCOM should hold upwardly farther scrutinized. Indeed, the side effects of the strategy of “persistent engagement” as well as “defense forward” are silent ill-understood. As nosotros cause got argued elsewhere, a U.S. that is to a greater extent than powerful inwards mesh does non necessarily hateful 1 that is to a greater extent than stable or secure. More inquiry is required to amend sympathise adversarial adaptive capacity as well as escalation dynamics.
We should greenback that the Department of Defense dictionary has non yet provided a formal Definition of “defending forward.” We suspect the formal Definition that is ultimately adopted volition hold upwardly similar to the earlier concept of “counter cyber,” though amongst an emphasis on adversarial cyber campaigns (instead of ‘activities’): “A mission that integrates offensive as well as defensive operations to attain as well as hold a desired score of mesh superiority. Counter-cyber missions are designed to disrupt, negate, and/or destroy adversarial mesh activities as well as capabilities, both before as well as afterward their employment.”
Scholarship to appointment has mainly pointed out that this novel U.S. strategic thinking could hold upwardly escalatory, but it has non sought to piece out the specific causal mechanisms as well as scenarios as to how the consequences of the strategic shift may unfold.
In a forthcoming article, role of an edited volume on offensive cyber operations published past times the Brookings Institution (entitled “Bytes, Bombs, as well as Spies: Strategic Dimensions of Offensive Cyber Operations”), nosotros systematically address closed to of these conflict outcomes. Specifically, nosotros consider the 4 full general outcomes possible over fourth dimension amongst 2 outcome variables: a to a greater extent than (or less) powerful U.S. as well as a to a greater extent than (or less) stable cyberspace.
From the U.S. standpoint, the optimal outcome is a U.S. that is to a greater extent than powerful inwards mesh along amongst a to a greater extent than stable cyberspace. Indeed, from the U.S. standpoint, the sometime volition atomic number 82 to the latter. H5N1 to a greater extent than stable mesh volition involve norms of acceptable behavior, less conflict as well as then on.
One path towards this rosy outcome is that the strategy does what it is said to do: Creates important friction as well as makes it hard for adversaries to operate effectively. Adversaries realize that the U.S. strategy of persistent engagement makes it to a greater extent than hard to acquit diverse offensive cyber operations, as well as they cause got no strong incentives to escalate as it may trigger a U.S. response inwards the conventional domain. USCYBERCOM has the payoff from the beginning.
Some argued at the first of all USCYBERCOM symposium that persistent engagement may first of all atomic number 82 to a worsening province of affairs before it gets better. This outcome is possible nether 1 of 2 conditions. First, USCYBERCOM could initially hold upwardly unable to seize the inaugural from a capacity perspective, but choke increasingly amend at it inwards the future. This may good hold upwardly true: USCYBERCOM is silent continuing to prepare its cyber capacity. Even though the Cyber Mission Force (CMF) has achieved sum operational capability, it volition convey fourth dimension for the novel workforce to operate capably as well as ensure the effective coordination of all units.
The mo status is that other actors could increment their hostile cyber activity inwards the brusk term, but choke less hostile inwards the long run. This status is much less probable to hold upwardly true: Other actors are probable to suit to U.S. activities over fourth dimension rather than to trim down their ain activities, as well as the expected number of actors amongst hostile intent inwards this infinite is probable to increment over time. For example, FireEye latterly reported on the “rise of the rest,” arguing that the footing has seen a growing number of advanced persistent threat (APT) groups attributed to countries other than Russian Federation or China.
Another to a greater extent than powerful as well as to a greater extent than stable province of affairs analyzed inwards the newspaper could—perhaps paradoxically—be described as “deterrence through a strategy of persistence.” In this especial outcome, the psyche threat actors are initially cautious to act, next the unloosen of U.S. novel strategy. However, this is unlikely: Other actors volition in all likelihood non exhibit caution to run into which agency the current of air blows before acting. An excerpt from Lt. Gen. Nakasone’s nomination hearing to serve as managing director of the NSA is telling:
Sen. Sullivan: They [our adversaries] don’t fearfulness us.
Gen.Nakasone: They don’t fearfulness us.
Sen. Sullivan: So, is that good?
Gen. Nakasone: It is non good, Senator.
As a follow-up to Sen. Dan Sullivan’s question, Sen. Ben Sasse asked: “Is at that topographic point whatever response from the U.S. Government that’s sufficient to alter the Chinese behavior?... Do yous recall there’s whatever ground the Chinese should hold upwardly worried near U.S. response at the present?” Lt. Gen. Nakasone responded: “Again, I recall that our adversaries cause got non seen our response inwards sufficient item to alter their behavior.” In describe of piece of work amongst this notion, it is unlikely that the publication of the strategies solitary volition hold upwardly sufficiently threatening to atomic number 82 to this optimal outcome.
Less Optimal Outcomes
One path towards escalation involves adversaries becoming to a greater extent than aggressive as well as conducting attacks that are highly disruptive to society—in other words, adversary activity leads to a less stable cyberspace. This could hold upwardly the outcome of either an adversary’s increased willingness to acquit attacks using existing capacities or increased capacities of the adversary. Indeed, amongst honor to the latter, the U.S. vision—and associated changed course of teaching of action—may encourage other actors to grow their budgets to acquit offensive cyber operations. The proliferation literature on weapons of majority devastation has extensively covered the role of special interests inwards stimulating demand for weapon development. This makes it a strong possibility that the novel U.S. vision tin hold upwardly used past times those groups inside a given province favoring a growing cyber ascendance to justify as well as antechamber for increased state of war machine spending.
A mo possibility is that increased U.S. offensive cyber activity that operates below the threshold of armed laid upwardly on activity reduces the value of cyber norms of demeanor that back upwardly a to a greater extent than stable cyberspace. Even today, closed to observers believe that the high bird of offensive activity inwards mesh today demonstrates quite forcefully that nations reveal value inwards conducting such activity, as well as that such activity points to the difficulty of establishing a to a greater extent than peaceful cyber norms regime. These observers fence that at that topographic point is no ground to human face that increasing the U.S. contribution to such activity worldwide volition arrive easier to found such a regime. Finally, a tertiary possibility is that increased U.S. offensive cyber activity volition complicate diplomatic relations amongst allies as well as other nations whose cyber infrastructures are used inwards back upwardly of such activity.
Increased aggressiveness past times adversaries could also outcome from growing incentives to acquit offensive cyber operations of a highly disruptive nature. In this case, heightened aggressiveness mightiness hold upwardly a symptom of the U.S. strategy really beingness effective inwards making the U.S. to a greater extent than powerful. Consider, for example, the electrical current state of war against the Islamic State: losing territory as well as traveling steal inwards the Middle East, the terrorist scheme is said to hold upwardly keen to recruit followers inwards Europe as well as other places inwards the footing to acquit attacks exterior of Republic of Iraq as well as Syria. These attempted majority killings are a agency to exhibit that the grouping silent needs to hold upwardly feared as well as potentially to aid recruiting—but they exercise non alter the residue of powerfulness inwards the region. Actors inwards mesh mightiness choke to a greater extent than noisy as well as aggressive purely to increment friction, gain attending as well as then on —and mayhap also to influence international world persuasion inwards ways that drive the U.S. toward changing its strategy.
Finally, worst-case outcomes—that is, a U.S. that is less powerful inwards mesh along amongst a less stable cyberspace—could stalk from a multitude of sources. One possibility is that the U.S. could overplay its manus inwards damage of cyber capabilities. The USCYBERCOM is operating inwards a infinite inwards which it has to seize the inaugural against a large as well as ever-growing number of actors. The dangers of fighting on multiple fronts—even for the most capable actors—are good known from conventional warfare. As the number of potential cyber “fronts” is much higher compared to conventional warfare, the risks of overextension cause got choke much higher as well. The Defense Department vision’s explicit focus on Russian Federation as well as China, next the USCYBERCOM vision’s quiet on the number of priorities, makes us less concerned near this scenario —though it is silent a possibility.
Final Word
After initial, prompt analysis from the scholarly community of the strategies, the province right away needs systematic inquiry on how persistent engagement as well as defence strength forwards may play out. We believe that outcome-based analysis is 1 desired variety out of inquiry which could hold upwardly expanded. (One of import limitation of our analysis is that nosotros exercise non pay sufficient item to risks of the U.S. non changing its course of teaching of action.)
Other inquiry inwards this champaign is would hold upwardly helpful as well—consider instance study analyses. Russian Federation conducts real different cyber campaigns to impact U.S. sources of powerfulness than does China, as well as defence strength forwards volition thence human face real different inwards both cases. But how the U.S. should defend forwards for each specific case, inwards monastic say to optimize powerfulness gains as well as trim down escalation, has non yet been addressed. This go is needed.
Also, the inquiry is non but how adversaries volition response to the alter inwards U.S. strategy. It is as of import to analyze the demeanor of allies. With the implementation of this strategy, volition allies follow? Or volition they stick to the full general deterrence-type strategies?
The bottom line? More inquiry is needed—let’s larn to it.
