The USA is inwards the midst of the most resounding policy shift on cyber conflict, 1 amongst profound implications for national safety in addition to the futurity of the internet. The just-released U.S. Cyber Command “vision” accurately diagnoses the electrical flow state of cyber conflict in addition to outlines an appropriate novel operational model for the command: since cyber forces are inwards “persistent engagement” amongst 1 another, U.S. Cyber Command must dive into the fight, actively contesting adversaries farther frontwards in addition to amongst to a greater extent than agility in addition to operational partnerships. The vision, however, ignores many of the risks in addition to how to best address them. Most importantly, the vision does non fifty-fifty recognize the jeopardy that to a greater extent than active defense strength – inwards systems in addition to networks inwards other, potentially friendly nations – persistently, yr afterwards year, mightiness non travel in addition to significantly increases the chances in addition to consequences of miscalculations in addition to mistakes. Even if they are stabilizing, such actions may live incompatible amongst the larger U.S. goals of an opened upwardly in addition to complimentary Internet.
Understanding in addition to dealing amongst these risks volition live a procedure which volition non live completed inwards weeks or months, but, as amongst nuclear weapons, over years in addition to decades. After all, this combat volition non exactly live “persistent” but “permanent.”
Getting to the Idea of Persistent Engagement
The U.S. Cyber Command vision is direct rooted inwards international affairs scholarship on cyber conflict. The thought dates dorsum several years, but momentum picked upwardly amongst a saltation 2016 piece yesteryear Richard Harknett in addition to Emily Goldman, which mentioned the surroundings of persistent offense. The existent image shift started amongst a summertime 2017 article yesteryear Harknett in addition to Michael Fischerkeller, which developed the ideas in addition to noted that inwards a conflict of persistent engagement deterrence was non a specially useful concept. Rather the USA must bring down the operational constraints on U.S. Cyber Command so that it could meliorate engage in addition to scope superiority.
The March 2018 U.S. Cyber Command vision document, “Achieve in addition to Maintain Cyberspace Superiority” stems direct from this Goldman-Fischerkeller-Harknett lineage. Perhaps this is no surprise as both as both Goldman in addition to Harknett were electrical flow or old international relations scholars working at U.S. Cyber Command. Harknett simultaneously published a companion 2300-word Lawfare blog giving additional scholarly oomph to the release of the official vision. The residue of this electrical flow slice volition force as from the vision in addition to that weblog from 1 of its key intellectual parents.
Operating inwards a World of Persistent Engagement
The U.S. Cyber Command vision is a critical document, perhaps the get-go from whatsoever purpose of U.S. authorities that presents a clear-eyed stance of cyber conflict in addition to a project design to bargain amongst it.
The vision begins amongst several work statements, including that, “Achieving superiority inwards the physical domains inwards no small-scale purpose depends on superiority inwards cyberspace. Yet nosotros jeopardy ceding cyberspace superiority.” This is inwards draw amongst many other documents, but the vision goes beyond to a key point, that adversaries usage “continuous operations in addition to activities against our allies in addition to us inwards campaigns brusque of opened upwardly warfare.”
This chemical gene of “continuous operations” is vital: cyber warriors are non exactly waiting dorsum inwards their barracks in addition to their capabilities are non sitting inwards the arsenals. They are constantly engaged on offensive in addition to defensive operations (as good as espionage, a betoken that vision sidesteps, as we’ll beak over below).
Harknett’s companion slice develops this further, that “adversary demeanour intentionally gear upwardly below the threshold of armed aggression has strategic effect.” Normally, having this variety of strategic effect “required territorial aggression (or the threat thereof)” but right away cyber operations “can impact relative powerfulness without traditional armed aggression” into territory. He believes the “status quo is deteriorating into norms that yesteryear default are beingness gear upwardly yesteryear adversaries.”
A critical betoken from Harknett which is easily lost is that cyber strategists, policymakers in addition to scholars must movement framing the conversation “away from the ‘hack,’ ‘breach,’ ‘incident,’ [and] ‘attack.’” Since at that spot is ever contact, conflict is best analyzed as continuous rather than discrete. It is not, to extend this point, an arms race as the arms are beingness used.
Moving from descriptive to prescriptive, U.S. Cyber Command’s vision to scope cyberspace superiority is hence to “defend frontwards as unopen as possible to the source of adversary activity, in addition to persistently rival malicious cyberspace actors.” This requires “scaling to the magnitude of the threat, removing constraints on our speed in addition to agility, in addition to maneuvering to counter adversaries.” In an aside that certainly volition deserve dissertations itself, they also encounter it as a purpose of an “imperative” to “integrate cyberspace operations amongst information operations.”
Understanding Persistent Engagement
The U.S. Cyber Command vision presents a strong instance for persistent engagement but picayune most what it would operationally entail. What would they demand to start doing? What is novel in addition to what changes?
First in addition to foremost, inwards its vision, U.S. Cyber Command calls for fewer operational constraints to allow them to “defend forward” in addition to is clear: “We volition pursue attackers across networks in addition to systems.” They are smart to avoid calling this “active defense” – a controversial concept ofttimes mistakenly associated amongst hacking dorsum – but the thought isn’t far off: yesteryear “seizing the initiative, retaining momentum, in addition to disrupting our adversaries’ liberty of action.”
This way energetically “contesting active campaigns,” yesteryear kicking adversaries out of networks. If, for example, teams of the Cyber Mission Force encounter Russian intelligence forces edifice infrastructure inwards other countries from which to conduct additional espionage or disruptive campaigns against the U.S. in addition to our allies, they volition receive got the authorization to apply exactly about “tactical friction….compelling them to shift resources to defense strength in addition to bring down attacks.”
This mightiness hateful entering inwards those same systems to flora their ain presence, boot out the Russians, or fifty-fifty bring command of the Russian malware. “Fewer operational constraints” tin hateful doing so without call for mother-may-I or fifty-fifty if the Russians are inwards computers or networks inwards the territory of NATO or other allies.
The immediate finish is to tiresome downward adversaries amongst tactical friction. But Harknett sees a larger mechanism. Persistent engagement “can, over time, Pb to a normalization of cyberspace that is less free-for-all in addition to potentially to a greater extent than stable. It is non contradictory to assume that inwards an surroundings of constant activity it volition bring counter activity to moderate demeanour effectively.”
Related to this vision is the gaining continued access to key adversary infrastructure to brand reciprocal threats. This is non purpose of defending frontwards but ensuring that if adversaries desire to handle US infrastructure at risk, in addition to so the President has similar, symmetric options to respond.
And terminal constant contact way potentially increasing cyber intelligence operations inwards “grey” in addition to “red” space, that is inwards non-U.S. computers in addition to infrastructure in addition to those of the adversary. For years, this has been the case, in addition to amongst a novel U.S. vision to triple-down, it may increment farther as all adversaries choose handle of what they can, actively rival each other’s access, in addition to gain novel buy inwards (for example) the network backbone to meliorate improve their intelligence advantages for persistent engagement.
The Right Vision … But Oh So Many Concerns
The U.S. Cyber Command vision, in addition to the associated scholarship, are exactly about of the most of import contributions to agreement cyber conflict. In their diagnosis of the work as 1 of persistent engagement, they are certainly correct.
They may also live right inwards their proposed solution of reduced operational constraints to apply tactical friction in addition to find the initiative. As my colleague Bob Jervis mightiness put it, persistent engagement amongst adversaries exactly mightiness apply negative feedback, gradually nudging conflict dorsum towards lower levels of aggression.
Also, it is clear policymakers in addition to armed forces commanders encounter persistent engagement as only purpose of the solution, in addition to perhaps non fifty-fifty the most of import 1 at that. The Trump direction has continued in addition to expanded a broad gear upwardly of policy tools used yesteryear the Obama administration, including sanctions in addition to indictments, as good as introducing novel ones, most importantly coordinated international attribution of Iranian, Russian in addition to North Korean operations seen as specially insulting to global norms.
Against these solid strengths, at that spot are a number of concerns, or at to the lowest degree topics that demand significantly to a greater extent than attending in addition to study.
The travel yesteryear draw of piece of work organisation is that U.S. Cyber Command does non look to encounter this approach as inwards whatsoever way risky. They say they desire to live “not jeopardy averse but jeopardy aware” in addition to practise cite ii key risks: the lack of plenty of the highly trained people required in addition to the “diplomatic” danger that adversaries “seek to portray our strategy as ‘militarizing’ the cyberspace domain.” But those are the only risks they imagine, or at to the lowest degree are willing to publicly acknowledge.
A longer listing of risks volition start amongst the unproblematic 1 that strategy mightiness non genuinely travel or mightiness receive unintended effects. What if a to a greater extent than engaged frontwards defense strength does non create negative feedback in addition to bring down conflict but instead “positive” feedback, i.e. adversaries seeing the novel active U.S. seat as a challenge to ascent to, rather than 1 from which to dorsum away?
Even accepting that adversaries’ operations receive got been far to a greater extent than aggressive, for certain they tin expire to a greater extent than aggressive still. They may also able to scale faster in addition to meliorate than the United States, either yesteryear relying on artificial intelligence (China or maybe Russia) or hiring or enrolling ever to a greater extent than hackers in addition to proxies to conduct to a greater extent than campaigns using to a greater extent than infected networks in addition to infrastructures than the U.S. tin counter (which whatsoever mightiness scope in addition to all volition try). If it is a strong positive feedback loop, in addition to so each side (including ours) volition expire dorsum to their legislatures or paymasters, call for for yet to a greater extent than budget in addition to looser rules, pointing to the other sides’ newly aggressive frontwards defense strength as proof of their intransigence.
A second, related jeopardy is that adversaries may encounter this non as a reasonable response to their norm-busting demeanour but as a U.S. escalation. China, Islamic Republic of Iran in addition to Russian Federation in all likelihood experience quite confident they are hitting back, non first. The vision does non address espionage or covert action, as these are the labor of the intelligence community. In the U.S. model, these are kept firmly apart fifty-fifty though they are commanded yesteryear the same leaders, from the same bases, in addition to ofttimes usage the same capabilities in addition to fifty-fifty personnel. Only the “hat” of the leader, the flag of the unit, in addition to the authorities of the activity may change.
The Department of Defense has indeed shown restraint inwards Title 10 disruptive armed forces action. If the search includes Title 50 espionage in addition to covert action, in addition to so U.S. restraint is a fleck lost inwards the noise.
Iran cannot live exclusively blameworthy if it felt the demand to respond inwards variety to the Stuxnet attack, attributed to the U.S. in addition to Israel. And non exactly Russian Federation in addition to China, but really unopen U.S. allies felt that NSA espionage, as revealed yesteryear Snowden, were beyond the pale. If it is truthful that the “status quo is deteriorating into norms that yesteryear default are beingness gear upwardly yesteryear adversaries,” in addition to so it is only yesteryear narrowing the number at paw to ignore espionage in addition to covert action, where the USA was ofttimes the state most pushing the limits.
Such operations may receive got been right in addition to skillful in addition to fully inwards U.S. interests but cannot live ignored when trying to empathise conflict dynamics, adversary responses, in addition to determining counters. Nations mightiness live willing to receive got a U.S. frontwards defense strength if they felt the USA would non bring wages of the novel equilibrium, such as amongst widespread network surveillance or covert cyber actions. Unfortunately, Washington DC volition non bring these off the table.
Third, at that spot is the jeopardy that strategy volition travel narrowly but neglect broadly. Cyberspace is critical to all nations in addition to they volition non lightly permit an enduring U.S. “superiority.” Adversaries who discovery their cyber operations hampered may discovery other ways to challenge the novel U.S. superiority inwards ways that are fifty-fifty to a greater extent than averse to U.S. interests. Most U.S. adversaries see picayune distinction betwixt U.S. cyber operations in addition to hostile information, which is “harmful to the spiritual, moral in addition to cultural spheres” of their states. Such states may create upwardly one's heed that if their principal targets are right away blocked yesteryear U.S. Cyber Command, they must conduct to a greater extent than aggressive operations against softer information targets, from mainstream news organizations, code repositories, in addition to elections. This is non a argue to avoid a strategy similar “persistent engagement” but it is a argue to live cautious in addition to curious.
Fourth, fifty-fifty if it is the right strategy, at that spot are high risks of mistakes, misinterpretation in addition to miscalculation. There is no demilitarized zone as betwixt North in addition to Republic of Korea to dissever opposing militaries, no strategic depth to tiresome downward an assault. They volition live constantly grappling. As I’ve written previously,
How tin the fighters inwards the cage, inwards the oestrus of the 2nd known the limits inwards a jibe that volition hand off every day, for years? One side volition expire a fleck as good far, punch a fleck as good hard, force a fob a fleck as good dirty, in addition to ignore the double-tap of “too much” from the other. At what betoken volition U.S. Cyber Command … demand U.S. European Command in addition to NATO to tag into the fight?
After all, the contact discussed inwards this strategy is non exactly constant or persistent. It is forever. It is permanent, a lasting dynamic of safety services engaging inwards unopen (but virtual) combat. If the USA reduces operational constraints, fifty-fifty the most experienced in addition to professional person teams volition brand mistakes, as volition our adversaries’ teams, as has happened countless times inwards wartime. These mistakes may seem similar intentional signaling from the other side, or brazen ignoring of agreed-to norms – in addition to at that spot are few ways to communicate otherwise betwixt armed forces cyber commands.
Certainly, as Department of Defense dives into persistent engagement in addition to defending forward, the personnel in addition to units conducting criminal offense volition only seem to a greater extent than prestigious in addition to command to a greater extent than of the budget. Whether or non this vision “militarizes” cyberspace, a notion U.S. Cyber Command protests, it is probable to proceed to devalue the purpose of mere cyber defense.
Fifth, this strategy may live incompatible amongst nation’s larger policy to “promote an open, interoperable, reliable, in addition to secure network that fosters efficiency, innovation, communication, in addition to economical prosperity.” This may non live achievable, fifty-fifty if the strategy embracing persistent engagement is correct.
As my colleague Adam Segal ofttimes says , the USA has been hither earlier when afterwards the Snowden revelations our allies moved to create stronger European borders inwards cyberspace. U.S. hot pursuit of adversaries into European infrastructure, uninvited, may non larn the thank y'all of grateful allies for liberating their systems from the Russians. And the work is non exactly amongst foreigners, as Segal has pointed out: “As story afterwards story emerged alleging that the NSA undermined encryption, hacked into cables carrying the information of U.S. companies, placed implants in addition to beacons inwards servers in addition to routers, in addition to to a greater extent than ofttimes than non weakened Internet security, Washington struggled to discovery its feet … Policymakers failed to embrace the depth of Silicon Valley’s anger.” Cyberspace may non live able to back upwardly both persistent engagement in addition to silent live open, interoperable, reliable, in addition to secure.
Sixth, this strategy ignores the impact on the repose of us. U.S. Cyber Command mentions several of the most of import dynamics that gear upwardly cyberspace apart, such as disruptive engineering in addition to shifting terrain. But they practise non adequately address that it is, dissimilar other warfighting domains, dominated yesteryear the private sector, civil lodge in addition to individuals. We use, each of us inwards our private in addition to professional person lives, the same technologies as America’s adversaries. If U.S. Cyber Command is to bring down operational constraints, that is probable to mean, for example, to a greater extent than Microsoft zero-day vulnerabilities, to a greater extent than compromised certificate authorities in addition to to a greater extent than authorities access to encrypted communications.
In an era of persistent engagement, the network volition live changed, mayhap fundamentally, in addition to it is difficult to know the broader impact. To paraphrase a quote from my Columbia colleagues, inwards a complex in addition to tightly connected scheme similar the internet, nosotros tin never practise only 1 thing.
Into an Era of Persistent Engagement
Perhaps the imperatives of the novel U.S. Cyber Command vision are the right one, perhaps not. The risks mentioned at that spot in addition to hither may live major concerns or not. No one, non U.S. Cyber Command in addition to non me, tin mayhap know what volition travel inwards such a complex in addition to interconnected systems as both cyberspace in addition to international safety for certain are. What works amongst Russia, a declining powerfulness trying to find global importance, may non travel amongst China. The nation’s response to a cyberspace of persistent engagement must live 1 of experimentation: Try something. Measure what works. Abandon what doesn’t. Repeat.
There are many international crises where fifty-fifty hawks admit at that spot may live no armed forces solution. If persistent engagement leads to positive feedback, amplifying the response from adversaries rather than tamping it down, the USA may receive got to receive got this is 1 of situations. Or, the USA as a technology-dependent republic may non live able to play the game difficult plenty to apply negative feedback. In either case, nosotros may only live able to discovery stability through non-cyber responses.
Making such assessments may live harder amongst the electrical flow dual-hat relationship, where the caput of NSA in addition to U.S. Cyber Command are 1 in addition to the same person. This way the same official is both responsible for executing the strategy, assessing the intelligence to determine if it has successful, the classification of the answer, in addition to the budget either way. This is never a skillful idea, regardless of the talent or professionalism of the leader, in addition to especially non inwards such a high-risk expanse amongst such implications for the U.S. society, innovation, in addition to economy.
Most critically, the USA needs a national strategy for cybersecurity, else U.S. Cyber Command’s vision volition expire the nation’s yesteryear default. Influenza A virus subtype H5N1 larger national strategy, such as 1 built on getting defense strength meliorate than offense, built on leverage, tin assistance construction this vision for operational success.
Superiority is a fine finish for the military, but it tin clash amongst other national, in addition to fifty-fifty national security, priorities. Stability – keeping a lid on cyber conflict so it doesn’t larn out of paw – may live a to a greater extent than important, or achievable, finish than superiority. Warriors don’t desire stability, they desire superiority. That doesn’t hateful that needs to the travel yesteryear priority of the state for a engineering so ubiquitous in addition to fundamental to our success as cyberspace.
During the Cold War, for example, no affair how much it mightiness receive got been disliked yesteryear Strategic Air Command, it was stabilizing for the Soviets to receive got satellites monitoring U.S. missile fields, they knew they’d live less probable to live surprised yesteryear a disarming first-strike. There may live similar tradeoffs betwixt national interests in addition to warfighting success here, but they tin only live found if at that spot is a larger give-and-take of the tradeoffs in addition to a national cyber strategy.
Military in addition to intelligence forces volition live inwards unopen contact, actively contending amongst each other. If this isn’t to spiral out of command at the operational level, at that spot must live military-to-military hotlines in addition to other mechanisms to bring down the chances of miscalculation.
The academic community must get-go recognize the fact of persistent engagement. Theories in addition to models volition fille critical dynamics if they focus on arms races, rely on clear distinctions betwixt peace in addition to state of war or count discrete attacks. Research must right away address issues of stability in addition to escalation control, non to the lowest degree the purpose of “exit ramps” to bring down tensions if cyber conflict gets as good hot in addition to “firebreaks” betwixt the usage of cyber in addition to kinetic force. This may live far easier than inwards the early on nuclear era, as the strategy of the warfighting command was inwards purpose driven yesteryear international relations scholarship. Those briefing the caput of Strategic Air Command, General Curtis LeMay, for certain never had it this good.
More broadly, researchers cannot only focus on how this affects American security, but the larger issues inwards international security. For example, how volition “persistent engagement” acquit upon China-Taiwan dynamics or India-Pakistan?
Forever War
Even when presented amongst the same facts, reasonable people tin disagree in addition to much of our views on national safety are colored yesteryear our early on experiences. Many of mine are from my years at the U.S. Air Force Academy, where most of my instructors fought inwards the skies over Vietnam. All of them (except one) made sure nosotros understood that the state of war could receive got been won, if only the damn politicians had lifted the operational restraints on the military. It wasn’t that simple, of course. They may non receive got been able to win regardless of the tonnage dropped in addition to fifty-fifty if they could receive got the impairment to the social stuff of the USA would never receive got been worth the cost.
Now nosotros are beingness asked in 1 trial again to elevator the operational restraints to allow the armed forces larn on amongst winning. Unleashed, nosotros are told, the nation’s Cyber Mission Force volition grapple amongst the adversary amongst the glorious final result of a “normalization of cyberspace that is less free-for-all in addition to potentially to a greater extent than stable.” We cannot live sure, regardless of how honorable in addition to professional person America’s cyber warriors are, that this fourth dimension volition live different
Cyberspace is non Vietnam. The USA cannot exactly declare “peace amongst honor” in addition to declare the conflict over. Cyberspace is perhaps the most transformative engineering since Gutenberg’s printing press. We right away empathise cyberspace non exactly underpins our lodge in addition to economies but is a domain of persistent engagement betwixt militaries.
This is non exactly constant contact, but a novel forever war. And nosotros must all live cook for that.
