The Four Quadrants
In his article, The Fourth Quadrant, Professor Zittrain develops a four quadrant framework for thinking about the Internet. This framework looks at two criteria: (1) how generative something is, and (2) how singular it is.
The generativity of a phenomena is assessed on a scale from entirely “top-down” to entirely “bottom-up.” The range of singularity runs from “hierarchy” to “polyarchy.” This is captured in the following chart from the article:
Professor Zittrain uses precise (sometimes unconventional) definitions of these terms:
- Top-down: systems in which “there is a separation between those who make the rules and those who live under them . . . .”
- Bottom-up: systems where the rules can come from any person without separation between the people who make the rules and people who live under them.
- Hierarchy: a system in which "gatekeepers control the allocation of attention and resources to an idea."
- Note: to see how Professor Zittrain's definition of hierarchy might differ from the lay person understanding, see Wikipedia.
- Polyarchy: being able to choose between multiple regimes or systems and pursue ideas independently.
For more on this system, see The Future of the Internet and How to Stop It, chapter 4.
This section will summarize the proposals of various cyber security authors. The next section will attempt to map these proposals onto Professor Zittrain's framework.
Professor Zittrain begins his forthcoming article, A Mutual Aid Treaty for the Internet*, by describing mutual aid theory broadly and applying it to individuals on the Internet. By taking mutually beneficial, reciprocal actions, individual Internet participants can deal with real problems more efficiently.
This mutual aid framework is then extended to the World Wide Web. To ensure that cyber attacks cannot take down a website, Professor Zittrain proposes “Mirror As You Link.” This proposal takes the following form:
- 1. You visit a website.
- 2. The website appears on your computer.
- 3. As the site loads, your computer follows any links on the page and makes a local copy of these pages.
- 4. If a link no longer works, you can ask the linking site “to show you its best rendition of what you’re missing at the linked site.”
This system would require a change in the code, modifying the way Web servers work. Because Microsoft and Apache control 80% of the web server market, however, this would not be difficult. Additionally, if someone didn’t want their website to participate in Mirror As You Link, they could choose to block your computer from making a local copy.
-*This piece isn't currently available on the Internet. For a brief summary of these arguments see Professor Zittrain's New York Times piece on the subject, What Websites Can Do.
There are two relevant pieces by Jack Goldsmith in which he explores his thoughts on cyber security: the book he coauthored with Tim Wu, Who Controls The Internet?: Illusions of a Borderless World, and a recent article published in The New Republic titled The New Vulnerability.
Who Controls the Internet
Globalization has diminished the importance of borders, territory and locations, and has undermined the role of nation state's governments as the central institution for the governance and regulation of human affairs. The Internet has been seen as the catalyst of globalization and therefore it is essential in re-assessing if, and how, the role of governments has changed. Goldsmith and Wu conclude that physical coercion by government, which is a feature of traditional legal systems, has not been affected by the Internet and by globalization and remains today more important than expected. A number of examples gives evidence of this allegation: from the actions taken by Chinese government against dissidents, to the softer approach taken by western governments in inducing ISP to filter offensive communications and fighting P2P file sharing.
- The role of governments
- Goldsmith and Wu contend that governmental powers around the globe are striving to shape the architecture of the Internet through the use of their coercive power. This is leading to the de facto establishment of different local networks, more or less far from the open, free and worldwide Internet we have seen so far.
- According to this thesis, the openness of the Internet is not an inherent feature of the architecture, but rather a contingency due to the governmental coercion model that has prevailed so far. The differences between models for controlling the Internet would lead to a new technological cold war, where each side would push its own model for architecting the Internet, with the result of transforming the Internet into a collection of nation-state networks, separate from each other for many purposes.
- The role of communities
- In spite of the prominent role that governments still have on the Internet, Goldsmith and Wu suggest that private self-governing communities can still be an alternative to traditional government.
- At the same time, they suggest that this alternative governance model based on social norms, morality and the market cannot survive without an “underlying system of territorial government and physical coercion”. ICANN is brought as an example of this: a self-governance model based on technology and technocracy has managed to emerge and survive on the basis of the guarantees provided by the US government.
- In this context of nation-states networks, the book still calls for a global solution to cybercrime, a solution that would establish international legal instruments prohibiting computer invasion and disruption and set standards for inter-governmental cooperation.
- However, the authors also points at the inefficacy of a traditional international treaty in tackling cyber threats. The one example currently in place, for instance, the Council of Europe's Cybercrime Convention, has only been implemented by a scarce number of states and the response mechanisms set forth therein are deemed to be inappropriate.
- Cybercrime: an architectural solution
- The conclusion reached by Goldsmith and Wu is that the future of the Internet's security is not likely to rest on a traditional international treaty, but rather on an architectural solution.
- A “global law”, it is argued, already exists and it is the domain name system managed by ICANN. ICANN has been portrayed by the US as a form of bottom-up governance, serving and drawing inputs from the Internet “community” in the spirit of self-regulation.
- It is also pointed out that along the years the US has abandoned the rhetoric about a self-governed ICANN and has asserted that the control over ICANN will not be relinquished. While Goldsmith and Wu do not take a position on the outcome of the battle over control of ICANN, they stress that, as a matter of fact, the actors of such battle are nation-states rather than Internet communities and private companies.
The New Vulnerability
In a recent article published in The New Republic, Goldsmith takes a stand on Clarke's book Cyber War: The Next Threat to National Security and What to Do About It". The main areas of criticism in Clarke's approach indicated by Goldsmith are the following:
- Excessive focus on cyber war
- The terrorism threat is underestimated
- Greatest cyber threats come instead from espionage and theft
- Private actors are becoming more dangerous and sophisticated
- Potentiality of enormous economic damages
On the other hand, Goldsmith identifies several distinct difficulties that the US faces in tackling the new cyber threats:
- Companies underinvest in cyber safety: private profit vs. larger national interest
- Government fails to regulate software quality and service providers to avoid raising the costs of Internet access
- US skepticism in extensive Government action prevents a governmental involvement in defending private computer networks
In his article, Cyber Power, Joseph Nye argues that barriers to entry into the cyber domain are so low that non-state actors and small states can play significant roles at low levels of cost. He points to three characteristics of cyber warfare, which distinguishes it from other kinds of traditional warfare:
- 1. High number of players
- 2. Ease of entry
- 3. Opportunity for concealment
Each actor in the cyber domain has, according to Nye, specific powers and different sets of vulnerabilities, as shown in this chart from Nye's article:
Providing security is a classic function of government according to Nye, and increasing insecurity is believed to lead to an increased role of government in cyberspace. Nye indicates four major threats that should lead in principle to different solutions:
- 1. Economic espionage
- 2. Crime
- 3. Cyber war
- 4. Cyber terrorism
According to Nye, currently the highest costs come from the first two categories (economic espionage and crime), i.e., crimes committed by individual and small groups targeting civilian infrastructures and organizations. However, Nye envisages a change in the upcoming future, with cyberwar and cyber terrorism gaining importance.
- Nye's proposals
- can be managed through inter-state deterrence, along with offensive capabilities to be used in the event that deterrence fails.
- can be regulated in the medium/long term through evolving norms of warfare comparable to the ones developed in relation to traditional warfare, such as proportionality.
- Cyber terrorism:
- is harder to contrast.
- Insofar as the attacks are directed against private infrastructures and organization, the threat can be dealt by incentivizing private actors, particularly owners of strategic infrastructure, to join secure systems rather than relying on the open Internet.
- International treaties:
- Large scale formal treaties regulating cyberspace, according to Nye, are unlikely at the moment.
- While governments will end up remaining the stronger actors, cyberspace is likely to increase the diffusion of power to non-state actors.
In his article, Defending a New Domain, The Pentagon Strategy, William Lynn starts from the assumption that the US government's digital infrastructure gives the US critical advantages over other countries. On the other hand, reliance on computer infrastructures exposes the US to disruptive attacks. The strategy adopted by the Pentagon, according to Lynn, must be based on the peculiar features of threats in cyberspace. In fact, the distinctive characteristics of cyberspace have led the Pentagon to recognize it as a new domain of warfare, as critical to military operations as other more traditional domain like air, space and land.
- Government role
- Cyber warfare is asymmetric. Cyber weapons can be obtained at a relatively low cost, with high potentiality for disruptive results. This leads to ineffectiveness of a traditional deterrence model based on the acquisition of offensive capabilities against potential attackers.
- Lynn focuses instead on “active defense” mechanisms, capable of anticipating intrusion and attacks. This should be implemented through the new unified Cyber Command.
- Private sector and international level
- Lynn recognizes that any plans aimed at defending military networks would be ineffective if civilian infrastructures are not secured against potential attacks, which could also be a target in military conflicts.
- In order to achieve the goal of enhanced security the Pentagon should further explore how major private companies can help the public sector in tackling cyber threats. Additionally, the US should also find ways to exploit the private sector's innovative capacity in information technology, especially since a dramatic importance in the cyber defense is predicated on the human factor, namely the availability of highly trained human resources. The dynamism and fast development capabilities of the private sector are also taken by Lynn as an example.
- In addition to this internal connection between military and civilian infrastructures, Lynn also points out that any efforts made by the US must take into account allied countries in order to cooperate in the monitor of computer networks intrusions.
“Sabotaged circuits cannot be patched; they are the ultimate sleeper cell.”
General Clark's article, Securing the Information Highway, focuses on the problem of compromised hardware -- usually computer chips with built-in rogue transistors that allow another party to gain control of a system. Clark believes this is the greatest threat for cyber security.
- Software attacks, on the other hand, “are generally detectable, are mostly curable, and, until now, have been largely containable through the use of software patches."
- Two challenges with enhancing hardware security:
- 1. Ensuring authenticity.
- 2. Detecting malevolent function inside the device.
- Other problems that are making things worse:
- 1. Americans have a false sense of security.
- 2. We’re not doing anything – the longer we wait, the better adversaries will get.
We need to learn from the open-source community and create security standards that allow us to quickly discover and correct security flaws.
- We “need to endow U.S. networks, software, and even hardware with a digital immune system—one that is openly described and freely discussed.”
- Clark proposes a two-step approach:
- 1. Diversify the digital infrastructure.
- We need more diversity in both hardware and software (operating systems) to make it harder to attack large sections at once.
- 2. Secure the supply chain for hardware.
- Embed compact authentication codes directly into devices.
- Anti-tamper safeguards after devices are produced
- 1. Diversify the digital infrastructure.
- Note that this doesn’t mean we have to manufacture everything here – that’s a practical impossibility given the demand. We just need to ensure foreign-made products are “authentic and secure.”
In its report for the Council on Foreign Relations, Internet Governance in an Age of Cyber Insecurity, Knake examines the current position of the United States in dealing with cyber-security at the international level and the challenges faced by the international community.
Knake points out that while the US have refused to cooperate at the international level on a new governance for the Internet, China, Russia and other non democratic regimes have been organizing a united front to promote a new model for the Internet, tightly controlled by states. According to Knake, a free and open Internet is in the US’ national interest and therefore the government should actively fight the threats arising from cyber crime, espionage and warfare while at the same time preserving the democratic infrastructure of the web.
In order to reach this goal Knake indicates three basic principles, to be implemented through a three-part agenda the US should implement:
- 1. Take a networked and distributed approach
- 2. Establish accountability of states for their actions, the actions of their citizens, and their systems
- 3. Start cleaning up the US national network
The above three principles should be implemented through the following three-part agenda:
- 1. Create a stronger sets of international regimes to fight crime in cyberspace
- Knake appears to be a supporter of a hands-off approach to the Internet. He points out that so far the US has only maintained control of one necessary infrastructure component (the DNS, Domain Name System) which needs active management, but otherwise has taken the position that the role of the government should be limited.
- According to Knake this approach should be adapted at changing times and increased cyber threats at the international level. New times demand the development of new international instruments to fight cyber crime and implement real-time mechanisms for international cooperation in fighting and investigating cross-border attacks.
- Russia has been pushing since 1998 for a UN treaty to address conflicts in cyberspace creating a centralized international body to tackle cyber security issues. NYT
- Knake, however, opposes a state-centric intergovernmental organization in that contrary to US interests, but rather supports a cooperative solution involving non-governmental organizations and the private sector in the development of new norms and the implementation of a more secure infrastructure.
- In certain areas, however, governmental intervention is the only practicable solution, where decentralized and inclusive approach does not work. Cyber crime (and relating problems of investigating, apprehending and prosecuting cyber criminals) is one of these areas. Council of Europe's convention on cybercrime helped in establishing laws to criminalize computer crimes and a mechanism for cross-border cooperation. However, according to Knake, it did not lead to a reduction of cybercrime. Further, such convention only envisages bilateral and prosecutorial mechanisms, ineffective in preventing attacks or tackling an attack when it occurs.
- Knake suggested the creation of national level criminal laws and development of less formal mechanisms of cooperation through a “light” intergovernmental body. Knake's goal is a stronger international governance of the Internet, but “tailored to specifically address a narrow set of security concerns surrounding crime and warfare”. An approach clearly opposed to Russia's and China's “information security”.
- 2. Constrain state actors in cyberspace
- In order to solve the attribution problem (i.e., the extreme difficulties in tracking the origin of attacks in the cyberspace) Knake suggests that US should commit to pursue criminal prosecution of citizens engaging in hacktivism against foreign countries.
- Foreign states should do the same, and failure to cooperate in doing so should be deemed as a sign of complicity. States should be accountable for their actions, as well as those of their citizens and their systems.
- In the past decade US has been focusing on cybercrime and refused to enter into negotiations on warfare and espionage.
- Knake says US should now overthrow the perception that US wants to maintain exploitation and attack capabilities at a level above other states. While keeping such capabilities is in the US interest, giving away such perception may be detrimental, and refusing in particular to enter into negotiations on state limitations to cyber warfare attracts critics.
- Knake suggests a renewed engagement of the US, but not as set forth in current treaty options. The Russian proposal, for instance, would commit signatories to abstain from developing offensive cyber capabilities while not providing any mechanism for the verification of their compliance. His proposed solution would be not to focus on limiting state actors offensive capabilities, bur rather limiting their penetration into civilian infrastructures (power grids, financial infrastructures).
- 3. Secure the Internet's underlying technology
- Knake suggests that it is now time to shift the focus of international and local attention from coordination and interoperability to security.
- The development of more secure technical protocols is much needed, Knake argues, and the government should provide guidance in the technical area.
- The private sector should be involved in a centralized forum established by the government to coordinate the Internet governance agenda, including big US corporations such as Microsoft and Symantec.
Mapping Onto the Four Quadrants
Four Quadrants: Elaborated
Professor Zittrain mapped existing political philosophies onto his four quadrants. The result was presented in his article:
We have taken this framework and tried to determine which Internet groups generally occupy each quadrant.
- 1. We believe that the first quadrant is the traditional domain of governments. Governments promulgate and enforce rules, and generally offer few or no alternatives.
- 2. The second quadrant is occupied by corporations, who act similarly to governments but offer the choice between numerous systems.
- 3. Hackers are the best example of the third quadrant. These groups create their own hacker ethics from the bottom-up, and encourage polyarchy.
- 4. The fourth quadrant is occupied by "Netizens" -- active users of Internet sites like Wikipedia. These groups typically promulgate their own rules, but offer a more hierarchical structure.
Mapping the Proposals
Why the mapping?
The four quadrants can be a useful tool to dissect each of the proposal examined above: placing each proposal on a map allows the reader to understand in detail the interests at stake, the actors involved and the consequences of each approach. The mapping of the proposals is also helpful in understanding where each proposal actually stands, as opposed as where it purports to stand. In this respect, we argue that the perception of a proposal may determine how much support it can gain, but such perception does not necessarily capture all the implications of that proposal.
Where We Think They Go
Consider Professor Zittrain's article: at a first glance the Mirror As You Link approach would clearly place his proposal in the fourth quadrant, due to the communitarian and distributed nature of the solution. However, it is also suggested that the practical implementation should not occur through an action by users, but through a basic technological change adopted by two major servers manufacturers, Microsoft and Apache (an "architectural" modification). Does this way of implementation place this proposal in the second quadrant along with other solutions enacted by corporate actors? Would an article called the Second Quadrant be perceived in the same way and gain the same support?
Clarke's solution for increasing the security of the US national network encompasses a nation-wide scanning and sanitization of all the communications entering, or passing through the US computer infrastructure. This solution appears to be a typical form of government action that would place this proposal in the first quadrant. On the other hand, Clarke argues that the proposed security barrier should not be managed by governmental authorities themselves, but rather by private actors entrusted to do so by the government. How the primary role of private corporations in the implementation of this solution would affect its position on the four quadrants? Should it be moved to the second quadrant? Why would the privacy concerns expressed by Clarke be better assessed by a corporate solution?
If we take into consideration the proposed solutions (Clarke's and others) at the international level, it is even harder to identify their position on the map, and how their approach should be defined. When confronted with the plurality of state actors on the international scene, even proposals that focus on governmental intervention may be easily shifted to other parts of the map due to the very nature of intergovernmental interaction.
- Quadrant 1
- Nye: Nye's proposal appears to fall squarely in the first quadrant. He believes governmental authorities to be the most important actors in the cyber domain, and while he calls for the enhancement of private sector infrastructures' security, he seems to suggest that it should be done through government intervention. Furthermore, Nye do not believe that an international solution would be easily found.
- Quadrant 2
- Wesley Clark: Clark's proposal clearly falls in the second quadrant. His call to diversify the digital infrastructure is a polyarchical solution. Additionally, Clark intends for the government to promulgate all of these rules, which is a top-down solution.
- Quadrant 3
- Quadrant 4
Quadrant 1 or 4?
- Knake: At a first sight Knake's set of proposals appears to fall within the fourth quadrant. He is in fact proposing a Networked and distributed approach, to be implemented through the active involvement of a wide range of participants from the technical community, the private sector, as well as users and consumer groups, to shape policy and avoid state-centric processes. Not a single forum, at either national or international level, bur rather a range of forums.
- At a deeper reading of Knake's arguments, however, it appears more clear that - in his mind - the US should nurture and indirectly control his proposed "light intergovernmental body". When Knake urges the US to be involved in international negotiations concerning the fight of cyber crime, he does so to avoid a "perception" that would eventually turn out to be detrimental to the US. Even private actors, such as Microsoft and Symantec, would be captured in the governmental sphere, by being made aware of the goals of the US government and actively help in achieving such goals.
- Goldsmith: His approach appears to rely heavily on communitarian, self-governed mechanisms to face the new cyber threats, which would place it in the fourth quadrant. However, Goldsmith himself acknowledges that governmental intervention is to some extent necessary to support and guarantee the efficacy of community organizations.
Quadrant 2 or 4?
- Mirror As You Link: Professor Zittrain's proposal allows Internet users to download a website from different servers, which seems to be a polyarchical solution. Additionally, this system needs to be adopted and maintained by web server vendors, which are top-down institutions. This seems to indicate that Mirror As You Link is a first quadrant solution. It could be argued, however, that this system also falls in the fourth quadrant. Mirror As You Link could be adopted in such a way that rules are agreed upon by the Internet users themselves, and it's unclear whether there would be an ability for users to choose between multiple linking regimes.
Quadrant 1 or 2?
- Lynn: His approach appears prima facie based on strong government intervention, which would place his proposal in the first quadrant. However, Lynn also stresses the importance of vital energies that can be found in the private sector, and in particular the need to actively involve in the prevention of cyber threats private actors having technological know-how and capabilities.
