Choucri, Nazli, Agarwal, Gaurav.  2022.  Analytics for Cybersecurity Policy of Cyber-Physical Systems. 2022 IEEE International Symposium on Technologies for Homeland Security (HST). :1—7.
Guidelines, directives, and policy statements are usually presented in “linear” text form - word after word, page after page. However necessary, this practice impedes full understanding, obscures feedback dynamics, hides mutual dependencies and cascading effects and the like-even when augmented with tables and diagrams. The net result is often a checklist response as an end in itself. All this creates barriers to intended realization of guidelines and undermines potential effectiveness. We present a solution strategy using text as “data”, transforming text into a structured model, and generate network views of the text(s), that we then can use for vulnerability mapping, risk assessments and note control point analysis. For proof of concept we draw on NIST conceptual model and analysis of guidelines for smart grid cybersecurity, more than 600 pages of text.

Policy documents are usually written in text form—word after word, sentence after sentence, page after page, section after section, chapter after chapter—which often masks some of their most critical features. The text form cannot easily show interconnections among elements, identify the relative salience of issues, or represent feedback dynamics, for example. These are “hidden” features that are difficult to situate. This paper presents a computational analysis of Tallinn Manual 2.0 on the International Law Applicable to Cyber Operations, a seminal work in International Law. Tallinn Manual 2.0 is a seminal document for many reasons, including but not limited to, its (a) authoritative focus on cyber operations, (b) foundation in the fundamental legal principles of the international order and (c) direct relevance to theory, practice, and policy in international relations. The results identify the overwhelming dominance of specific Rules, the centrality of select Rules, the Rules with autonomous standing (that is, not connected to the rest of the corpus), and highlight different aspects of Tallinn Manual 2.0, notably situating authority, security of information -- the feedback structure that keeps the pieces together. This study serves as a “proof of concept” for the use of computational logics to enhance our understanding of policy documents.
Choucri, Nazli, Fairman, Lauren, Agarwal, Gaurav.  2021.  CyberIRWorld@MIT: Exploration & Innovation in International Relations. MIT Political Science Network. :1-41.
This paper presents a brief introduction to Cyber-IR@MIT—a dynamic, interactive knowledge and networking system focused on the evolving, diverse, and complex interconnections of cyberspace and international relations. The goal is to highlight key theoretical, substantive, empirical and networking issues. Cyber-IR@MIT is anchored in a multidimensional ontology. It was initially framed as an experiment during the MIT-Harvard collaboration on Explorations in Cyber International Relations (MIT, 2009-2014) to serve as a forum for quality-controlled content and materials generated throughout the research project. The vision for Cyber-IR@MIT is shaped by the research for Cyberpolitics in International Relations, a book written by Nazli Choucri and published by MIT Press in 2012. The operational approach to the knowledge system is influenced by the Global System for Sustainable Development (GSSD), developed earlier and focused on challenges of system sustainability. Cyber-IR@MIT gradually evolved into a knowledge-based system of human interactions in cyberspace and international relations, all embedded in the overarching natural system. The method consists of differentiating among the various facets of human activity in (i) cyberspace, (ii) international relations, and (iii) the intersection of the cyber and “real.” It includes problems created by humans and solution strategies, as well as enabling functions and capabilities, on the one hand, and impediments to behavior and associated barriers, on the other. See https://cyberir.mit.edu for functions. The value of this initiative lies in its conceptual foundations and method of knowledge representation – embedded in an interactive system for knowledge submission, with f search and retrieval functions.

Almost everyone recognizes the emergence of a new challenge in the cyber domain, namely increased threats to the security of the Internet and its various uses. Seldom does a day go by without dire reports and hair raising narratives about unauthorized intrusions, access to content, or damage to systems, or operations. And, of course, a close correlate is the loss of value. An entire industry is around threats to cyber security, prompting technological innovations and operational strategies that promise to prevent damage and destruction. This paper is a collection chapters entitled 1) "Cybersecurity – Problems, Premises, Perspectives," 2) "An Abbreviated Technical Perspective on Cybersecurity," 3) "The Conceptual Underpinning of Cyber Security Studies" 4) "Cyberspace as the Domain of Content," 5) "The Conceptual Underpinning of Cyber Security Studies," 6) "China’s Perspective on Cyber Security," 7) "Pursuing Deterrence Internationally in Cyberspace," 8) "Is Deterrence Possible in Cyber Warfare?" and 9) "A Theoretical Framework for Analyzing Interactions between Contemporary Transnational Activism and Digital Communication."

Abstract In international relations, the traditional approaches to theory and research, practice, and policy were derived from experiences in the 19th and 20th centuries. But cyberspace, shaped by human ingenuity, is a venue for social interaction, an environment for social communication, and an enabler of new mechanisms for power and leverage. Cyberspace creates new condition — problems and opportunities — for which there are no clear precedents in human history. Already we recognize new patterns of conflict and contention, and concepts such as cyberwar, cybersecurity, and cyberattack are in circulation, buttressed by considerable evidence of cyber espionage and cybercrime. The research problem is this: distinct features of cyberspace — such as time, scope, space, permeation, ubiquity, participation and attribution — challenge traditional modes of inquiry in international relations and limit their utility. The interdisciplinary MIT-Harvard ECIR research project explores various facets of cyber international relations, including its implications for power and politics, conflict and war. Our primary mission and principal goal is to increase the capacity of the nation to address the policy challenges of the cyber domain. Our research is intended to influence today’s policy makers with the best thinking about issues and opportunities, and to train tomorrow’s policy makers to be effective in understanding choice and consequence in cyber matters. Accordingly, the ECIR vision is to create an integrated knowledge domain of international relations in the cyber age, that is (a) multidisciplinary, theory-driven, technically and empirically; (b) clarifies threats and opportunities in cyberspace for national security, welfare, and influence;(c) provides analytical tools for understanding and managing transformation and change; and (d) attracts and educates generations of researchers, scholars, and analysts for international relations in the new cyber age.

Governing cybersecurity risks from digital trade is a growing responsibility for governments and corporations. This study develops a systematic framework to delineate and analyze the strategies that governments and corporations take to address cybersecurity risks from digital trade. It maps out the current landscape based on a collection of 75 cases where governments and corporations interact to govern transnational cybersecurity risks. This study reveals that: first, governing cybersecurity risks from digital trade is a global issue whereby most governments implement policies with concerning that the cybersecurity risks embedded within purchasing transnational digital products can influence their domestic political and societal systems. Second, governments dominates the governance interactions by implementing trade policies whereas corporations simply comply. Corporations do, however, have chances to take more active roles in constructing the governance system. Third, supply chain cybersecurity risks have more significant impacts on governance mode between governments and corporations whereas concerns on different national cybersecurity risks do not. Fourth, the interactions between governments and corporations reveal the existence of loops that can amplify or reduce cybersecurity risks. This provides policy implications on transnational cybersecurity governance for policy makers and business leaders to consider their potential options and understand the global digital trade environment when cybersecurity and digital trade overlap.

The highly dynamic nature of the cyber domain demands that cyber operators are capable of rapidly evolving and adapting with exquisite timing. These forces, in turn, pressure acquisition specialists to accoutre cyber warfighters to keep pace with both cyber domain advancement and adversary progression. However, in the Department of Defense (DoD), a vigorous tug of war exists between time and risk pressures. Risk reduction is a crucial element of managing any complex enterprise and this is particularly true for the DoD and its acquisition program [1]. This risk aversion comes at significant cost, as obsolescence by risk minimization is a real phenomenon in DoD acquisition programs and significantly limits the adaptability of its operational cyber forces. Our previous research generated three recommendations for reforming policy to deliver performance at the “speed of relevance” [3]. In this paper we focus on one of the recommendations: “Manage rather than avoid risk—especially time-based risks”. While this advice can apply to many areas of human endeavor, it has elevated urgency in cyberspace. Incomplete risk metrics lead to overly conservative acquisition efforts that imperil timely procurement of advanced cyber capabilities and repel innovators. Effective cyber defense operations require acquisition risk models to be extended beyond fiscal and technical risk metrics of performance, to include risks associated with the cost of failing to meet immediate mission requirements. This paper proposes a time-shifting approach to simultaneously (a) accelerate capability delivery while maintaining traditional rigor, and (b) achieve optimal balance between fiscal, performance, and time risks.
Klemas, Thomas, Lively, Rebecca K, Choucri, Nazli.  2019.  Cyber Acquisition. The Cyber Defense Review. :103–120.
The United States of America faces great risk in the cyber domain because our adversaries are growing bolder, increasing in number, improving their capabilities, and doing so rapidly. Meanwhile, the associated technologies are evolving so quickly that progress toward hardening and securing this domain is ephemeral, as systems reach obsolescence in just a few years and revolutionary paradigm shifts, such as cloud computing and ubiquitous mobile devices, can pull the rug out from the best-laid defensive planning by introducing entirely new regimes of operations. Contemplating these facts in the context of Department of Defense (DoD) acquisitions is particularly sobering because many cyber capabilities bought within the traditional acquisition framework may be of limited usefulness by the time that they are delivered to the warfighter. Thus, it is a strategic imperative to improve DoD acquisitions pertaining to cyber capabilities. This paper proposes novel ideas and a framework for addressing these challenges.
Choucri, Nazli, Agarwal, Gaurav.  2021.  Complexity of International Law for Cyber Operations. 2021 IEEE International Symposium on Technologies for Homeland Security (HST). :1–7.
Policy documents are usually written in text form— word after word, sentence after sentence etc.—which often obscures some of their most critical features. Text cannot easily situate interconnections among elements, or identify feedback, nor reveal other embedded features. This paper presents a computational approach to International Law Applicable to Cyber Operations 2.0, Tallinn Manual, a seminal work of 600 pages at the intersection of law and cyberspace. The results identify the dominance of specific Rules, the centrality of select Rules, and Rules with autonomous standing, as well as the feedback structure that holds the system together. None of these features are evident from the text alone.
Choucri, Nazli, Agarwal, Gaurav.  2019.  Securing the Long-Chain of Cyber-Physical Global Communication Infrastructure. 2019 IEEE International Symposium on Technologies for Homeland Security (HST). :1–7.
Executive Order, May 2019 states: “...foreign adversaries are increasingly creating and exploiting vulnerabilities in information and communications technology and services ... in order to commit malicious cyber-enabled actions, including economic and industrial espionage against the United States and its people. ” [1]. This paper focuses on challenges of securing the long chain of global communication infrastructure, presents some illustrative data, and puts forth a multi-method research design for analysis of long-chain systems of information and or communications technology, infrastructure, services, ownership, providers, and networks - within a state and outside its jurisdiction - all essential for unimpeded global operations. A proof of concept for data requirements to support end-to-end integrated research is provided, along with highlights of some initial empirical analysis, with China as a case in point.
Choucri, Nazli, Agarwal, Gaurav.  2017.  The Theory of Lateral Pressure: Highlights of Quantification and Empirical Analysis. Oxford Research Encyclopedias, Politics.
The term lateral pressure refers to any tendency (or propensity) of states, firms, and other entities to expand their activities and exert influence and control beyond their established boundaries, whether for economic, political, military, scientific, religious, or other purposes. Framed by Robert C. North and Nazli Choucri, the theory addresses the sources and consequences of such a tendency. This chapter presents the core features—assumptions, logic, core variables, and dynamics—and summarizes the quantitative work undertaken to date. Some aspects of the theory analysis are more readily quantifiable than others. Some are consistent with conventional theory in international relations. Others are based on insights and evidence from other areas of knowledge, thus departing from tradition in potentially significant ways. Initially applied to the causes of war, the theory focuses on the question of: Who does what, when, how, and with what consequences? The causal logic in lateral pressure theory runs from the internal drivers (i.e., the master variables that shape the profiles of states) through the intervening variables (i.e., aggregated and articulated demands given prevailing capabilities), and the outcomes often generate added complexities. To the extent that states expand their activities outside territorial boundaries, driven by a wide range of capabilities and motivations, they are likely to encounter other states similarly engaged. The intersection among spheres of influence is the first step in complex dynamics that lead to hostilities, escalation, and eventually conflict and violence. The quantitative analysis of lateral pressure theory consists of six distinct phases. The first phase began with a large-scale, cross-national, multiple equation econometric investigation of the 45 years leading to World War I, followed by a system of simultaneous equations representing conflict dynamics among competing powers in the post–World War II era. The second phase is a detailed econometric analysis of Japan over the span of more than a century and two World Wars. The third phase of lateral pressure involves system dynamics modeling of growth and expansion of states from 1970s to the end of the 20th century and explores the use of fuzzy logic in this process. The fourth phase focuses on the state-based sources of anthropogenic greenhouse gases to endogenize the natural environment in the study of international relations. The fifth phase presents a detailed ontology of the driving variables shaping lateral pressure and their critical constituents in order to (a) frame their interconnections, (b) capture knowledge on sustainable development, (c) create knowledge management methods for the search, retrieval, and use of knowledge on sustainable development and (d) examine the use of visualization techniques for knowledge display and analysis. The sixth, and most recent, phase of lateral pressure theory and empirical analysis examines the new realities created by the construction of cyberspace and interactions with the traditional international order.
Choucri, Nazli, Clark, David D..  2019.  International Relations in the Cyber Age: The Co-Evolution Dilemma.
A foundational analysis of the co-evolution of the internet and international relations, examining resultant challenges for individuals, organizations, firms, and states. In our increasingly digital world, data flows define the international landscape as much as the flow of materials and people. How is cyberspace shaping international relations, and how are international relations shaping cyberspace? In this book, Nazli Choucri and David D. Clark offer a foundational analysis of the co-evolution of cyberspace (with the internet at its core) and international relations, examining resultant challenges for individuals, organizations, and states. The authors examine the pervasiveness of power and politics in the digital realm, finding that the internet is evolving much faster than the tools for regulating it. This creates a “co-evolution dilemma”—a new reality in which digital interactions have enabled weaker actors to influence or threaten stronger actors, including the traditional state powers. Choucri and Clark develop a new method for addressing control in the internet age, “control point analysis,” and apply it to a variety of situations, including major actors in the international and digital realms: the United States, China, and Google. In doing so they lay the groundwork for a new international relations theory that reflects the reality in which we live—one in which the international and digital realms are inextricably linked and evolving together.
