About the Event: In conversation with Philip Taubman, General Hayden will discuss intelligence and cybersecurity challenges the United States faces in combatting terrorism, dealing with North Korea, Iran and Russia, and will assess President Trump’s relations with the U.S. intelligence community. 

About the Speaker: General Michael Hayden is a retired four-star general who served as director of the Central Intelligence Agency and the National Security Agency when the course of world events was changing at a rapid rate. As head of the country’s premier intelligence agencies, he was on the frontline of global change, the war on terrorism and the growing cyber challenge. He understands the dangers, risks, and potential rewards of the political, economic, and security situations facing us. General Hayden dissects political situations in hot spots around the world, analyzing the tumultuous global environment and what it all means for Americans and America’s interests. He speaks on the delicate balance between liberty and security in intelligence work, as well the potential benefits and dangers associated with the cyber domain. As the former head of two multi-billion dollar enterprises, he can also address the challenges of managing complex organizations in times of stress and risk, and the need to develop effective internal and external communications.

In addition to leading CIA and NSA, General Hayden was the country’s first principal deputy director of national intelligence and the highest-ranking military intelligence officer in the country.  In all of these jobs, he worked to put a human face on American intelligence, explaining to the American people the role of espionage in protecting both American security and American liberty.  Hayden also served as commander of the Air Intelligence Agency and Director of the Joint Command and Control Warfare Center and served in senior staff positions at the Pentagon, at U.S. European Command, at the National Security Council, and the U.S. Embassy in Bulgaria. He was also the deputy chief of staff for the United Nations Command and U.S. Forces in South Korea.

Hayden has been a frequent expert and commentator on major news outlets and in top publications, valued for his expertise on intelligence matters like cyber security, government surveillance, geopolitics, and more. He was featured in the HBO documentary Manhunt, which looked at espionage through the eyes of the insiders who led the secret war against Osama bin Laden, and in Showtime’s The Spymasters, a detailed look at the directors of the Central Intelligence Agency.

Hayden is currently a principal at the Chertoff Group and a distinguished visiting professor at the George Mason University Schar School of Policy and Government. He is on the board of directors of Motorola Solutions and serves on a variety of other boards and consultancies. In 2013, the Intelligence and National Security Alliance (INSA) awarded Hayden the 29th annual William Oliver Baker Award.  General Hayden is also the first recipient of the Helms Award presented by the CIA Officers’ Memorial Foundation.  In 2014 he was the inaugural Humanitas visiting professor in intelligence studies at Oxford University in the United Kingdom.  His recent memoir, Playing to the Edge: American Intelligence in the Age of Terror, has been a New York Times best-seller and was recently selected as one of the 100 most notable books of 2016.

About the event: In his talk Toomas Hendrik Ilves will discuss how various digital tools have been used in democracies in Europe and the US in an attempt to disrupt and affect elections outcomes. These are new approaches, meant if not to alter electoral outcomes then at least to sow discord and seem in some instances to have been successful. Methods used include hacking into political parties' servers and “doxxing” embarrassing hacked materials; disseminating via “bots” false stories that have occasionally gone viral; as well highly granular big data analyses to target voters with ads specifically tailored to their profiles as culled from social media.

These methods and tactics have been employed in the U.S, French, and Dutch elections; cyber-break-ins into the Bundestag and German political think tanks suggest they will play a role in the upcoming German parliamentary elections. Perpetrated by an authoritarian government, they are asymmetric: without a free media environment they are immune to such tacts even if democracies were to even try to respond in kind. What democracies have experienced in the past several years will force them to adapt to a new environment with the realization that there are many ways for an adversary to change a nations policies.

About the Speaker: Toomas Hendrik Ilves was born on December 26, 1953, to an Estonian family living in Stockholm, Sweden. He was educated in the United States, receiving a degree from Columbia University in 1976 and a master's degree in psychology from the University of Pennsylvania in 1978.

In 1984 he moved to Munich, Germany, to work at the office of Radio Free Europe, first as a researcher and foreign policy analyst and later as the head of the Estonian Desk.

From 1993 to 1996 Ilves served in Washington as the ambassador of the Republic of Estonia to the United States and Canada. During this time, he launched the Tiger Leap Initiative to computerize and connect all Estonian schools online with Education Minister Jaak Aaviksoo. He then served as minister of foreign affairs from 1996 to 1998. After a brief period as chairman of the North Atlantic Institute in 1998, he was again appointed minister of foreign affairs, serving until 2002.

From 2002 to 2004, Ilves was a member of the Estonian Parliament and in 2004 he was elected a member of the European Parliament, where he was vice-president of the Foreign Affairs Committee. As a MEP, he initiated the Baltic Sea Strategy that was later implemented as official regional policy of the European Union.

Ilves was elected president of the Republic of Estonia in 2006. He was re-elected for a second term in office in 2011.

During his presidency, Ilves has been appointed to serve in several high positions in the field of ICT in the European Union. He served as chairman of the EU Task Force on eHealth from 2011 to 2012 and was chairman of the European Cloud Partnership Steering Board at the invitation of the European Commission from 2012 to 2014. In 2013 he chaired the High-Level Panel on Global Internet Cooperation and Governance Mechanisms convened by ICANN. From 2014 to 2015 Ilves was the co-chair of the advisory panel of the World Bank's World Development Report 2016 "Digital Dividends" and was also the chair of World Economic Forum's Global Agenda Council on Cyber Security beginning in June 2014.

Starting from 2016, Ilves co-chairs The World Economic Forum working group The Global Futures Council on Blockchain Technology. In 2017 he joined Stanford University as a Bernard and Susan Liautaud Distinguished Visiting Fellow at the Center for International Security and Cooperation in the Freeman Spogli Institute for International Studies.

President Ilves has published many essays and articles in Estonian and English on numerous topics ranging from Estonian language, history, and literature to global foreign and security policy and cyber security. His books include essay collections in Estonian, Finnish, Latvian, Hungarian, and Russian.

His international awards and honorary degrees include Knight of Freedom Award by the Casimir Pulaski Foundation (2016), the Aspen Prague Award by the Aspen Institute (2015), the Freedom Award by the Atlantic Council (2014) and the NDI Democracy Award by the National Democratic Institute (2013). His Honorary Degrees include an Honorary Degree from St. Olaf College, US (2014), an Honorary Degree from the John Paul II Catholic University of Lublin, Poland (2010), and an Honorary Degree from Tbilisi University, Georgia (2007).

Abstract: High-security organizations around the world face devastating threats from insiders—trusted employees with access to sensitive information, facilities, and materials. From Edward Snowden to the Fort Hood shooter to the theft of nuclear materials, the threat from insiders is on the front page and at the top of the policy agenda. Insider Threats offers detailed case studies of insider disasters across a range of different types of institutions, from biological research laboratories, to nuclear power plants, to the U.S. Army. Matthew Bunn and Scott D. Sagan outline cognitive and organizational biases that lead organizations to downplay the insider threat, and they synthesize "worst practices" from these past mistakes, offering lessons that will be valuable for any organization with high security and a lot to lose.

About the Speakers: Matthew Bunn is a Professor of Practice at Harvard University's John F. Kennedy School of Government. His research interests include nuclear theft and terrorism; nuclear proliferation and measures to control it; the future of nuclear energy and its fuel cycle; and policies to promote innovation in energy technologies. Before joining the Kennedy School in January 1997, he served for three years as an adviser to the Office of Science and Technology Policy, where he played a major role in U.S. policies related to the control and disposition of weapons-usable nuclear materials in the United States and the former Soviet Union, and directed a secret study for President Clinton on security for nuclear materials in Russia.

Scott S. Sagan is the Caroline S.G. Munro Professor of Political Science, the Mimi and Peter Haas University Fellow in Undergraduate Education, and Senior Fellow at the Center for International Security and Cooperation and the Freeman Spogli Institute at Stanford University. He also serves as Project Chair for the American Academy of Arts and Sciences’ Initiative on New Dilemmas in Ethics, Technology, and War. Before joining the Stanford faculty, Sagan was a lecturer in the Department of Government at Harvard University. From 1984 to 1985, he served as special assistant to the director of the Organization of the Joint Chiefs of Staff in the Pentagon. Sagan has also served as a consultant to the office of the Secretary of Defense and at the Sandia National Laboratory and the Los Alamos National Laboratory. 

Amy Zegart is is co-director of CISAC and Professor of Political Science, by courtesy. She is also the Davies Family Senior Fellow at the Hoover Institution. 

Before coming to Stanford in 2011, Zegart served as professor of public policy at UCLA’s Luskin School of Public Affairs and as a fellow at the Burkle Center for International Relations. Her research examines the organization of American national security agencies and their effectiveness. She is the author of two award-winning books. Flawed by Design, which chronicles the development of the Central Intelligence Agency, Joint Chiefs of Staff, and National Security Council, won the highest national dissertation award in political science. Spying Blind, which examines why American intelligence agencies failed to adapt to the terrorist threat before 9/11, won the National Academy of Public Administration’s Brownlow Book Award. She has also published in International Security, Political Science Quarterly, and other leading academic journals. She serves on the editorial boards of Terrorism and Political Violence and Intelligence and National Security.

Safety-critical system domains such as critical infrastructures, aerospace, automotive, and industrial manufacturing and control are becoming increasingly dependent on the use of distributed systems to achieve their functionality. These distributed systems can contain many complex interactions among their constituent components. Despite extensive testing and verification of individual components, security vulnerabilities resulting from unintended and unforeseen component interactions (so-called implicit interactions) often remain undetected and can have an impact on the safety, security, and reliability of a system. This paper presents an approach for identifying and analyzing the existence and severity of implicit interactions in distributed systems. The approach is based on the modeling framework known as Communicating Concurrent Kleene Algebra (C²KA). Experimental results confirm that this approach can successfully identify and analyze dependencies in system designs that would otherwise be very hard to find. More broadly, the methods presented in this paper can help address the growing need for rigorous and practical methods and techniques for assuring the safe, secure, and reliable operation of distributed systems in critical domains.

Abstract: Microsoft President Brad Smith recently analogized Microsoft to a “Digital Switzerland.” This moniker captures the role that U.S. technology companies have increasingly taken on with respect to cybersecurity and privacy: they are acting like states and running their own foreign policies, and they are setting themselves as neutrals with respect to existing national authorities, including the United States. U.S. tech companies are not the first super-empowered private companies, but they have numerous features that set them apart from prior private powers like the Dutch East India Company or more recent examples like ExxonMobil. This article first provides an account of how the relationship between U.S. tech companies and governments has evolved over time. By breaking down the “Digital Switzerland” idea, the article then explores the extent to which and how the companies differ from the powerful private interests of earlier eras, and it concludes by analyzing the implications of the companies’ role for governance and for individuals going forward.

Abstract: Recently, Twitter, Netflix, Spotify, Airbnb, Reddit, Etsy, SoundCloud, and The New York Times were knocked out by a botnet driven by the Mirai malware. Mirai is a contemporary case of a more general phenomenon: the illegitimate appropriation of online resources for prestige, economic, and/or political gain. Historically participants in the anti-abuse regime have used reputation indicators to characterize subsets of this illegitimate activity as abuse: any traffic---spam, malware communications, DDOS traffic---that is not explicitly consensual, is abusive. Participants in this regime use decentralized, transnational monitoring to aggregate and vet credible reputation indicators, then redistribute these indicators to participants enforcing anti-abuse norms. This work explains how these reputation indicators have functioned over the course of their evolution within this regime, from products of supposedly “vigilante blacklists” into credible mechanisms based on graduated sanction as a remediative signaling mechanism rather than a punitive sanction. Returning to Mirai, this work concludes by evaluating the potential for this regime to tackle contemporary IoT security challenges. In particular, can the anti-abuse regime discipline a market projected to grow from $900M in 2015 to $3.7B in 2020, or will it need help from conventional authorities?

About the Speaker: Jesse is the 2016-2017 Cybersecurity Fellow at the Center for International Security and Cooperation and holds a PhD in Technology, Management, and Policy from MIT.  Jesse focuses on understanding the institutions and political economy of Internet operations vis a vis conventional modes of domestic and inter-state governance mechanisms. This work includes studies on infrastructure resource management and policy, infrastructure security, credible knowledge assessment, and operational epistemic communities’ role informing public policy. Jesse’s dissertation evaluates the common resource management institutions that sustain the integrity and security of the Internet’s numbers and routing system. The dissertation documents how the roles of these institutions, comprising diverse transnational operator communities, managing the complex of physical and information resources supporting the integrity of global Internet connectivity. Concluding analyses narrow the focus from operational authority to the character of political authority in these communities, rooted in the family of consensus processes used to adapt resource policy and institutions apace with Internet growth and development.  Jesse is currently working on a number of papers from his dissertation: reputation and security in the numbers and routing system, contrasting consensus as a decision-making process with conventional mechanisms for credible knowledge assessment, and the challenges in comity between substantive-purposive authority in operational institutions with governments’ conventional, formal-legalistic modes of authority. Ongoing work is developing a theory of epistemic constructivism and case work on developing joint capabilities between operational security regimes and law enforcement/national security actors.

Modern distributed systems and networks, like those found in cyber-physical system domains such as critical infrastructures, contain many complex interactions among their constituent software and/or hardware components. Despite extensive testing of individual components, security vulnerabilities resulting from unintended and unforeseen component interactions (so-called implicit interactions) often remain undetected. This paper presents a method for identifying the existence of implicit interactions in designs of distributed cyber-physical systems using the algebraic modeling framework known as Communicating Concurrent Kleene Algebra (C²KA). Experimental results verifying the applicability of C²KA for identifying dependencies in system designs that would otherwise be very hard to find are also presented. More broadly, this research aims to advance the specification, design, and implementation of distributed cyber-physical systems with improved cybersecurity assurance by providing a new way of thinking about the problem of implicit interactions through the application of formal methods.
