Spaf- ford and Prof. Mikhal J. Atallah, for their time, guidance, and invaluable comments throughout the whole span of this dissertation work. I am honored to have the op- portunity to learn from such renowned scientists and highly respected mentors. They taught me the skills that would guide me in my career for years to come. I am forever indebted to them and aspire to follow in their footsteps. I would also like to express my deepest appreciation to my committee members, Prof. Samuel Wagsta↵and Prof. Matt Bishop, for their invaluable advice and help. Without their insights and hard questions, this dissertation would not have been possible. I am also extremely grateful for my beloved wife, Asma, for her continuous encour- agement and unwavering support. She provided light when the rigors of intellectual pursuit were casting a shadow. I would not have finished this dissertation without her by my side. She has sacrificed beyond what I wished for and has done so with love. Also, I am grateful for my parents for their unwavering support and unforgettable endorsement, especially to my dearest mom. She is the pillar I stand by during hard times and I owe her my life for her constant love and encouragement. Special thanks are also due to Northrop Grumman and Saudi Arabian Cultural Mission for supporting me throughout my PhD. Finally, I take this opportunity to record my sincere thanks to all the faculty, sta↵, and friends at the Computer Sci- ence Department and CERIAS; they provided me with one of the best academic environment during my PhD. iv TABLE OF CONTENTS Page LIST OF TABLES ................................ viii LIST OF FIGURES ............................... ix ABBREVIATIONS

  • A the Hacker
    A The Hacker Madame Curie once said “En science, nous devons nous int´eresser aux choses, non aux personnes [In science, we should be interested in things, not in people].” Things, however, have since changed, and today we have to be interested not just in the facts of computer security and crime, but in the people who perpetrate these acts. Hence this discussion of hackers. Over the centuries, the term “hacker” has referred to various activities. We are familiar with usages such as “a carpenter hacking wood with an ax” and “a butcher hacking meat with a cleaver,” but it seems that the modern, computer-related form of this term originated in the many pranks and practi- cal jokes perpetrated by students at MIT in the 1960s. As an example of the many meanings assigned to this term, see [Schneier 04] which, among much other information, explains why Galileo was a hacker but Aristotle wasn’t. A hack is a person lacking talent or ability, as in a “hack writer.” Hack as a verb is used in contexts such as “hack the media,” “hack your brain,” and “hack your reputation.” Recently, it has also come to mean either a kludge, or the opposite of a kludge, as in a clever or elegant solution to a difficult problem. A hack also means a simple but often inelegant solution or technique. The following tentative definitions are quoted from the jargon file ([jargon 04], edited by Eric S. Raymond): 1. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary.

  • Surprise, Deception, Denial and Warning: Strategic Imperatives
    Surprise, Deception, Denial and Warning: Strategic Imperatives by Lani Kass and J. Phillip “Jack” London Lani Kass, Ph.D., is a Corporate Strategic Advisor at CACI International. Kass previously served as a Senior Policy Advisor to the Chairman of the Joint Chiefs of Staff. She was the first woman to serve as Professor of Military Strategy at the National War College. J. Phillip London, Ph.D., is Chairman of the Board of CACI International. A graduate of the U.S. Naval Academy, he spent 24 years on active and reserve duty. London is the recipient of numerous industry awards and serves on several boards, including the U.S. Naval Institute and CAUSE. The views presented here are the authors’ alone. This article is a tribute to the National War College’s distinguished graduates, among them Service Chiefs, Combatant Commanders, and literally hundreds of senior diplomats, warriors and statesmen. Abstract: This article frames the highly complex national security challenges of surprise, denial and deception. These ultimate asymmetric threats exploit vulnerabilities, capitalizing on hubris, complacency and self-delusion. Such actions prevent the full and accurate assessment of opponents’ capabilities and intentions, and hinder appropriate actions. The long and frequent history of surprise, denial and deception suggest that these are essentially psychological phenomena. They are effective because they challenge and exploit perceptions that fill the gap between what is known and unknown. The authors present decision superiority as the fusion of information dominance and decisive action. Technology and intelligence can enhance decision superiority by ameliorating, but not eliminating, the limits of human perception.

  • Who Watches the Watchmen? the Conflict Between National Security and Freedom of the Press
    WHO WATCHES THE WATCHMEN WATCHES WHO WHO WATCHES THE WATCHMEN WATCHES WHO I see powerful echoes of what I personally experienced as Director of NSA and CIA. I only wish I had access to this fully developed intellectual framework and the courses of action it suggests while still in government. —General Michael V. Hayden (retired) Former Director of the CIA Director of the NSA e problem of secrecy is double edged and places key institutions and values of our democracy into collision. On the one hand, our country operates under a broad consensus that secrecy is antithetical to democratic rule and can encourage a variety of political deformations. But the obvious pitfalls are not the end of the story. A long list of abuses notwithstanding, secrecy, like openness, remains an essential prerequisite of self-governance. Ross’s study is a welcome and timely addition to the small body of literature examining this important subject. —Gabriel Schoenfeld Senior Fellow, Hudson Institute Author of Necessary Secrets: National Security, the Media, and the Rule of Law (W.W. Norton, May 2010). ? ? The topic of unauthorized disclosures continues to receive significant attention at the highest levels of government. In his book, Mr. Ross does an excellent job identifying the categories of harm to the intelligence community associated NI PRESS ROSS GARY with these disclosures. A detailed framework for addressing the issue is also proposed. This book is a must read for those concerned about the implications of unauthorized disclosures to U.S. national security. —William A. Parquette Foreign Denial and Deception Committee National Intelligence Council Gary Ross has pulled together in this splendid book all the raw material needed to spark a fresh discussion between the government and the media on how to function under our unique system of government in this ever-evolving information-rich environment.

  • Cyber Conflicts in International Relations: Framework and Case Studies
    Cyber Conflicts in International Relations: Framework and Case Studies Alexander Gamero-Garrido Engineering Systems Division Massachusetts Institute of Technology [email protected] | [email protected] Executive Summary Overview Although cyber conflict is no longer considered particularly unusual, significant uncertainties remain about the nature, scale, scope and other critical features of it. This study addresses a subset of these issues by developing an internally consistent framework and applying it to a series of 17 case studies. We present each case in terms of (a) its socio-political context, (b) technical features, (c) the outcome and inferences drawn in the sources examined. The profile of each case includes the actors, their actions, tools they used and power relationships, and the outcomes with inferences or observations. Our findings include: • Cyberspace has brought in a number of new players – activists, shady government contractors – to international conflict, and traditional actors (notably states) have increasingly recognized the importance of the domain. • The involvement of the private sector on cybersecurity (“cyber defense”) has been critical: 16 out of the 17 cases studied involved the private sector either in attack or defense. • All of the major international cyber conflicts presented here have been related to an ongoing conflict (“attack” or “war”) in the physical domain. • Rich industrialized countries with a highly developed ICT infrastructure are at a higher risk concerning cyber attacks. • Distributed Denial of Service (DDoS) is by far the most common type of cyber attack. • Air-gapped (not connected to the public Internet) networks have not been exempt from attacks. • A perpetrator does not need highly specialized technical knowledge to intrude computer networks.
