The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars
engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their
use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy
has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J.
Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of
Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the
selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal
government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national
needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M.
Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of
eminent members of appropriate professions in the examination of policy matters pertaining to the health of the
public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional
charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care,
research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad
community of science and technology with the Academy’s purposes of furthering knowledge and advising the
federal government. Functioning in accordance with general policies determined by the Academy, the Council has
become the principal operating agency of both the National Academy of Sciences and the National Academy of
Engineering in providing services to the government, the public, and the scientific and engineering communities.
The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and
Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Proceedings of a Workshop on Deterring CyberAttacks: Informing Strategies and Developing Options for U.S. Policy
Preface
In a world of increasing dependence on information technology, the prevention of cyberattacks on
a nation’s important computer and communications systems and networks is a problem that looms
large. Given the demonstrated limitations of passive cybersecurity defense measures (that is, measures
taken unilaterally by an organization to increase the resistance of an information technology system or
network to attack), it is natural to consider the possibility that deterrence might play a useful role in
preventing cyberattacks against the United States and its vital interests.
At the request of the Office of the Director of National Intelligence, the National Research Council
(NRC) undertook a project entitled “Deterring Cyberattacks: Informing Strategies and Developing
Options for U.S. Policy.” The two-phase project aimed to foster a broad, multidisciplinary examination
of strategies for deterring cyberattacks on the United States and of the possible utility of these strategies
for the U.S. government (see Box P.1 for the statement of task).
In the first phase, the Committee on Deterring Cyberattacks: Informing Strategies and Developing
Options for U.S. policy produced a letter report, released in March 2010 and reprinted in Appendix A
of this volume, that provided basic information needed to understand the nature of the problem and to
articulate important questions that can drive research regarding ways of more effectively preventing,
discouraging, and inhibiting hostile activity against important U.S. information systems and networks.
The second phase of this project entailed selecting appropriate experts to write papers on questions
raised in the letter report. A number of experts, identified by the committee, were commissioned to
write these papers under contract with the National Academy of Sciences. Commissioned papers were
discussed at a public workshop held June 10-11, 2010, in Washington, D.C., and authors revised their
papers after the workshop.
In addition to commissioning papers, the NRC sponsored a prize competition for papers that
addressed one or more of the questions raised in the letter report. Two of these papers were singled out
for recognition as noted on p. xii in the Contents and have been included in Group 7 of this volume.
Although the authors were selected and the papers reviewed and discussed by the committee, the
individually authored papers do not reflect consensus views of the committee. Under NRC guidelines
for conducting workshops, workshop activities do not seek consensus, and proceedings (such as the
present volume) cannot be said to represent an NRC view on the subject at hand. Furthermore, indi-
vidual members of the committee may agree or disagree with the findings, conclusions, or analysis of

Statement of Task
An ad hoc committee will oversee a two-phase activity to foster a broad, multidisciplinary exami-
nation of deterrence strategies and their possible utility to the U.S. government in its policies toward
preventing cyberattacks. In the first phase, the committee will prepare a letter report identifying the key
issues and questions that merit examination. In the second phase, the committee will engage experts to
prepare papers that address key issues and questions, including those posed in the letter report. The
papers will be compiled in a National Research Council publication and/or published by appropriate
journals. This phase will include a committee meeting and a public workshop to discuss draft papers,
with authors finalizing the papers following the workshop.
any given paper in this volume, and the reader should view these papers as offering points of departure
that can stimulate further work on the topics discussed.
The papers presented in this volume are published essentially as received from the authors, with
some proofreading corrections made as limited time allowed.
The meeting agenda and biosketches of the speakers are provided in Appendixes B and C, respec-
tively. Appendix D provides biosketches of the committee and staff.
