Mathematical Methods in Counterterrorism:
Tools and Techniques for a New Challenge
David L. Hicks, Nasrullah Memon, Jonathan D. Farley, and Torben Rosenørn
1 Introduction
Throughout the years mathematics has served as the most basic and fundamental
tool employed by scientists and researchers to study and describe a wide variety
of fields and phenomena. One of the most important practical application areas of
mathematics has been for national defense and security purposes. For example, dur-
ing the Second World War, the mathematical principles underlying game theory and
cryptography played a very important role in military planning. Since that time, it
has become clear that mathematics has an important role to play in securing victory
in any global conflict, including the struggle faced by national security and law en-
forcement officials in the fight against those engaged in terrorism and other illicit
activities.
Recent events of the past decade have produced an increased interest in and focus
upon the area of counterterrorism by a broad range of scholars, including mathe-
maticians. At the same time, government decision makers have often been skeptical
about mathematics and statistics, even while faced with the considerable challenges
of sifting through enormous amounts of data that might hold critically important
clues. Realizing that policy makers were not always receptive, the mathematical
