Mapping Networks of Terrorist Cells

TLDR

Analyzing networks after an event is easy for prosecution, but mapping covert networks to prevent crime is much harder. The study investigates the challenge of mapping covert networks, focusing on the September 11, 2001 terrorist network. The authors analyze publicly available data to reconstruct the network surrounding the September 11, 2001 attacks. Using public data, they mapped part of the network centered on the 19 hijackers, providing partial insight into the organization but leaving gaps. The paper offers suggestions for future work and research.

Abstract

This paper looks at the difficulty in mapping covert networks. Analyzing networks after an event is fairly easy for prosecution purposes. Mapping covert networks to prevent criminal activity is much more difficult. We examine the network surrounding the tragic events of September 11th, 2001. Through public data we are able to map a portion of the network centered around the 19 dead hijackers. This map gives us some insight into the terrorist organization, yet it is incomplete. Suggestions for further work and research are offered.
