Since the 9/11 terrorist attacks in the United States, serious concerns
were raised on domestic and international security issues. Consequently,
there has been considerable interest recently in technological
strategies and resources to counter acts of terrorism. In this context,
this book provides a state-of-the-art survey of the most recent advances
in the field of counterterrorism and open source intelligence,
demonstrating how various existing as well as novel tools and techniques
can be applied in combating covert terrorist networks. A particular
focus will be on future challenges of open source intelligence and
perspectives on how to effectively operate in order to prevent terrorist
activities.
