Morral, Andrew R: Understanding the Role of Deterrence in Counterterrorism Security

Deterrence--a central feature of counterterrorism security systems and a major factor in the cost-effectiveness of many security programs--is not well understood or measured. This paper offers a framework for understanding how security systems may deter or displace attacks and how to measure the relative deterrent value of alternative systems. This framework may aid in attempts to achieve increased security benefits with limited resources.
