This session will discuss how to use Crime Prevention Through Environmental Design (CPTED) to protect critical infrastructure. CPTED is a holistic approach to design security into the built environment and make it more resilient and unattractive for incivilities, crime, violence, and terror. CPTED is based upon the concept that proper design and effective use of the built environment can lead to a reduction in both the incidence and fear of crime while improving the quality of life where we live, work, and play. CPTED strategies developed from this multi-disciplinary approach have been adopted by numerous professional organizations, and cities, internationally.
