COMPREHENSIVE SECURITY APPROACH: A proper security assessment does not focus solely on crime. Threats posed by natural disasters such as floods, earthquakes, hurricanes and tornados should also be taken into account, as should the threat of martial law or government-imposed curfews that could leave residents isolated and, perhaps, without essential supplies and services. In such environments, a good security plan will provide for self-sufficiency in case of disruptions to infrastructure and transportation. It will also include an evacuation procedure.
