The Threat Differentiation Model illustrates how to break down and isolate all the elements and sub-elements of a mishap, disruption, or crime, the confluence of which causes any of them. It takes an opportunity for a hazard and an object of mishap to meet at an opportune time and place for a mishap to occur. The hazard or threat is constituted by three sub-elements namely a person or a phenomenon, their capacity or potential, and their motive, intent, or tendency. The object of mishap is composed of the asset or value that induces the motive, the target’s susceptibility, and vulnerability. The opportunity is composed of the time, place, and prevailing conditions. Removing any of the sub-elements will eliminate the element. Without one of its elements, a mishap or crime cannot occur. The Model is a practical, all-around, and

a handy tool that can be used to design a security measure to prevent the occurrence of a specific mishap. It can also be used to determine how and why a mishap occurred for a successful investigation. It can be applied by a single person for him/herself or for larger entities. It can also reduce the cost of security. The Threat Differentiation Model is covered in the book, ”The Art and Science of Security©2012.
