Developed in 2018, PathTrace is a software package built with the intention of making path analysis simple and intuitive. PathTrace is a top-down pathway analysis software where a user is able to explore vulnerable pathways into a facility. The intention of utilizing a software tool like PathTrace is to characterize an existing physical protection system (PPS) and to upgrade the system to achieve a high level of response interruption, or probability of interruption (P_I) of the adversary. There are four steps for conducting path analysis using PathTrace. The first step is to identify an image to use to build the model and scale the model within PathTrace using a section of known distance (wall or fence perimeter, for example). The scaling process will produce a grid of cells through which the user is able to build a model. The second step is to fill out the grid of cells with four categories of materials: Barriers, Detection Areas, Jumps, and Targets. These materials apply associated delay and detection values to the cells in which they are applied. The third step is to represent the adversary and response forces. The adversaries are represented by their capabilities in interacting with the materials identified in step two, and the response is represented by how quickly they will be able to respond to an adversary attack. Finally, the user is able to take all of the information from the previous three steps and perform a Most Vulnerable Path (MVP) analysis. In this stage, the user is able to visualize vulnerable adversary pathways and reason about how to upgrade these pathways to provide a high level of P_I.

Scribe3D© is an application designed to allow users to develop risk threat scenarios on a 3D image of a facility/location of the users choosing. Once the facility/terrain is loaded, entities such as personnel, vehicles (ground and air), and structures/objects can be added. Then the user can make the entities move around the facility/terrain. Responder and Adversary forces can be outfitted with weapons and move from place to place on foot or in vehicles. In Scribe3D©, once the entities are identified, they can be moved to visualize realistic scenario situations by using a suite of tools to enhance decision making and scenario development. This manual can guide you through setting up and editing all aspects of Scribe3D© and guide you to the creation of a Scenario Exercise.
