Physical security controls aim to reduce risk through their ability to systematically deter, or detect, delay and respond against deviant acts within a risk context. Holistically the aim is to increase the difficulty and risks while reducing the rewards associated with an act of deviance as captured in Clarke’s Situational Crime Prevention (SCP) framework. The efficacious implementation of such controls commensurate with the risk context requires a considered undertaking referred as informed decision‐making. Informed decision‐making is effective when a suitable choice is made accordant with base rate data that achieves its defined objectives within costs versus benefits framework. The study examined the feasibility of developing a decision support tool to enhance the selection of a suitable barrier fence system, in‐line with defence in depth to increase the efforts and risks, and reduce the rewards associated with unlawful access. The study found that a decision support tool can be developed comprising of the various contextual inputs and their relationships in achieving a contextually suitable barrier fence system, as a result enhancing the selection of situational crime prevention elements.
