Physical security is a vital part of any organization’s operations. In spite of advancements in new technologies for personnel access control and security development life cycles, the need exists for a pre-design schematic specification that bridges the gap between “natural communication” (e.g., English) and semiformal computing-based diagramming descriptions (e.g., UML). Such a specification can play an important role in facilitating understanding among all stakeholders and as a first step to implementation and development of programming-based diagrams. Most of the reported research in the area of physical security has been driven by practical objectives; the value of these studies is limited because of their static representations based on static conceptions of space. This paper proposes to develop a security system based on the notion of security as a machine. The machine is an abstract apparatus with synchronic order of five states (stages): creation, release, transfer, receipt, and process. The resultant model views a security environment in terms of flows of things and uses this flow to establish a system-based representation. The paper introduces a sample of such a map for two cases: (i) an airport luggage handling process that involves a possibly compromised human-based portion, and (ii) an insider threat scenario in which the attacker is one of the personnel allowed to physically access the premises. The resultant depiction seems suitable for security operations, training, and planning.
