Perceived Threat Modeling for Cyber-Physical Systems

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Physical security is a critical component used to safeguard employees and prevent unauthorized access to critical infrastructures. This chapter presents the analysis of each of the three constructs, cognitive demographics, situational characteristics, and probability of intrusion, based on the perceived threat model. To fully understand the need for better physical security software systems, the chapter presents reviews the physical security and the associated software limitations. Information assurance (IA) is typically addressed from a logical security perspective due to the large volume of digitally stored information. A physical security system (PSS) is designed to employ a complementary combination of six components: intrusion detection and assessment, entry and search control, barriers, communications, testing and maintenance, and support systems, which are used to deter, detect, and delay an attack. The content analysis of the cognitive demographic construct demonstrated that subjects had different dispositions toward decision-making.
