The document discusses risks and vulnerabilities in cyber-physical systems (CPS), especially those used in defense applications. It notes that CPS integrate computation and physical processes to monitor and control systems. In the defense sector, CPS and embedded systems are critical to network-centric warfare approaches. However, these systems are vulnerable to hardware Trojans, which are malicious modifications made during integrated circuit manufacturing that can undermine trust in affected systems. Specifically, hardware Trojans could mislead information sharing between nodes in a network-centric system, degrading situational awareness and decision making with potentially severe consequences for military missions. The document calls for preventive methods at the design, fabrication, and post-fabrication stages to help address these risks
