Abstract
CPS is another fundamental infrastructure essential to today’s world these are systems where computational processes integrate with physically implemented control and action elements to implement intelligence and self-sufficiency. But complex threats in cyberspace can take advantage of this interrelation. In CPS setups, resource deficiency, interconnectivity, and complex topology expose multiple layers of vulnerability which traditional security solutions normally fail to address. Different levels of CPS, such as data gathering, data-transmitting, control level, and application level, can be enhanced for security by adopting the intelligent hierarchy presented in this study. In the attempt to minimize risk duration and redesign security, the model uses the concepts of adaptability and multiple layers of defence for detection, evaluation, and response to risks. Two examples of such threat detection methodologies include adaptive response and human learning-based anomaly detection approaches, which afford precise, quicker responses. The model offers high durability and enhanced availability under various CPS conditions because of flexibility and distribution. The structure’s performance is proven by testing and simulation of how it can prevent a range of cyber-attacks, reduce the reaction time, and allocate resources in the most effective way.
