The next‐generation future is dependent on the development and usage of technology by integrating computing, communicating, and control of models. CPS strongly focused to avoid challenges of medical care, shipping, and other areas. This chapter provides surveys of CPS research problems and tasks considered for development of CPS and privacy problems, threats, and clarifications for CPS. CPS increases various security challenges with present problems in markets. The main motivation is to identify the security threats related to CPS, challenges, attacks and problems facing, advantages, and drawbacks of the present security system, the main goal is to provide accurate security, reliable, efficient and safe surroundings.
