Cyber Physical Systems: Security Technologies, Application and Defense

New security threats have surfaced in response to the meteoric rise in the prevalence of Cyber-Physical Systems (CPS). The latest iteration of CPS has a wide range of flaws, dangers, attacks, and safeguards. However, there hasn't been any comprehensive research done on CPS security problems. In particular, it has been challenging to examine the issue using a single generalized model due to the variability of CPS elements and the diversity of CPS systems. In this study, we use a holistic security model to examine CPS safety. We examine the technologies at the perceptual, network, and application levels. Smart grids, transportation, healthcare, and residential applications, along with the most common problems and solutions. Since many studies did not focus on a particular use case, we categorize them into broad categories, such as ICSs, cloud servers, and embedded devices.
