Cyber-Physical Systems Security: Challenges and Solutions in IoT Devices

Abstract

The integration of Cyber-Physical Systems (CPS) with Internet of Things (IoT) devices has revolutionized many sectors, including healthcare, manufacturing, transportation, and smart cities. However, the rapid proliferation of IoT devices in CPS environments has introduced significant security challenges. These systems, which bridge the gap between computational processes and the physical world, are vulnerable to various attacks that can compromise both their integrity and the safety of their users. This paper explores the key security challenges in CPS when applied to IoT devices, including issues related to data privacy, unauthorized access, and the vulnerabilities arising from resource-constrained devices. Additionally, we examine the unique characteristics of CPS that make traditional security measures inadequate, such as real-time constraints and the need for high reliability. The paper reviews a range of solutions to enhance CPS security, including encryption techniques, anomaly detection systems, and the role of machine learning and artificial intelligence in proactive threat identification. We also discuss the importance of adopting a layered security architecture and establishing industry-specific standards and regulations to mitigate risks. This paper provides a comprehensive overview of the current state of CPS security in IoT environments and highlights the importance of continued research and development to address emerging security threats in this rapidly evolving field.
