As the IoT continues to revolutionize industrial automation, the deployment of sensors has become widespread, offering real-time data collection and control. The Internet of Things permeates our daily lives, safeguarding privacy within security systems has become an urgent priority. Conventional security systems, frequently reliant on intrusive monitoring methods, raise user concerns about ethics and privacy. While connectivity offers many benefits, it also creates weaknesses that malicious actors can target. This study examines the various security challenges faced by IoT-enabled sensors in automation systems, including data privacy risks, unauthorized access, and potential system manipulation. The overview of Cyber Physical Production System (CPPS), elucidating their architecture, components. The various sources of attacks targeting automation systems, which play a critical role in modern industrial environments. This research contributes to advancing understanding of Cyber Physical Production System (CPPS) and cyber security in industrial automation, guiding future efforts to secure cyber-physical systems against evolving threats and measures.
