  • Abstract

    By Industry 4.0 has resulted in the prevalence of smart factories, in which there is a close relationship between computation, communication, and physical processes through cyber-physical systems (CPS). Even though productivity, flexibility, and efficiency are improved under this integration, new security challenges that have never been experienced previously and go beyond the traditional cybersecurity boundaries are created. Cyber-physical security (CPSec) is the provision of defensive of the cyber components, as well as physical processes against malicious attacks, failures, and system anomalies. The paper is a systematic and multifaceted review of the new trends in cyber-physical security of smart factories. It looks at the threat landscapes, attack vectors, architecture weaknesses, and intersection of the information technology (IT) and operational technology (OT) worlds. In addition, the article evaluates the innovative defense systems such as artificial intelligence-based intrusion detection systems, blockchain-based trust management systems, zero-trust-based architectures, and security validation using digital twins. An adaptable, resilient, and real-time threat response-focused layered security approach is suggested to smart manufacturing settings. Recent experimental data on the role of advanced CPSec strategies is presented based on the considerations of industrial case studies and simulations. Lastly, the paper identifies open research problems and future directions requirements in order to establish robust, scale up and smart cyber-physical security systems in next generation smart factories.
