Abstract
Smart manufacturing, driven by the Industrial Internet of Things (IIoT), is transforming real-time data sharing, predictive maintenance, and process automation. However, the increasing complexity and connectivity of IIoT environments present significant security and resilience challenges that threaten operational safety, data integrity, and business continuity. This paper presents a comprehensive review of secure and resilient architectures for IIoT in smart manufacturing, highlighting the interaction between enabling technologies (e.g., edge computing, AI/ML, blockchain) and emerging threats in the cyber-physical environment. We explore vulnerabilities and attack surfaces and examine resilience strategies such as redundancy, fault tolerance, and self-healing capabilities that ensure ongoing operations despite disruptions. Key standards and best practices, including ISA/IEC 62443 and NIST frameworks, are evaluated for their effectiveness and limitations. Emerging trends—such as AI-driven proactive security, cyber-physical systems convergence, and green security initiatives—are discussed alongside open challenges and trade-offs in IIoT environments. Our analysis underscores the need for holistic, adaptive, and industry-specific solutions to enable secure and resilient IIoT architectures that foster innovation, productivity, and safety in the era of digital and connected factories.
