🤖 AI Summary
This study addresses the fragmented understanding and critical research gaps at the intersection of IoT security and Zero Trust principles, where academic and industrial perspectives remain largely disconnected. Employing a multivocal literature review (MLR) methodology, the work synthesizes 68 academic and 36 industrial sources through qualitative content analysis and a cross-domain comparative framework, systematically evaluating them against NIST’s Zero Trust standards. The analysis reveals that while academic research primarily focuses on redesigning IoT architectures to align with Zero Trust tenets, industry efforts concentrate on integrating Zero Trust into existing infrastructures—approaches that are complementary yet divergent in emphasis. The study identifies three key research gaps: sociotechnical comprehension, cost-benefit assessment, and interdisciplinary collaboration, offering a structured roadmap to foster synergistic innovation across academia and industry.
📝 Abstract
The convergence of Internet of Things (IoT) security and Zero Trust (ZT) principles is a trending topic, demanding a comprehensive, multi-perspective analysis. We present the first multivocal literature review (MLR) on this topic, combining 68 academic and 36 industrial studies. This comprehensive review identifies two complementary yet divergent perspectives: academia focuses on IoT compliance with ZT principles through IoT modifications, while industry prioritizes practical integration within existing ZT frameworks guided by NIST standards. The analysis reveals critical research gaps in socio-technical understanding, cost-benefit evaluation, and interdisciplinary collaboration, highlighting these as key directions for future research.
