Identity-Driven IoT Security in Telecom Ecosystems: Implications for Scalable and Trustworthy Digital Infrastructure
Abstract:
The rapid expansion of IoT ecosystems across modern telecommunications networks has significantly widened the cyber attack surface, exposing operators to escalating risks as millions of heterogeneous devices connect across diverse and often untrusted environments. Despite a more than 400% increase in connected devices over the past decade, core identity controls—including secure onboarding, credential governance, and lifecycle-based trust enforcement—have not scaled accordingly. This mismatch has resulted in persistent vulnerabilities such as device impersonation, unauthorized provisioning, static credential misuse, and long-lived identity decay. This article presents a cybersecurity-driven, Zero Trust identity architecture tailored for large-scale IoT environments. The framework integrates continuous identity verification, certificate-based authentication, distributed policy enforcement, and automated governance across edge, gateway, and MEC layers. By combining hardware-rooted identity, event-triggered validation, orchestrated credential rotation, predictive behavioral analytics, and automated containment, the architecture substantially reduces attack surfaces and operational burden. Evaluations show 30–60% reductions in unauthorized access attempts, misconfigurations, and SOC workload, enabling more efficient and effective threat response. Beyond technical improvements, identity-centric IoT security reinforces national resilience, enhances regulatory compliance, reduces fraud exposure, and supports sustainable scaling of critical telecom infrastructure. The findings demonstrate that identity is not an auxiliary control but the foundational cybersecurity mechanism required to secure the next generation of IoT-enabled digital infrastructure.
