Advancements in Zero Trust Security Models for Next Generation Network Infrastructures

Abstract

Zero Trust Security (ZTS) has emerged as a critical approach to safeguarding digital assets against sophisticated threats in modern distributed networks. Unlike traditional perimeter-based models, ZTS assumes no implicit trust and continuously verifies every request. This paper explores the architecture, evolution, and real-world implementation of Zero Trust in next-generation infrastructures. It analyzes key technologies such as identity-based access, micro-segmentation, and continuous authentication. The study also compares deployment outcomes across cloud and hybrid environments, offering a roadmap for successful ZTS adoption.
