Abstract

Zero Trust (ZT) is a security model that assumes no entity, whether inside or outside the network, is trusted by default. As organizations increasingly migrate their infrastructure to the cloud, traditional perimeter-based security models prove ineffective in protecting against advanced threats. This paper explores the implementation of Zero Trust in cloud environments and its impact on enhancing security in the modern era. By focusing on identity management, network segmentation, and continuous verification, the study highlights the key principles of Zero Trust and discusses its effectiveness in mitigating risks like data breaches and insider threats. The paper also examines best practices, challenges, and future trends in adopting Zero Trust within cloud ecosystems.
