Abstract: The traditional perimeter-based security model has become increasingly inadequate in addressing the dynamic and distributed nature of modern cloud computing environments. In response, the Zero Trust Security Architecture (ZTSA) has emerged as a paradigm shift in cybersecurity, promoting the principle of “never trust, always verify.” This paper surveys the foundational principles, components, and implementations of ZTSA within cloud ecosystems, examining how Zero Trust addresses challenges related to identity management, data security, network segmentation, and threat detection. The study explores key frameworks such as Google's BeyondCorp, the NIST Zero Trust Architecture model, and evaluates their integration with cloud service providers like AWS, Microsoft Azure, and Google Cloud. Furthermore, the survey assesses the current limitations, implementation barriers, and future directions for Zero Trust in hybrid and multi-cloud environments. This comprehensive analysis provides a valuable reference for cloud architects, IT security professionals, and researchers seeking to build resilient and adaptive security models in cloud-native infrastructures.
